I got an email this morning from Jim Kirkland, announcing:
All of the lectures (with permission to be filmed) will be available on the NHMU YouTube channel. I just wrapped the edit of the 6th video which should be available later today. However, 5 of the lectures are now edited and already available for viewing. They can be found here.
And by the time I read that message, the sixth talk had appeared!
Each talk is 20-25 minutes long, so there’s a good two and a quarter hours of solid but accessible science here, freely available to anyone who wants to watch them. Here, to get you started, is long-time friend of SV-POW!, Randy Irmis, on Discovering Dinosaur Origins in Utah:
It’s great that the DinoFest people are doing this. In 2017, it should really be the default — and yet I can’t think of a single vertebrate palaeo conference that has done this before. (Did I miss some? Links, please!)
I know it’s one more thing for conference organisers to have to think about (or, more optimistically, one more thing for them to delegate). but I hope we’ll be seeing a lot more of it!

I’m back in Oklahoma for the holidays, and anytime I’m near Norman I pop in to the OMNH to see old friends, both living and fossil. Here’s the Aquilops display in the hall of ancient life, which has been up for a while now. I got some pictures of it when I was here back in March, just never got around to posting them.
Aquilops close up. You can’t see it well in this pic, but on the upper right is a cast of the Aquilops cranium with a prosthesis that shows what the missing bits would have looked like. That prosthesis was sculpted by – who else? – Kyle Davies, the OMNH head preparator and general sculpting/molding/casting sorceror. You’ve seen his work on the baby apatosaur in this post. I have casts of everything shown here – original fossil, fossil-plus-prosthesis, and reconstructed 3D skull – and I should post on them. Something to do in the new year.
The Aquilops display is set just opposite the Antlers Formation exhibit, which has a family of Tenontosaurus being menaced by two Deinonychus, and at the transition between Early and Late Cretaceous. The one mount in the Late Cretaceous area is the big Pentaceratops, which is one of the best things in this or any museum.
Evidence in support of that assertion. Standing directly in front of this monster is a breathtaking experience, which I highly recommend to everyone.
It’s just perfect that you can see the smallest and earliest (at least for now) North American ceratopsian adjacent to one of the largest and latest. Evolution, baby!
I didn’t only look at dinosaurs – the life-size bronze mammoth in the south rotunda is always worth a visit, especially in holiday regalia.
No holiday post about the OMNH would be complete without a shot of “Santaposeidon” (previously seen here). I will never get tired of this!
The chances that I’ll get anything else posted in 2016 hover near zero, so I hope you all have a safe and happy holiday season and a wonderful New Year.

Oh man, 2016, you are really working on my nerves.
Sometimes it’s a positive balm to hold a piece of an animal dead and gone for 145 million years, or stare at a thousand vertical feet of sandstone, and know that we are all ants.
These lovelies here intrigue me deeply. They’re the three caudal vertebrae recovered from the Snowmass Haplocanthosaurus that John Foster and I described a couple of years ago. Pretty sure I’ll have more to say about them in the future. For now it’s enough that they’ve come across such a vast gulf of time and given this stressed-out primate a little perspective.
Foster, J.R., and Wedel, M.J. 2014. Haplocanthosaurus (Saurischia: Sauropoda) from the lower Morrison Formation (Upper Jurassic) near Snowmass, Colorado. Volumina Jurassica 12(2): 197–210. DOI: 10.5604/17313708 .1130144

Back when I started writing about issues in scholarly publishing, I would sometimes write about the distinction between for-profit (bad) and non-profit (good) publishers. While I still recognise this as an issue, thinking it through over the last few years has made it clear that this distinction is largely orthogonal to the one that really matters — which is between open and non-open publishers.
In fact, all four quadrants exist:
ACS may be a 501(c)(3) nonprofit organization, and PeerJ may be a private company primarily owned by two individuals — but it’s PeerJ that’s pushing openness forward, and ACS doing quite the opposite.
I’ve found myself thinking about this recently for two reasons.
The first is that, like anyone who works on sauropods, I’ve had involvement with specimens at the Sauriermuseum Aathal (SMA), a privately owned museum in Switzerland that holds some astonishingly beautiful and complete specimens, including the Kaatedocus holotype, SMA 0009. In particular, I’ve been invited a few times to peer-review manuscripts describing SMA specimens, and I’ve always felt conflicted about this because of the SVP’s strong position on privately held specimens.
The second thing that’s pushed me to rethink the private-public distinction has been working on Barosaurus. Our experiences with specimens have been varied. Yale University was very helpful when we went to see the holotype YPM 429, and BYU really couldn’t have done more for us on our recent visit. This is what we would hope for, of course. But what we didn’t particularly anticipate is how generous and helpful the people at the commercial fossil hunters Western Paleo Labs would be. When, visiting the North American Museum of Ancient Life, we gazed in awe through their prep. lab window at their several gorgeous Barosaurus cervicals (see photo above), they invited us in to play with them. (The vertebrae, not the people.)
And that made me think about our much less satisfactory experience trying to photograph the presacrals of AMNH 6341 at the American Museum of Natural History — they are entombed in a glass case surmounted by a not-really-transparent walkway:
Which meant that, when trying to obtain dorsal-view photographs, I had to use this technique:
With results like these:
Now I want to be clear that everyone we dealt with at the AMNH was as helpful as they could be. No-one that we met there was in any way obstructive. Yet the fact remains, the crucially important presacral verterbrae of the most widely recognised Barosaurus in the world were essentially impossible to study.
Worse: papers that have been published about those specimens are now essentially irreproducible, because the specimens are not really available for re-study — much as though they’d been sold to Nicolas Cage to display over his mantelpiece.
Whereas the Barosaurus vertebrae at Western Paleo Labs do seem to be available for study.
Just as we were mistaken in focussing primarily on the for-profit/non-profit distinction between publishers when what we really cared about was the open/non-open distinction, could it be that we’ve been misfocussing on the public/private ownership distinction when what we really care about is availability of specimens?
Is there a way to be confident about which museums will and will not always make specifimens available for study? Here’s where my knowledge cuts out, but one would think this would be the key element in museum certification. But then no doubt museum certification is done differently in different jurisdictions. Knowing that a German museum is accredited may tell you something completely different from knowing that an America museum is accredited.
So perhaps what we need is some globally recognised statement that any museum in the world can sign up to: formally committing to keep its specimens available to researchers; and comitting never to sell them to any party that has not also signed up to the statement.
It’s worth noting the Sauriermuseum Aathal seems, as far as I’ve ever heard, to have conducted itself in every way as we would wish. They seem pretty unambiguously to be among the good guys. More: they seem to have unilaterally done more or less what I advocated above: their website declares:
Declaration Concern: Holotypes of the fossil-collection of the Sauriermuseum Aathal.
The Sauriermuseum Aathal, Switzerland (SMA), is being recognized more and more as valuable scientific institution. We hereby state publicly the SMA policy concerning holotype specimens. We recognize the importance of these reference specimens for science, and strongly agree that they have to be available for science in perpetuity. Therefore, we declare that all holotypes present at the Sauriermuseum Aathal, Switzerland (and all new holotypes that will be described in future), will always be publicly accessible to all bona fide researchers, and will never be allowed to be sold to any private collection.
Are they one step ahead of us? And if so, should we cast off our reservations about publishing on their specimens?

Suppose that I and Matt were right in our SVPCA talk this year, and the
“Supersaurus” cervical BYU 9024 really is the C9 of a gigantic Barosaurus. As we noted in our abstract, its total length of 1370 mm is exactly twice that of the C9 in AMNH 6341, which suggests its neck was twice as long over all — not 8.5 m but 17 m.
How horrifying is that?
I realised one good way to picture it is next to the entire mounted skeleton of Giraffatitan at the Museum für Naturkunde Berlin. That skeleton is 13.27 m tall. At 17 m, the giant barosaur neck would be 28% longer than the total height Giraffatitan.
Yes, this looks ridiculous. But it’s what the numbers tell us. Measure the skeleton’s height and the neck length off the image yourself if you don’t believe me.
(Note, too, that the size of the C9 in that big neck is about right, compared with a previous scaled image that Matt prepared, showing the “Supersaurus” vertebra in isolation alongside the Chicago Brachiosaurus.)

Here is a vertebra that Matt and I saw on our recent travels through Utah:
I will explain in a subsequent post where we saw it, who gave us access, where and when it is from, and so on.
For now, I want people’s gut reactions: what is it?
May 18, 2016
As regular readers will know, Matt and I have recently spent ten glorious days travelling the dinosaur museums of Utah, in a once-in-a-lifetime event that we have been calling the Sauropocalypse. In that time, we visited seven different museums and — this is the truth — had an absolutely fantastic time in all of them. One of the big reasons is of course the quality of their collections and galleries. But equally important is the welcome we got from our hosts at each of these places, and the help they all generously and cheerfully gave us.
Here’s where we visited, in chronological order, with a word of thanks to each host.
1. BYU Museum of Paleontology, Provo
At the amazing BYU — where we spent three full days, as it has almost certainly the largest collection of sauropod fossils anywhere in the world — our host was Brooks Britt. (Matt’s mentioned Brooks previously on this blog, as one of the most formative influences on his career: the person who put him onto pneumaticity.)
Brooks set us free in his collections and gallery with no restrictions. He had specimens fork-lifted down from high shelves for us, gave us a pallet lifter so we could move them around at will, and generally did everything he could to make our stay productive. He also took us out to lunch, twice: once at a cheap but delicious taco place, and once at a Brazilian eat-all-you-want barbecue place where I could happily have spent the entire afternoon.
2. The Prehistoric Museum, Price
Our host at Price was occasional SV-POW! commenter Ken Carpenter, who also arranged for us to give a pair of talks at the museum in the evening. (Mine: Why giraffes have short necks. Matt’s: Why elephants are so small.) Ken gave us free reign to get in among the exhibits, and we took full advantage to make a potentially important discovery (to be discussed in a future post).
Ken also took us to see the CEUM collections, and invited us to take on a huge descriptive project, working on the PR2 brachiosaur. Sadly, that project is just too big for either of us. But there are individual elements within the PR2 collection that are of interest, and no doubt we’ll be posting more about those, too.
3. Dinosaur National Monument, Jensen
Matt has already paid tribute to Dan Chure, our host up on the wall, who came in on his day off just to help us. An extraordinary host at an astonishing venue.
4. Utah Field House of Natural History, Vernal
Here, we were hosted by Mary Beth Bottomley. She went beyond the call of duty in not only allowing us access to the prep room and collections, but helping us to take apart the shelving in collections so we could get better photos of a big, difficult-to-move specimen. Mary Beth was particularly interested in what we were working on, and will (I hope) now be a regular reader of this blog.
5. Dinosaur Journey, Fruita
We were, inadvertently, sensationally rude to our host, Julia McHugh. She’d arranged to take us for lunch, but Matt was so obsessed with the transit of Mercury across the sun that he completely forgot, and sent me off to get salads from Subway instead. (Note that I am making the point here that Matt forgot this arrangement. I make no comment on my own recall.) As a result, we cheated ourselves out of a BBQ lunch.
But Julia was great about it, and once again we were given free reign in collections. Matt and I were each able to make valuable observations, one for an already-in-progress paper and one for a new one.
6. Natural History Museum of Utah, Salt Lake City
Here, our host was Carrie Levitt. She welcomed us to the museum, gave us a tour of collections, left us to it, and … we spent almost the entire day in the public gallery instead! I did get a couple of nice photos of the holotype skulls of Kosmoceratops and Diabloceratops, but the truth is that the public gallery was so awesome, it just sucked us in.
But Carrie was great about it. Rather than resenting our having wasted her time in the collections orientation, she was just glad that we got useful observations out of the museum. (And we did. Matt and I can sometimes get so wrapped up in individual vertebrae that we forget they’re part of whole animals. The many fine mounted dinosaur skeletons at UMNH helped to redress this failing.)
7. North American Museum of Ancient Life, Thanksgiving Point
On our last day — I had to be at the airport by 6pm — we went to NAMAL, We’d not been able to make contact with staff ahead of time, as Matt’s old contact seems to be no longer at the museum. But as we walked past the prep lab near the museum entrance, we saw some beautiful Barosaurus cervicals. As we stood gawping, Rick Hunter, inside the lab, recognised Matt and invited us in.
With no prior notice at all, Rick dropped what he was doing to help us out as we inspected their gorgeous material. That’s been really helpful as we’ve firmed up our ideas on what Barosaurus is. (And I hope we’ve helped them get a better handle on the serial positions of their vertebrae, too.)
In summary, pretty much everyone we met in Utah was super-helpful and super-nice. That also includes John and ReBecca Foster, who put us up for the night in Moab, the night before we went to Arches National Park. The people are one of three reasons why Utah is now my favourite US state. (The others are the sauropods, naturally, and the landscapes.)
Museum folks of Utah, we salute you!
