As Matt recently noted, we both have a ton of photos from various expeditions that we’ve never got around to posting — not to mention a ton of specimens that we’ve seen but never got around to working on. Here is one of the most exciting:

As you can see, this is a massive cervical vertebra from a sauropod, probably a brachiosaurid, eroding right out of the ground. It’s in an undisclosed location in the Arches National Park, which we visited in May 2016. The neural arch is in amazingly good shape, though the end of the right prezygapophysis has broken off and been displaced slightly upwards. The postzygapophysesal facet is difficult to make out. Here’s a rough-and-ready interpretive drawing to get you oriented, with the completely missing parts speculatively sketched in light grey. (We don’t know how much more of this vertebra might be preserved underground.)

Apart from its size, the most striking thing about this vertebra is how very pneumatic it is — corroborating the long-standing hypothesis that pneumaticity tends to be positively allometric. If you compare with the much-loved 8th cervical vertebra of the Giraffatitan brancai paralectotype MB.R.2181 (formerly HMN SII), you can see similar “sculpted” features on the arch of that vertebra, but they are much less developed and ramified:

(This photo is in of course in left dorsolateral view, whereas the aspect of the Arches vertebra available to us is right lateral, and slightly ventral of true lateral.)

How big is the Arches vertebra? Stupidly, we didn’t have measuring equipment with us when we were visiting the park, so we don’t have an exact figure. But we can get some idea by extrapolating from the photo above. The stretched-out arm-span of an adult man is close to his height. I’m 1.8 m tall, so allowing for the downward slope of my arms, we might guess that the fingertip-to-fingertip measurement is about 1.7 m. If that’s right, measuring off the photo, the preserved portion of the vertebra is nearly twice that, at 3.3 m — and the complete length must have been somewhat longer, as the back end of the centrum is completely missing. Something in the region of 3.6 m might not be too far out. But as always, note that these are extremely speculative figures based on multiple layers of approximation.

We really need to get back out there, measure that thing properly, and of course try to find a way to have it excavated.

In the summer of 2015, Brian Engh and I stopped at the Copper Ridge dinosaur trackway on our way back from the field. The Copper Ridge site is 23 miles north of Moab, off US Highway 191. You can find a map, directions, and some basic information about the site in this brochure. The BLM has done a great job of making this and other Moab-area dinosaur trackways accessible to the public, with well-tended trails and nice interpretive signage. Brian has gotten to do the art for interp signs at several sites now, including Copper Ridge, and he put together this video to explain a bit about the site, what we know about the trackmaker, and the lines of evidence he used in making his life restoration. I’m in there, too, yammering a bit about which sauropod might have been responsible. We weren’t sure what, if anything, we would end up doing with the footage at the time, so I’m basically thinking out loud. But that’s mostly what I do here anyway, so I reckon you’ll live.

Stay tuned (to Brian’s paleoart channel) for Part 2, which will be about the Copper Ridge theropod trackway. And the next time you’re in the Moab area, go see some dinosaur tracks. This is our heritage, and it’s cool.

Last week I went to Halifax, Nova Scotia, for the twice-yearly meet-up with my Index Data colleagues. On the last day, four of us took a day-trip out to Peggy’s Cove to eat lunch at Ryer Lobsters.

We stopped off at the Peggy’s Cove lighthouse on the way, and spotted a vertebrate, which I am pleased to present:

mike-with-whale

It’s a whale skull, but I have no idea what kind. Can anyone help out?

So much for vertebrates — it was really all about the inverts. Here are six of them:

mike-with-lobster

I have a 2lb lobster here; my colleague Jakub went for two 1lb lobsters, as did Jason and Wolfram (not pictured). That’s Wolfram’s lobster closest to the camera, giving a better impression of just what awesome beasts these were.

Peggy’s Cove: recommended. For vertebrates and inverts.

(Thanks to Wolfram Schneider for these photos.)

 

Continuing our Brachiosaurus series [part 1part 2part 3part 4part 5part 6, part 7], here is another historically important photo scanned from the Glut encyclopaedia: this time, from Supplement 1 (2000), page 157.

Glut2000-p157--brachiosaurus-altithorax-quarry

This is the Brachiosaurus altithorax holotype FMNH P25107 in the field, at Grand Junction, Colorado, in 1900. Clearly visible are the seven presacral vertebrae running across the middle of the photo (upside-down, so we see their ventral surfaces), several ribs on either side, and the end of a long-bone to the left — most likely the distal end of the femur.  The flat bone at bottom left is probably part of the ilium, with the circular cut-out being the acetabulum. (The caption also mentions the sacrum, which I can’t see.)

As with the photo of the mounted skeleton in the museum, this is one of the Field Museum’s own photos — neg. #4027 — but I can’t find a better copy online. It’s got to be out there somewhere — can anyone help?

Actually we had the Jurassic talks today, but I can’t show you any of the slides*, so instead you’re getting some brief, sauropod-centric highlighs from the museum.

Like this Camarasaurus that greets visitors at the entrance.

And this Apatosaurus ilium ischium with bite marks on the distal end, indicating that a big Morrison theropod literally ate the butt of this dead apatosaur. Gnaw, dude, just gnaw.

And the shrine to Elmer S. Riggs.

One of Elmer’s field assistants apparently napping next to the humerus of the Brachiosaurus alithorax holotype. This may be the earliest photographic evidence of someone “pulling a Jensen“.

Cary and Matt with Brachiosaurus forelimb

Here’s the reconstructed forelimb of B. altithorax, with Cary Woodruff and me for scale. The humerus and coracoid (and maybe the sternal?) are cast from the B.a. holotype, the rest of the bits are either sculpted or filled in from Giraffatitan. The scap is very obviously Giraffatitan.

Matt with MWC Apatosaurus femur

Cary took this photo of me playing with a fiberglass 100% original bone Apatosaurus femur upstairs in the museum office, and he totally passed up the opportunity to push me down the stairs afterward. I kid, I kid–actually Cary and I get along just fine. It’s no secret that we disagree about some things, but we do so respectfully. Each of us expects to be vindicated by better data in the future, but there’s no reason we can’t hang out and jaw about sauropods in the meantime.

Finally, in the museum gift shop (which is quite lovely), I found this:

Dammit Nova

You had one job, Nova. ONE JOB!

So, this is a grossly inadequate post that barely scratches the surface of the flarkjillion or so cool exhibits at the museum. I only got about halfway through the sauropods, fer cryin’ out loud. If you ever get a chance to come, do it–you won’t be disappointed.

I need to be sleeping, not blogging, so here are just the highlights, with no touch-ups and minimal commentary.

I don’t know what these real street signs were doing sitting on the ground when I walked to the museum this morning, but it was a good omen for the conference.

Home base for this part of the conference. We head to Green River, Utah, on Friday for the Early Cretaceous half.

IMG_4505

I had never seen this on exhibit. This is not the Brachiosaurus scapulocoracoid formerly referred to “Ultrasauros”, this is the other big scap from Dry Mesa, from the giant diplodocid Supersaurus.

IMG_4982

Seems legit.

This is not Dinosaur Baptist Church–it is a cathedral of an entirely different order.

IMG_4545

And that order is Sauropoda.

IMG_4548

The sauropod bones are entombed in a matrix consisting of super-hard sandstone and non-sauropod bits.

I got about 150 photos of the Wall, but only because I ran out of time. You probably already know what I’m going to attempt with them. (If not, here’s a hint.)

Jim Kirkland (center left) literally walked us through the Morrison and Cedar Mountain Formations at this set of exposures north of the visitor center. The reddish stuff on the lower left is Morrison, and after that it’s CMF all the way up this ridge and next two behind it.

Yesterday I was at the Berlin 11 satellite conference for students and early-career researchers. It was a privilege to be part of a stellar line-up of speakers, including the likes of SPARC’s Heather Joseph, PLOS’s Cameron Neylon, and eLIFE’s Mark Patterson. But even more than these, there were two people who impressed me so much that I had to give in to my fannish tendencies and have photos taken with them. Here they are.

MikeTaylor-with-JackAndraka2

This is Jack Andraka, who at the age of fifteen invented a new test for pancreatic cancer that is 168 times faster, 1/26000 as expensive and 400 times more sensitive than the current diagnostic tests, and only takes five minutes to run.  Of course he’s grown up a bit since then — he’s sixteen now.

Right at the moment Jack’s not getting much science done because he’s sprinting from meeting to meeting. He came to us in Berlin literally straight from an audience with the Pope. He’s met Barack Obama in the oval office. And one of the main burdens of his talk is that he’s not such an outlier as he appears: there are lots of other brilliant kids out there who are capable of doing similarly groundbreaking work — if only they could get access to the published papers they need. (Jack was lucky: his parents are indulgent, and spent thousands of dollars on paywalled papers for him.)

Someone on Twitter noted that every single photo of Jack seems to show him, and the people he’s with, in thumbs-up pose. It’s true: and that is his infectious positivity at work. It’s energising as well as inspiring to be around him.

(Read Jack’s guest post at PLOS on Why Science Journal Paywalls Have to Go)

Here’s the other photo:

IMG_20131118_202834

This is Bernard Rentier, who is rector of the University of Liège. To put it bluntly, he is the boss of the whole darned university — an academic of the very senior variety that I never meet; and of the vintage that, to put it kindly, can have a tendency to be rather conservative in approach, and cautious about open access.

With Bernard, not a bit of it. He has instituted a superb open-access policy at Liège — one that is now being taken up as the model for the whole of Belgium. Whenever members of the Liège faculty apply for anything — office space, promotions, grants, tenure — their case is evaluated by taking into account only publications that have been deposited in the university’s open-access repository, ORBi.

Needless to say, the compliance rate is superb — essentially 100% since the policy came in. As a result, Liège’s work is more widely used, cited, reused, replicated, rebutted and generally put to work. The world benefits, and the university benefits.

Bernard is a spectacular example of someone in a position of great power using that power for good. Meanwhile, at the other end of scale, Jack is someone who — one would have thought — had no power at all. But in part because of work made available through the influence of people like Bernard, it turned out he had the power to make a medical breakthrough.

I came away from the satellite meeting very excited — in fact, by nearly all the presentations and discussions, but most especially by the range represented by Jack and Bernard. People at both ends of their careers; both of them not only promoting open access, but also doing wonderful things with it.

There’s no case against open access, and there never has been. But shifting the inertia of long-established traditions and protocols requires enormous activation energy. With advocates like Jack and Bernard, we’re generating that energy.

Onward and upward!
