TMNT Turtles in Time cover

So, this is on the shelves right now. Underage anthropomorphic martial chelonian cargo notwithstanding, the Triceratops on the cover is pretty standard.

TMNH Turtles in Time hell yeah Triceratops

The one on the inside is much less so. Or, at least it would have been up until a couple of years ago. Apparently, dinos that are All-Yesterdays-ed out are a pop culture Thing now.

TMNT Turtles in Time hell yeah T-rex

I’m quite taken with this decidedly un-shrink-wrapped T. rex. But then I would be, wouldn’t I? He’s a big guy with a beard who’s interested in turtles–he’s about one spatial dimension away from being me.

So anyway, if you dig on dinos, you might want to pick this one up. Kudos to cover artist David Petersen for rocking it old school, and to interior artist Ross Campbell for going next-gen.

Immediate Update: Arf, about 60 seconds after hitting “publish”, I realized that those rascals at Love in the Time of Chasmosaurs had gotten here first. Go read their much better post, and then kiss your productive time away as you get sucked into whatever cool stuff they’ve been posting on lately. Seriously, be careful over there.

Emeus crassus mount

In a back room at the Field Museum, from my visit in 2012.

I took a lot of photos of the neck, which nicely records the transition in neural spine shape from simple to bifurcated–a topic of interest to sauropodophiles.

Emeus crassus neural spines

On Monday we visited the Prehistoric Museum in Price, Utah, the Cleveland-Lloyed dinosaur quarry, and sites in the Mussentuchit member of the Cedar Mountain Formation. Many thanks to Marc Jones for the photos.

1 - CEU Prehistoric Museum

In 2010, the College of Eastern Utah became Utah State University – Eastern, and the CEU Prehistoric Museum in Price is now officially the USU Eastern Prehistoric Museum. The dinosaurs in the center of exhibit hall are being remounted. These include Allosaurus, Stegosaurus, Camptosaurus (mounted, toward top of photo), and Camarasaurus (dismounted, on floor). Most of the mounts are either real material or casts of real material from the nearby Cleveland-Lloyd quarry.

The museum has many other exhibits besides the one shown above. The paleo wing alone covers two floors, and upstairs there are great displays on Cretaceous dinosaurs from the area, including Jurassic and Cretaceous ankylosaurs, a ceratopsian, and numerous tracks.

2 - Cleveland-Lloyd orientation

After leaving Price we went to the Cleveland-Lloyd dinosaur quarry, which has produced over 20,000 separate elements, including the remains of something like 50-60 allosaurs. The smallest ones are hatchlings–several elements from literally cat-sized baby allosaurs are known from the quarry.

3 - Mark Loewen teaching

Mark Loewen (right) talked to us about how the quarry might have formed, and what it’s like to work there. On the left in the above photo you can see a bunch of disarticulated Allosaurus bones suspended above the floor on wires. These are placed to give an idea of the three-dimensional jumbling of the bones in the matrix. It is almost impossible to jacket one bone or even several without hitting others. I remember how that goes from working at the OMNH sauropod bonebed in the Cloverly–it’s almost impossible to avoid blowing through some bones just to get others out of the ground.

4 - Camarasaurus pelvis with bite marks

Here’s one of a handful of bones from the quarry with bite marks. This is the pelvis of a Camarasaurus, lying upside down, anterior toward the wall. The back end of the right ilium is heavily tooth-marked.

After Cleveland-Lloyd we stopped at a couple of sites in the Mussentuchit. I’m not going to blog about those because they are active sites that are still producing fossils. Unfortunately it is not uncommon for fossil localities on public land to be looted and vandalized by unscrupulous private collectors. I don’t want to give those a-holes any help, so I’ve deliberately not shown any photos of about half a dozen of the most interesting sites that we visited during the conference. It sucks to know cool things and not be able to tell people about them, but if I blab then I put those cool things at risk. Happily there is a lot of active research going on, including one or two projects that got hatched at this conference, so hopefully I will be able to tell some of these stories soon.

5 - MMFC14 conveners Jim Rebecca and John

Instead, I will close this series (for now) with a shout-out to the people who convened and ran the field conference: Jim Kirkland (left) and ReBecca Hunt-Foster (middle). John Foster (right) also contributed a lot of time, energy, effort, and expertise.

Jim Kirkland is amazing. If you know him, you know that his heart is as big and outgoing as his booming voice. His knowledge of and enthusiasm for the mid-Mesozoic sites in western Colorado and eastern Utah have driven a lot of science over the past quarter century, and he shared that knowledge and enthusiasm compulsively on this trip. My head is so full of new stuff, it’s honestly hard to think. I wish I had a solid week to just digest everything I learned at the conference.

My highest praise and thanks go to ReBecca. Thanks to her hard work and organization, the whole field conference ran about as much like clockwork as something this complicated can–and when it didn’t run smoothly, like that flat tire on Saturday, she took charge and got us back on track. She was basically den mom to about 60 folks, from teenagers to retirees, from at least ten countries and four continents, and somehow she did it all with unflagging grace and good humor. The fact that she had her appendix out just two or three days before the start of the conference only cements my admiration for what she pulled off here.

I had a fantastic time. I hope they do another one.

A short post this time, partly because it’s late, partly because the hotel internet is sucking bigtime–probably as the hotels fill up for the weekend. I simply don’t have the bandwidth to post more, and in fact I had to downsize these few photos to get them to upload in polynomial time.

Today we left Fruita, Colorado, and hit several Lower Cretaceous sites in eastern Utah on our way to Green River, Utah. Highlights were the Copper Ridge and Mill Canyon dinosaur tracksites.

Copper Ridge theropod and sauropod - 1200

Here’s a tridactyl theropod track between two sauropod pes prints at Copper Ridge.

Mill Canyon small therpod track - 1200

Here’s a little theropod track at Mill Canyon…

Mill Canyon large therpod track - 1200

…a big one…

Mill Canyon Dromaeosauripus - 1200

…and one that I had never seen before in person: Dromaeosauripus, the two-toed ichnogenus left by dromaeosaurs. Utahraptor or a close relative is a likely culprit for the Mill Canyon Dromaeosauripus.

Aitor Ederra drew my attention to this painting by Frederik Spindler:

86e63b799a

It’s briefly discussed in a blog-post on changing norms in palaeo-art. (I think the blog is Spindler’s, but I can’t find confirmation — its About page is singularly uninformative.)

As so often when we look at All Yesterdays-style palaeo-art, the initial reaction is “no way!”, but that’s quickly followed by a more thoughtful “… but why not?”

Well, why not? We have bare-skinned African and Asian elephants, but not so long ago we had wooly mammoths. Even assuming that Giraffatitan was as naked as Loxodonta, why would its polar equivalents not have adapted the ancestral dinofuzz into a thick insulating coat?
