The Man Himself, taking notes on what look like Giraffatitan caudals.

Here’s how I got my start in research. Through a mentorship program, I started volunteering at the Oklahoma Museum of Natural History in the spring of 1992, when I was a junior in high school. I’d been dinosaur-obsessed from the age of three, but I’d never had an anatomy course and didn’t really know what I was doing. Which is natural! I had no way of knowing what I was doing because I lacked training. Fortunately for me, Rich Cifelli took me under his wing and showed me the ropes. I started going out on digs, learned the basics of curatorial work, how to mold and cast fossils, how to screenwash matrix and then pick microfossils out of the concentrate under a dissecting microscope, and—perhaps most importantly—how to make a rough ID of an unidentified bone by going through the comparative element collection until I found the closest match.

All set, right? Ignition, liftoff, straight path from there to here, my destiny unrolling before me like a red carpet.

No.

It could have gone that way, but it didn’t. I had no discipline. I was a high-achieving high school student, but it was all to satisfy my parents. When I got to college, I didn’t have them around to push me anymore, and I’d never learned to push myself. I went off the rails pretty quickly. Never quite managed to lose my scholarships, without which I could not have afforded to be in college, period, but I skimmed just above the threshold of disaster and racked up a slate of mediocre grades in courses from calculus to chemistry. I even managed to earn a C in comparative anatomy, a fact which I am now so good at blocking out that I can go years at a time without consciously recalling it.

After three years of this, I had the most important conversation of my life. Because I was a zoology major I’d been assigned a random Zoology Dept. faculty member as an undergrad advisor. I was given to Trish Schwagmeyer, not because we got on well (we did, but that was beside the point) or had similar scientific interests, just luck of the draw. And it was lucky for me, because in the spring of 1996 Trish looked at my grades from the previous semester, looked me in the eye, and said, “You’re blowing it.” She then spent the next five minutes explaining in honest and excruciating detail just how badly I was wrecking my future prospects. I’ve told this story before, in this post, but it bears repeating, because that short, direct, brutal-but-effective intervention became the fulcrum for my entire intellectual life and future career.

The holotype specimen of Sauroposeidon coming out of the ground in 1994.

Roughly an hour later I had the second most important conversation of my life, with Rich Cifelli. While I’d been lost in the wilderness my museum volunteering had petered out to zero, and Rich would have been completely justified in telling me to get lost. Not only did he not do that, he welcomed me back into the fold, in a terrifyingly precise recapitulation of the Biblical parable of the prodigal son. When I asked Rich if I could do an independent study with him in the next semester, he thought for a minute and said, “Well, we have these big dinosaur vertebrae from the Antlers Formation that need to be identified.” Which is how, at the age of 21, with a rubble pile of an academic transcript and no real accomplishments to stand on, I got assigned to work on OMNH 53062, the future holotype of Sauroposeidon proteles.

I was fortunate in four important ways beyond the forgiveness, patience, and generosity of Richard Lawrence Cifelli:

  • OMNH 53062 was woefully incomplete, just three and a half middle cervical vertebrae, which meant that the project was small enough in concept to be tractable as an independent study for an undergrad. Rich and I both figured that I’d work on the vertebrae for one semester, come up with a family-level identification, and maybe we’d write a two-pager for Oklahoma Geology Notes documenting the first occurrence of Brachiosauridae (or whatever it might turn out to be) in the vertebrate fauna of the Antlers Formation.
  • Because the specimen was so incomplete, no-one suspected that it might be a new taxon, otherwise there’s no way such an important project would have been assigned to an undergrad with a spotty-to-nonexistent track record.
  • Despite the incompleteness, because the specimen consisted of sauropod vertebrae, it held enough characters to be identifiable–and eventually, diagnosable. Neither of those facts were known to me at the time.
  • All of Rich’s graduate students were already busy with their own projects, and nobody else was about to blow months of time and effort on what looked like an unpromising specimen.

NB: this guy is not a prodigy.

There is a risk here, in that I come off looking like some kind of kid genius for grasping the importance of OMNH 53062, and Rich’s other students look like fools for not seeing it themselves. It ain’t like that. The whole point is that nobody grasped the importance of the specimen back then. It would take Rich and me a whole semester of concentrated study just to come to the realization that OMNH 53062 might be distinct enough to be diagnosable as a new taxon, and a further three years of descriptive and comparative work to turn that ‘maybe’ into a paper. People with established research programs can’t afford to shut down everything else and invest six months of study into every incomplete, garbage-looking specimen that comes down the pike, on the off chance that it might be something new. Having the good judgment to not pour your time down a rat-hole is a prerequisite for being a productive researcher. But coming up with a tentative ID of an incomplete, garbage-looking specimen is a pretty good goal for a student project: the student learns some basic comparative anatomy and research skills, the specimen gets identified, no existing projects get derailed, and no-one established wastes their time on what is most likely nothing special. If the specimen does turn out to be important, that’s gravy.

So there’s me at the start of the fall of 1996: with a specimen to identify and juuuust enough museum experience, from my high school mentorship, to not be completely useless. I knew that one identified a fossil by comparing it to known things and looking for characters in common, but I didn’t know anything about sauropods or their vertebrae. Rich got me started with a few things from his academic library, I found a lot more in OU’s geology library, and what I couldn’t find on campus I could usually get through interlibrary loan. I spent a lot of time that fall standing at a photocopier, making copies of the classic sauropod monographs by Osborn, Hatcher, Gilmore, Janensch, and others, assembling the raw material to teach myself sauropod anatomy.

The sauropod monographs live within arm’s reach of my office chair to this day.

In addition to studying sauropods, I also started going to class, religiously, and my grades rose accordingly. At first I was only keeping up with my courses so that I would be allowed to continue doing research; research was the carrot that compelled me to become a better student. There was nothing immediate or miraculous about my recovery, and Rich would have to give me a few well-deserved figurative ass-kickings over the next few years when I’d occasionally wander off course again. But the point was that I had a course. After a few months I learned—or remembered—to take pride in my coursework. I realized that I had never stopped defining myself in part by my performance, and that when I’d been adrift academically I’d also been depressed. It felt like crawling out of a hole.

(Aside: I realize that for many people, depression is the cause of academic difficulty, not the reverse, and that no amount of “just working harder” can offset the genuine biochemical imbalances that underlie clinical depression. I sympathize, and I wish we lived in a world where everyone could get the evaluation and care that they need without fear, stigma, crushing financial penalties, or all of the above. I’m also not describing any case here other than my own.)

What fresh hell is this? (Apatosaur dorsal from Gilmore 1936)

Out of one hole, into another. The biggest problem I faced back then is that if you are unfamiliar with sauropod vertebrae they can be forbiddingly complex. The papers I was struggling through referred to a pandemonium of laminae, an ascending catalog of horrors that ran from horizontal laminae and prespinal laminae through infraprezygapophyseal laminae and spinopostzygapophyseal laminae. Often these features were not labeled in the plates and figures, the authors had just assumed that any idiot would know what a postcentrodiapophyseal lamina was because, duh, it’s right there in the name. But that was the whole problem: I didn’t know how to decode the names. I had no map. SV-POW! tutorials didn’t exist. Jeff Wilson’s excellent and still-eminently-useful 1999 paper codifying the terminology for sauropod vertebral laminae was still years in the future.

Then I found this, on page 35 of Werner Janensch’s 1950 monograph on the vertebrae of what was then called Brachiosaurus brancai (now Giraffatitan):

It was in German, but it was a map! I redrew it by hand in my very first research notebook, and as I was copying down the names of the features the lightbulb switched on over my head. “Diapophyse” meant “diapophysis”, and it was the more dorsal of the two rib attachments. “Präzygapophyse” was “prezygapophysis”, and it was one of the paired articular bits sticking out the front of the neural arch. And, crucially, “Präzygodiapophysealleiste” had to be the prezygodiapophyseal lamina, which connected the two. And so on, for all of the weird bits that make up a sauropod vertebra.

It’s been 22 years and I still remember that moment of discovery, my pencil flying across the page as I made my own English translations of the German anatomical terms, my mind buzzing with the realization that I was now on the other side. Initiated. Empowered. I felt like I had pulled the sword from the stone, found Archimedes’ lever that could move the world. In the following weeks I’d go back through all of my photocopied sauropod monographs with my notebook open to the side, reading the descriptions of the vertebrae for the second or third times but understanding them for the first time, drawing the vertebrae over and over again until I could call up their basic outlines from memory. This process spilled over from the fall of 1996 into the spring of 1997, as Rich and I realized that OMNH 53062 would require more than one semester of investigation.

My memories of those early days of my sauropod research are strongly shaped by the places and circumstances in which I was doing the work. Vicki and I had gotten married in the summer of 1996 and moved into a two-bedroom duplex apartment on the north side of Norman. The upstairs had a long, narrow bathroom with two sinks which opened at either end onto the two upstairs bedrooms, the one in which we slept and the one we used as a home office. In the mornings I could get showered and dressed in no time, and while Vicki was getting ready for work or school I’d go into the office to read sauropod papers and take notes. Vicki has always preferred to have music on while she completes her morning rituals, so I listened to a lot of Top 40 hits floating in from the other upstairs rooms while I puzzled out the fine details of sauropod vertebral anatomy.

Two songs in particular could always be counted on to play in any given hour of pop radio in the early spring of 1997: Wannabe by the Spice Girls, and Lovefool by the Cardigans. I am surely the only human in history to have this particular Pavlovian reaction, but to this day when I hear either song I am transported back to that little bedroom office where I spent many a morning poring over sauropod monographs, with my working space illuminated by the light of the morning sun pouring through the window, and my mind illuminated by Werner Janensch, who had the foresight and good grace to give his readers a map.

Figure 5 from my undergraduate thesis: OMNH 53062 in right lateral view.

If you want to know what I thought about OMNH 53062 back in 1997, you can read my undergraduate thesis—it’s a free download here. Looking back now, the most surprising thing to me about that thesis is how few mentions there are of pneumaticity. I met Brooks Britt in the summer of 1997 and had another epochal conversation, in which he suggested that I CT scan OMNH 53062 to look at the air spaces inside the vertebrae. I filed my undergrad thesis in December of 1997, and the first session CT scanning OMNH 53062 took place in January, 1998. So in late 1997 I was still a pneumaticity n00b, with no idea of the voyage I was about to embark upon.

In 2010, after I was settled in as an anatomist at Western University of Health Sciences, I wrote a long thank-you to Trish Schwagmeyer. It had been 14 years since that pivotal conversation, but when she wrote back to wish me well, she still remembered that I’d gotten a C in comparative anatomy. I’d have a chance to make amends for that glaringly anomalous grade later the same year. At ICVM in Punta del Este, Uruguay, I caught up with Edie Marsh-Matthews, who had taught my comparative anatomy course back when. I apologized for having squandered the opportunity to learn from her, and she graciously (and to my relief) shifted the conversation to actual comparative anatomy, the common thread that connected us in the past and the present.

If the story has a moral, it’s that I owe my career in large part to people who went out of their way to help me when I was floundering. And, perhaps, that the gentle approach is not always the best one. I needed to have my head thumped a few times, verbally, to get my ass in gear, when less confrontational tactics had failed. I slid easily through the classrooms of dozens of professors who watched me get subpar grades and didn’t try to stop me (counterpoint: professors are too overworked to invest in every academic disaster that comes through the door, just like paleontologists can’t study every garbage specimen). If Trish Schwagmeyer and Rich Cifelli had not decided that I was worth salvaging, and if they not had the grit to call me out on my BS, I wouldn’t be here. As an educator myself now, that thought haunts me. I hope that I will be perceptive enough to know when a student is struggling not because of a lack of ability but through a lack of application, wise enough to know when to deploy the “you’re blowing it” speech, and strong enough to follow through.

Final bonus image so when I post this to Facebook, it won’t grab the next image in line and crop it horribly to make a preview. This is me with OMNH 1670, in 2003 or 2004, photo by Andrew Lee.

Nothing too serious here, just a fun shot I got while in the collections at BYU this past week. The Brachiosaurus element is metacarpal 1 (thumb column) from BYU 4744, the Potter Creek material. I highlighted my own metacarpal 3. There is a metacarpal 3 from this specimen, but I didn’t see it on the shelf. According to D’Emic and Carrano (2019), the MC3 is 60cm long, vs 57cm for this MC1. So this photo could have been 3cm more impressive!

Oh, ignore the tag on the left that says “radius”. You could be forgiven for thinking that the bone I have my hand on is a radius, but the radius from this individual is 1.34 meters long, or about two-and-a-third times the length of this metacarpal.

Two professionals, hard at work.

After this year’s SVPCA, Vicki and London and I spent a few days with the Taylor family in the lovely village of Ruardean. It wasn’t all faffing about with the Iguanodon pelvis, the above photo notwithstanding. Mike and I had much to discuss after the conference, in particular what the next steps might be for the Supersaurus project. Mike has been tracking down early mentions of Supersaurus, and in particular trying to determine the point at which Jensen decided that it might be a diplodocid rather than a brachiosaurid. I recalled that Gerald Wood discussed Supersaurus in his wonderful 1982 book, The Guinness Book of Animal Facts and Feats. While on the track of Supersaurus, I stumbled across this amazing claim in the section on Diplodocus (Wood 1982: p. 209):

According to De Camp and De Camp (1968) these giant sauropods may have been able to regenerate lost parts, and they mention another skeleton collected in Wyoming which appeared to have lost about 25 per cent of its tail to a carnosaur and then regrown it — along with 21 new vertebrae!

De Camp and De Camp (1968) is a popular or non-technical book, The Day of the Dinosaur. Used copies can be had for a song, so I ordered one online and it was waiting for me when I got back to California.

The Day of the Dinosaur is an interesting book. L. Sprague De Camp and Catherine Crook De Camp embodied the concept of the “life-long learner” before there was a buzzword to go with it. He had been an aerospace engineer in World War II, and she had been an honors graduate and teacher, before they turned to writing full time. Individually and together, they produced a wide range of science fiction, fantasy, and nonfiction books over careers that spanned almost six decades. The De Camps’ writing in The Day of the Dinosaur is erudite in range but conversational in style, and they clearly kept up with current discoveries. They also recognized that science is a human enterprise and that, like any exploratory process, it is marked by wildly successful leaps, frustrating wheel-spinning, and complete dead ends. I was pleasantly surprised to find that the authors were completely up to speed on plate tectonics, an essentially brand-new science in 1968, and they explain it as an alternative to older theories about immensely long land bridges or sunken continents.

At the same time, the book arrived just before the end-of-the-1960s publications of John Ostrom and Bob Bakker that kicked off the Dinosaur Renaissance, so there’s no mention of warm-blooded dinosaurs. The De Camps’ sauropods and duckbills are still swamp-bound morons, “endlessly dredging up mouthfuls of soft plant food and living out their long, slow, placid, brainless lives” (p. 142), stalked by ‘carnosaurs’ that were nothing more than collections of teeth relentlessly driven by blind instinct and hunger. The book is therefore an artifact of a precise time; there was perhaps a year at most in the late 1960s when authors as technically savvy as the De Camps would have felt obliged to explain plate tectonics and its nearly-complete takeover of structural geology (which had just happened), but not to comment on the new and outrageous hypothesis of warm-blooded, active, terrestrial dinosaurs (which hadn’t happened yet).

The book may also appeal to folks with an interest in mid-century paleo-art, as the illustrations are a glorious hodge-podge of Charles R. Knight, Neave Parker, photos of models and mounted skeletons from museums, life restorations reproduced from the technical literature, and original art produced for the book, including quite a few line drawings by one L. Sprague De Camp. Roy Krenkel even contributed an original piece, shown above (if you don’t know Krenkel, he was a contemporary and sometime collaborator of Al Williamson and Frank Frazetta, and his art collection Swordsmen and Saurians is stunning and still gettable at not-completely-ruinous prices; I’ve had mine since about 1997).

ANYWAY, as entertaining as The Day of the Dinosaur is, it doesn’t do much to help us regenerate the tale of the regenerated tail. Here’s the entire story, from page 114:

Sauropods, some students think, had great powers of regenerating lost parts. One specimen from Wyoming is thought to have lost the last quarter of its tail and regrown it, along with twenty-one new tail vertebrae. That is better than a modern lizard can do; for the lizard, in regenerating its tail, grows only a stumpy approximation of the original, without new vertebrae.

That’s it. No sources mentioned or cited, so no advance over Wood in terms of tracking down the origin of the story.

Massospondylus tail with traumatic amputation at caudal 25 (Butler et al. 2013: fig. 1A).

To be clear, I don’t really think there is a sauropod that regrew its tail, especially since we have evidence for traumatic tail amputation without regeneration in the basal sauropodomorph Massospondylus (Butler et al. 2013), in the theropod Majungasaurus (Farke and O’Connor 2007), and in a hadrosaur (Tanke and Rothschild 2002). But I would love to learn how such a story got started, what the evidence was, how it was communicated, and most importantly, how it took on a life of its own.

If anyone knows any more about this, I’d be very grateful for any pointers. The comment thread is open.

As usual I came back from SVPCA to a mountain of un-dealt-with day-job work, which is why it’s taken me so long to get this post done and up. I wanted to get it posted as quickly as I could decently arrange, because I had a fantastic time at this year’s meeting and I wanted to document a few reasons why, both to thank this year’s hosts and to perhaps inspire the organizers of future meetings.

A shot from the back of the banquet-hall-turned-lecture-theater during Mike’s talk.

1. Space

This year’s presentation space was unlike any I can remember from previous SVPCAs. Instead of being in a lecture hall, talks were held in a big ballroom, and attendees sat in chairs at big circular banquet tables. This had a LOT of positive effects: no edging along long rows of seats to get in or out between talks, easy discussion around and between the tables at the breaks, the opportunity for a group of people to sit together as a group (vs a line or same-facing block), plenty of space to set notebooks, laptops, papers, pens, drinks, etc. I realize that meeting space is probably one of the things that conference organizers have the least control over, but at least from what I saw this year I’d say the ballroom model works even better than the lecture hall model, so that’s a possible consideration for the future.

2. Time

Owing to the smaller-than-normal number of abstract submissions — possibly a function of the meeting being on an island rather than the, uh, somewhat larger island of Great Britain — everyone who asked for a talk got one, and the talk slots were long enough for full 15-minute talks and 5 minutes for questions. So the meeting seemed decompressed. No-one really rushed through their talks (although Mike did speak very quickly), and there was usually plenty of time for questions, and the all-important coffee top-up or between-breaks bio-refresh. I know that a fuller conference is in some ways a healthier conference, and I still maintain that if talks have to be trimmed at future meetings, established players like myself should take the hit so students and early-career-researchers can have some runway, but I still appreciated the more relaxed pace of this meeting.

3. Food and drink

Food and drink service was probably the best that I have experienced at a paleo conference, full stop. I wish I had taken a photo of the ranked rows of coffee cups on saucers, because they never ran out. I don’t think we ever ran out of coffee, either. A lunch of sandwiches, crisps, veggies, and hummus (edit: and cheese, lots of beautiful cheese!) was provided on Thursday and Friday all three days of the conference, and from what I saw, the lunches ran down to a bare handful of sandwiches at the very end but didn’t quite run out — and this was after everyone had ample opportunity to go back for more. Simply an outstanding job.

If I had one quibble, it was that the bar at Cowes Yacht Haven opened about five minutes before the start of Don Henderson’s Fox Lecture on Wednesday evening, without warning and after a lot of people (Mike and me included) had brought in drinks from outside, which we were then told we couldn’t drink on the premises. I realize that the opening and closing of the yacht club bar was probably outside the control of the organizers, but it was an annoyance for those of us who wanted to have a drink with the evening lecture.

4. Exhibitors

I admit to being disappointed when I realized that the meeting would be at Cowes rather than near the Dinosaur Isle museum in Sandown. We did get to visit the museum for the Tuesday evening icebreaker, but other than that we were in a different town entirely. The organizers’ clever solution was to bring the fossils to the paleontologists: several local collectors brought fossils for us to pore over on breaks and during poster time. This was particularly great for Mike, Jessie, and me, since so many of the fossils on display were from sauropods. Jessie and I were able to recognize neural canal ridges in the vertebrae of a rebbachisaurid for the first time, and we were able to use a brachiosaur caudal to demonstrate the ridges to Femke Holwerda, who then told us she’d seen them in a cetiosaur caudal. So our research made meaningful advancements because of the specimens on display, and we made useful contacts.

Speaking of Femke, her big Patagosaurus redescription has been accepted for publication at an OA outlet, so look for that most-welcome work in the not-too-distant future.

There were also paleoartists among the exhibitors, including John Sibbick, Mark Witton, and Luis Rey, among others, including some local artists. I picked up a nice print of a hand-drawn sauropod caudal by Trudie Wilson (this Trudie Wilson, not that Trudie Wilson, although I’m sure she’s a wonderful person too), which I need to do a whole post about, and will soon. I can’t remember now who proposed it, but someone remarked in one of the open sessions about how nice it was to have so much paleoart on display, and that maybe that was something that future meetings could lean into, including having paleoartists give talks about their art. That’s not unprecedented — John Conway and Bob Nicholls have both given presentations on paleoart at previous meetings, either in regular sessions or at evening social functions — but it is a great idea, and one I heartily endorse.

5. Proximity to everything else

Mike did sterling work finding an AirBnB house for a bunch of us (Mike, Darren, Mark Evans, Femke Holwerda, Jeff Liston, Mark Witton, Georgia Witton-Maclean, and Vicki and London and me) that was 300 feet from the entrance to Cowes Yacht Haven and about 700 feet from the banquet hall where the talks were held. I don’t think I’ve ever had such a short walk between my lodgings and the talk venue, even when I’ve stayed in the hotel where the conference was being held. There was also a Sainsbury’s grocery store, a bank of ATMs, and a bunch of restaurants within, seriously, a two-minute walk of the venue. I realize that this was also a lucky circumstance, not readily repeatable for other meetings that take place in museums or university lecture halls at some remove from commercial districts, but it sure was nice. If you had ten minutes, you could legit pop out to Sainsbury’s for some crisps or a beer, and be back at your seat with time to spare.

6. Loot

This one is purely personal, and mostly outside the organizers’ control. (Although they did carelessly put those exhibitors right in the path of my wallet, which fortunately was only running at about Category 3 this trip.) I’m only listing it here to guilt me into finishing the post (or posts) about the items I acquired on the trip, but folks, I did all right. More on that later.

So, a huge thank-you to the organizers of this year’s SVPCA for pulling off such a comfortable and enjoyable meeting. It was a gem. For more on what it was like, please see this post by Emma Nicholls, Deputy Keeper of Natural History at London’s Horniman Museum. If you know of other post-SVPCA conference reviews or retrospectives, please post them in the comments.

My talk (Taylor and Wedel 2019) from this year’s SVPCA is up!

The talks were not recorded live (at least, if they were, it’s a closely guarded secret). But while it was fresh in my mind, I did a screencast of my own, and posted it on YouTube (CC By). I had to learn how to do this for my 1PVC presentation on vertebral orientation, and it’s surprisingly straightforward on a Mac, so I’ve struck while the iron is hot.

For the conference, I spoke very quickly and omitted some details to squeeze the talk into a 20-minute slot. In this version, I go a bit slower and make some effort to ensure it’s intelligible to an intelligent layman. That’s why it runs closer to half an hour. I hope you’ll find it worth your time.

We’re just back from an excellent SVPCA on the Isle of Wight. We’ll write more about it, but this time I just want to draw attention to a neat find. During a bit of down time, Matt and Vicki were wandering around West Cowes (the town where the scientific sessions were held), when they stumbled across a place called That Shop. Intrigued by all the Lego figures in the window, they went in, and Matt found a small section of fossils. Including … an Iguanodon pelvis, supposedly certified as such by the Dinosaur Isle museum.

21A47352-31E1-43EE-B1E0-6432C6D7D366

Here it is: I imagine that whoever classified it read this elongate concave surface as part of the acetabulum. Matt’s hypothesis is that they mistook it for a sacral vertebra and that became “pelvis” via over-simplification.

It’s about 18 cm in a straight line across the widest part, or 20 cm around the curve.

Here is an actual documentary record of Matt’s moment of discovery:

Yep, you got it! It’s a sauropod vertebra! (Matt would never have spent good money on a stinkin’ appendicular element of a stinkin’ ornithopod.)

Specifically, it’s the bottom half of the front part of the centrum of a dorsal vertebra:

Eucamerotus” dorsal vertebra NHMUK PV R88 in right lateral and anterior views. Non-faded portions show the location of the Wedel Specimen. Modified from Hulke (1880: plate IV).

In these photos, we’re looking down into it more or less directly dorsal view, with anterior to the left. Click through the photos, and — once you know what you’re looking at — you can clearly see the pneumatic spaces: nice patches of finished bone lining the camellae, with trabecular bone in between.

Clearly there’s nowhere near enough of this to say what it is with any certainty. But our best guess is that it seems compatible with a titanosauriform identity, quite possibly in same space as the various Wealden sauropod dorsals that have been assigned to Ornithopsis or Eucamerotus.

Sorry to you all for the recent radio-silence here on SV-POW!. Matt and I are hard at work preparing our presentations for SVPCA 2019, which will take place on the Isle of Wight next week. Delightfully, not only will Matt be joining us this year, but so will his wife, forensic anthropologist celebre Vicki; and their son London.

Exterior of the Dinosaur Isle museum, Sandown, Isle of Wight, last known resting place of the vertebra known as “Angloposeidon” and the venue for the SVPCA 2019 drinks reception.

Anyway, since we have effectively prorogued SV-POW! until after the conference, I’d like to leave you with the delightful fact that the whole of last year’s conference is freely available to watch on YouTube.

We’ll hope to see some of you next week on the Isle of Wight — do come up and say hi, we always like to meet our readers. I hope that this year’s talks will also be streamed and recorded, but I don’t know what plans exist.
