Unworn:

Worn:

Spent some time last week just admiring these things. They’re pretty cool.

EDIT: in answer to Mike’s question in the first comment below, here’s a photo of some more worn teeth, showing that the level of wear in the one shown above is not unusual. Also, all of these worn teeth still had full roots, with no sign of the root resorption that would have preceded shedding of the tooth, so they were evidently going to be used for a while yet, probably a few months at least — BUT see the very useful comment from Jens Kosch below on the likely rapidity of tooth replacement in Camarasaurus.

DINO collections - more worn Camarasaurus teeth

Here’s a piece of signage from the wonderful Dinosaur National Monument, which we visited on the 2016 Sauropocalypse.

And in close-up:

This is the first and only time I’ve been encouraged to touch real dinosaur bones on the basis that a cast of them was too fragile.

Happily, we did have some great experiences with the actual fossils. Here is Matt, inspecting part of the wall, while our host Dan Chure documents the moment and the cotyle of a convenient ?Camarasaurus cervical acts as a receptacle for the cameras not in use at that point.

Above us, on the balcony, tourists wonder at such astonishingly massive creatures, and their ability to navigate a wall of fossils.

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

Mike, astonished by a particularly extreme apatosaur cervical. But then aren’t they all extreme?

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

Barosaurus, an Allosaurus adult and several juveniles, and Mike.

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

Matt is attacked by a Utahraptor, but is all like “Am I bovvered?”. To be honest, I suspect he was all dinosaured out by this 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!

Not much to say this time – the pictures tell the story for now.

It was a pretty transcendental experience, as I imagine it must be for anyone who loves dinosaurs, or has a pulse.

A huge thank-you to Dan Chure, the Park Paleontologist for the Monument, who conveyed us safely up and down the Wall, taught us about the prehistory of the site and the human history of its excavation and conservation, held scale bars, moved backpacks, took photos, and generally seemed to be having just as much fun as we were. This has been a common theme on the trip – every single person we’ve interacted with at a museum or fossil site has been unfailingly welcoming and generous with their time and knowledge. Whatever challenges vert paleo faces, a lack of wonderful people is not one of them.

I was up there, too, for the second time in my life – that will be a post for another day. For now, just bask in the glory of Mike basking in the glory of a literally mind-numbing array of amazing fossils.

Utah Field House Diplodocus 1

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.
