Fossil resources under threat, a volcanic trailer, two new theropods, and a tweeting tyrannosaur. It’s all in today’s Gratuitous Dinosaur Post.ITEM THE FIRST: You’ve probably heard about the Trump administration’s move to slash land away from Bears Ears National Monument and Grand Staircase-National Monument. What you may not know is that the two sites are paleontological treasure troves. In fact, their spectacular fossil resources helped get them established as national monuments in the first place.
Trump’s decision puts a lot of scientific data in jeopardy, so the Society of Vertebrate Paleontology is taking the administration to court to try and stop it. SVP President P. David Polly explains why this lawsuit is necessary:
When Grand Staircase-Escalante was set aside, there were very few areas anywhere in the world where we had a mammal fossil record right at the late Cretaceous period, when different mammal groups were diverging. Those fossils really filled a gap in mammal paleontology and put Grand Staircase on the map from a paleontological point of view. We now have the most extraordinary Late Cretaceous ecosystem documented anywhere. After the monument was established, a lot of the dinosaur material was discovered.
In Bears Ears, the very oldest and the very youngest fossils have been excluded, including one area that documents the transition from amphibians to true reptiles. In Grand Staircase, they’ve hacked off most of the very southern edge of the monument and the very eastern edge. That cuts out a really important interval in time, including the world’s greatest mass extinction, and the Triassic period, which is really when life started re-evolving again. Some of the mammal-bearing units I just described are out in their entirety. One of the great ironies is that the original localities where all the great discoveries were made in the 1980s and 1990s, which led to the founding of the monument, are now out of the monument.
[But on BLM lands managed for multiple uses,] if there’s another competing use the paleontology does not necessarily hold sway. An extreme example would be mining—if mining wins out, then the fossils can be destroyed. Second, the monument is better staffed, so it’s harder for someone to sneak in illegally and take things, whereas on ordinary BLM land it’s much less well policed.
Third, in national monuments where paleontology is one of the designated resources, there’s a whole special funding stream for research. A lot of the work that has been done at Grand Staircase has essentially been a public-private partnership. The funding through the monument has really made the science there blossom; we would not have seen the level or number of finds there over the last 20 years had that not existed.
ITEM THE SECOND: Now, how ’bout that Fallen Kingdom trailer?
As far as first trailers go, I like this one a lot better than Jurassic World‘s. JW‘s trailer, I think, gave away a bit too much. Revealing the helicopter crash in the aviary was especially unfortunate. It undercut a lot of the shock we should’ve felt at Masrani’s death.
One thing the trailer does reveal is a ginormous volcanic eruption that triggers a dinosaur stampede. This prehistoric plot trope dates back to the very dawn of dino movies, having been depicted in the 1925 adaptation of Sir Arthur Conan Doyle’s The Lost World. But I don’t think it’s ever been done as impressively as this.
The Baryonyx at 00:58 has been generating most of the buzz on the Interwebs, but I’m especially glad to see Carnotaurus finally making its debut in the film series. Crichton featured this genus in the second novel, so it’s high time it showed up in the movies.
Fans have also been speculating about the identity of that carnivore at 1:51. It looks a lot like an Allosaurus. As a longtime allo fan, I’d love to see it in a JP movie, but it does seem a little odd to add such a standard carnosaur to a film franchise that already has quite a few big meat-eaters. With so many weird theropods out there, you’d think they’d want to showcase some of the more offbeat ones. Then again, since Allosaurus fossils are plentiful, I suppose it’s as likely to turn up in a dinosaur theme park as any other big predator.
ITEM THE THIRD: Halszkaraptor, the newly christened, semi-aquatic theropod from Mongolia, had a goose’s neck, a raptor’s claws, and a snout full of sensors like a crocodile’s. Convergent evolution is a heck of a thing.
ITEM THE FOURTH: One of the most famous fossils in Haarlem’s Teylers Museum is getting a new name…again. In 1970, while examining the museum’s pterosaur collection, John Ostrom determined that its type specimen of Pterodactylus crassipes wasn’t a pterodactyl at all, but an Archaeopteryx. Now a team of researchers has identified the Teylers fossil as a new genus of dinosaur, which they’ve named Ostromia crassipes.
ITEM THE FIFTH: Chicago magazine caught up with Sue, the Field Museum’s resident T. rex, to talk about social media and how she’ll be spending her downtime as she awaits her move to a new gallery:
There may be some behind-the-scenes hijinks while I’m off display getting ready to be remounted. As a (temporarily) disembodied rage emu, I can roam the halls and maybe check in on the new 122-foot-long sauropod playing door greeter. That is, if it can ever shut up about “going vegan.” WE GET IT YOU EAT KALE [leaf emoji].
Also, did you know less than 1 percent of The Field Museum’s collections are on public display? With some free time on my tiny, but powerful, hands I will finally be able to see EVERY rove beetle we have. And buddy…DEMS A LOT OF ROVE BEETLES.
