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!

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!

Damn, Wedel, you really let yourself go.

I love Utah. I love how much of the state is given over to exposed Mesozoic rocks. I love driving through Utah, which has a strong baseline of beautiful scenery that is frequently punctuated by the absolutely mind-blowing (Arches, Bryce Canyon, Zion, Monument Valley…). I love doing fieldwork there, and I love the museums, of which there are many. It is not going too far to say that much of what I learned firsthand about sauropod morphology, I learned in Utah (the Carnegie Museum runs a close second on the dragging-Matt-out-of-ignorance scale).
There is no easy way to say this so I’m just going to get it over with: Mike has never been to Utah.
I know, right?
But we’re going to fix that. Mike’s flying into Salt Lake City this Wednesday, May 4, and I’m driving up from SoCal to meet him. After that we’re going to spend the next 10 days driving around Utah and western Colorado hitting museums and dinosaur sites. We’re calling it the Sauropocalypse.
Why am I telling you this, other than to inspire crippling jealousy?
First, Mike and I are giving a pair of public talks next Friday evening, May 6, at the USU-Eastern Prehistoric Museum in Price. The talks start at 7:00 and will probably run until 8:00 or shortly after, and there will be a reception with snacks afterward. Mike’s talk will be, “Why giraffes have such short necks”, and my own will be, “Why elephants are so small”.
Second, occasionally people leave comments to the effect of, “Hey, if you’re ever passing through X, give me a shout.” I haven’t kept track of all of those, so this is me doing the same thing in reverse. Here’s our itinerary as of right now:
May 4, Weds: MPT flies in. MJW drives up from Cali. Stay in SLC/Provo area.
May 5, Thurs: recon BYU collections in Provo. Stay in SLC/Provo area.
May 6, Fri: drive to Price, visit USU-Eastern Prehistoric Museum, give evening talks. Stay in Price.
May 7, Sat: drive to Vernal, visit DNM. Stay in Vernal.
May 8, Sun: visit Utah Field House, revisit DNM if needed, drive to Fruita.
May 9, Mon: visit Rabbit Valley camarasaur in AM, visit Dinosaur Journey museum in PM. Go on to Moab.
May 10, Tues: drive back to Provo, visit BYU collections.
May 11, Weds: BYU collections.
May 12, Thurs: drive to SLC to visit UMNH collections, stay for Utah Friends of Paleontology meeting that evening.
May 13, Fri: BYU collections.
May 14, Sat: visit North American Museum of Ancient Life. MPT flies home. MJW starts drive home.
We’re planning lots of time at BYU because we’ll need it, the quantity and quality of sauropod material they have there is ridiculous. As for the rest, some of those details may change on the fly but that’s the basic plan. Maybe we’ll see you out there.
Here at SV-POW! Towers, we’re keenly aware that some of our fans are just here for the hardcore sauropod vertebra action. These folks start to shift in their seats when we put up too many posts in a row on open access or rabbits or…okay, mostly just OA and bunnies. If that’s you – or, heck, even if it isn’t – your good day has come. Saddle up. Let’s ride.
When Brian Engh and I were at the new Natural History Museum of Utah recently, I spotted this cute little juvenile cervical in one of the display cases.
According to this sign, it’s UMNH 21054, and it was found by Frank DeCourten and prepared by Virginia Tidwell.
It shares a display case and a sign with what is probably an anterior dorsal, UMNH 21055.
Now, I don’t mean to brag (okay, maybe a little…) but the number of EKNApod* vertebrae is not large and the number of EKNApod vertebrae I’m not intimately familiar with hovers near zero. This thing was ringing bells – I knew I’d seen it before.
* Early Cretaceous North American sauropod
Here are few more views. Note the light-colored oblong spot on the top of the condyle in the image above – this may be a pneumatic foramen filled with matrix, or a spot where the cortical bone flaked away to reveal one of the internal pneumatic spaces. Also, check out the fragment of extraneous bone (probably cervical rib) stuck sideways across the top of the centrum, just behind the condyle, in the image immediately below. Both of these features will be important later.
The vert belongs to a juvenile sauropod because the neural arch is missing – it didn’t fuse to the centrum before the animal died. But it was a big baby; the centrum is maybe just a hair under 40 cm in length, meaning that a world-record giraffe might just maybe have a couple of cervicals of the same length. But basal titanosauriforms typically have 12-13 cervicals, not the whimpy 7 that almost all mammals must make do with, and all-stars like Euhelopus can have up to 17.
Also, this was not from the middle of the neck. No way. The parapophyses are huge, and the centrum is pretty stubby compared to Sauroposeidon or YPM 5294, the Sauroposeidonesque cervical from Unit VII of the Cloverly (pic here). My guess is we’re looking at something past the middle of the neck, where the cervicals start to get proportionally shorter (but sometimes max out in absolute length), maybe a C9 or C10. In Giraffatitan brancai HM SII/MB.R.2181, C10 has a centrum length of 100 cm and makes up about 12% of the 8.5-meter neck. Assuming similar proportions here, UMNH 21054 came from the roughly 3-meter neck of a sauropod about the size of a really big draft horse or a really small elephant.
But enough noodling about the animal’s size. I knew I’d seen this vert before, but where? Thank goodness for comprehensive signage – I knew the material had been discovered by Frank DeCourten and prepped by Virginia Tidwell. At one of the SVP meetings in Denver, at a reception at the Denver museum, Virginia had invited me into the prep lab to see some EKNApod material from the Long Walk Quarry in Utah. The Long Walk Quarry was Frank DeCourten’s baby – he wrote a couple of papers about it (e.g., DeCourten 1991) and included additional information in his book, Dinosaurs of Utah (1998; second edition in 2013). DeCourten had referred the material to Pleurocoelus because that’s what people did with EKNApods back in the 20th century, but I remembered seeing one cervical that, like Sauroposeidon and YPM 5294, was just too long to match any of the Pleurocoelus material. My ‘Museum Photos’ file has a subfolder titled ‘Denver 2004’ – was the mystery vert in there?
In short, yes. Here’s one of the photos I took back in 1994.
Here’s another, sans flash this time. Check out the white spot on top of the condyle, the bar of float bone stuck sideways across the centrum just behind the spot, and general pattern of breaks – it’s a perfect match for UMNH 21054. Also note the block number on the pink specimen label at the bottom of the image – LWQ8, for Long Walk Quarry.
Three mysteries remain. One, the signage says the vert is from Carbon County, Utah, but the Long Walk Quarry has always been described as being in Emery County. Just a typo, or is there a story there? Two, how much of the animal (or animals) was excavated and prepped? I saw other vertebrae, both larger and smaller, when I was in Denver back on ’04, and DeCourten figured still others that I haven’t yet seen personally. Finally, is anyone working on it? And if not…[cautiously raises hand].

Now that, faithful readers, is a monument to evolution and its endless forms most beautiful. I’m talking about the wall of ceratopsian skulls at NHMU, of course, not the back of Brian Engh’s head (bottom center).
If you don’t know them all on sight (yet!), here’s a cheat sheet. I goofed on a couple myself: before I looked at the sheet I figured Coahuilaceratops as Pentaceratops and mistook Kosmoceratops for Vagaceratops. Still, 12 out of 14 isn’t bad for a minor-league ceratopsian scholar such as yours truly.
Here’s the chasmosaurine-centric view from lower right.
And the centrosaurine-centric view from distant left.
The world needs more things like this. Good on ya, NHMU.
