GDP: The Smithsonian fossils are back, and better than ever

One of the perks of my job is an annual trip to DC for the celebration of Lincoln’s birthday on the National Mall.  Every year, I make a point to visit the National Museum of Natural History.

It was the first big natural history museum I ever visited as a child, and may very well be the place that first turned me into a museum junkie.  But it’s been years since I was able to see my favorite part of the NMNH—the dinosaur hall on the first floor.  The fossil exhibits have been closed for renovation since 2014.

Last week marked the first time I’ve been to DC since it reopened.  I was both excited and nervous.  As I’ve said before, the idea of this renovation was a bittersweet thing for me.  I was thrilled at the thought of an updated exhibit, but I was also afraid I’d miss the old mounts.  And I was especially worried I’d miss the dinosaur dioramas at the back of the hall.

I shouldn’t have worried.  The new exhibit Deep Time is nothing short of magnificent.  It combines everything that was great about the old hall with beautifully updated mounts, the latest science, and the finest in both modern and old-fashioned exhibitry.

Chronologically, Deep Time is about as comprehensive as it gets, from the emergence of life all the way up to the first human migrations and the extinction of the Ice Age megafauna, with hundreds of specimens along the way.

But let’s start with that T. rex.  Hoo boy!

My tastes tend to be pretty conventional when it comes to T. rex mounts.  I usually prefer your standard pose, with the animal in a simple striding position, head raised up to show off its height.  When I heard about the plan for the Nation’s T. rex—one foot planted on a Triceratops carcass, the neck and skull craning down to wrench its prey’s head off by the frill—I had my doubts.

But as soon as I stood in front of it, the NMNH’s mount instantly became my favorite T. rex display anywhere.

I don’t know why, but the whole creature just seems a lot more massive and powerful when you see it in this position.  Maybe it’s because the skull is closer to eye level.  Come to think of it, when Henry Fairfield Osborn planned the first-ever full T.rex mount at the American Museum of Natural History more than a century ago, he initially wanted to have two of them crouched over a carcass, with those big skull and hip bones down where visitors could get a good look at them.

This pose also allows you to examine the head from different angles.  You can really see the cranium shape that is so characteristic of tyrannosaurs—wider at the back, and then narrowing toward the snout.

I was under the impression that NMNH was going to attach the original skull to the mount, but a docent informed me that this is a copy.  Still looks pretty awesome.  And a lot of the bones in the photo below are the genuine article.

Diplodocus is still there, although no longer the centerpiece of the hall as it once was.  The new layout is a tremendous improvement.  You can get much closer to a lot of the big specimens now than you could in the old hall.

Stegosaurus and Ceratosaurs are back, too.  Now they’re engaged in combat, and it looks like the carnivore’s getting the worst of it.  Check out that patch of  armor on the stego’s throat.

Allosaurus, by contrast, is taking some down time.

And those dioramas from the old hall I was afraid I’d miss?  The new exhibit features a whole series of new ones, as exquisitely detailed as the masterpieces from the former exhibit.

Take this scene from the Cretaceous, for example.  If these little hadrosaurs know what’s good for them, they’ll put some serious distance between themselves and this creek bed…

…because somebody on the other side of it is about to wake up.

A much more recent scene, as a mastodon finds itself mired down at Big Bone Lick in Kentucky.

Yes, mammals are here, too—from the armored Glyptodon

…to the “Irish elk” Megaloceras.

And here’s everybody’s favorite sail-backed distant cousin, Dimetrodon.

Moving on from the terrestrial to the marine, here’s a mosasaur…

…and a mosasaur meal.

And we haven’t even gotten to the fish, invertebrates, or plants yet.  You could easily spend three or four hours wandering through the hall without taking it all in.

In fact, if there’s anything to criticize, it’s this: Deep Time perhaps tries to do too much from an interpretive standpoint.  The main theme is the extent to which changes in climate impacted environments and drove evolution, and how humans are accelerating these changes at a dangerous rate.  But the exhibit also delves into convergent evolution, migrations, predator-prey relationships, and taphonomy.

But having a lot to chew on is a great problem to have when you’re a museum visitor.  This is definitely an experience that will reward repeat visits.  And since I plan on repeating my visit annually, I’m totally okay with that.

GDP: An eruption of paleonews

Fossil resources under threat, a volcanic trailer, two new theropods, and a tweeting tyrannosaur.  It’s all in today’s Gratuitous Dinosaur Post.

Valley of the Gods in Bears Ears National Monument. By US Bureau of Land Management (http://mypubliclands.tumblr.com/) [Public domain], via Wikimedia Commons

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.

A peek at the awesomeness coming in 2017

Hey, here’s a pleasant surprise!  USA Today has an excerpt from Dragon Teeth, the Bone Wars novel coming out next May by the late, great Michael Crichton.  Looks like the main character is a young man from a well-to-do Philadelphia family who joins the first big Gilded Age fossil rush.

The dust jacket looks pretty cool, although it’s a little odd to see a Tyrannosaurus on the cover of a novel set in the 1870s.  Some material now recognized as belonging to T. rex did turn up in the late 1800s, some of it discovered by fossil hunters involved in the Cope-Marsh feud.  In fact, Cope himself published a description of a couple of vertebrae from South Dakota that have since been identified as T. rex remains.  But the name Tyrannosaurus rex didn’t appear in the scientific literature until about thirty years after Cope and Marsh started duking it out.  No big deal, though—and not the first time Tyrannosaurus has made a somewhat chronologically-inappropriate appearance on the front of a Crichton novel.  After all, most editions of Jurassic Park featured a T. rex on the cover, even though the Jurassic Period ended almost eighty million years before the tyrant lizard king showed up.

While we’re on the subject of prehistoric beasties and awesome stuff coming out in 2017, have you seen the Kong: Skull Island trailer yet?  I don’t know if I’ve mentioned this here before, but I’ve been a huge King Kong fan since I was about six.  (The fact that the ’33 film was chock full of dinosaurs might’ve had something to do with it.)   Maybe I should add a “Gratuitous Giant Ape Posts” category since I’m already subjecting you folks to periodic dino digressions.

The movie’s set in the Godzilla universe, and this ginormous, bipedal Kong seems to have more in common with the Toho version than the old school one that climbed the Empire State Building with a blonde in his hand.  Me, I prefer the original take on Kong, and I’m disappointed by the lack of dinosaurs in the trailer, but this is still my most anticipated movie of 2017.

Beast in the basement

Whenever I’m down in the McClung Museum’s basement, I stop to pay my respects to an old friend.

img_2073Old, that is, in a relative sense.  This is a cast facsimile of a T. rex skull rather than the real thing.  But this bad boy (girl?) and I go back a long way.  My dad used to indulge my dino obsession by taking me to the McClung Museum on weekends so I could hang out in the old geology and fossil exhibit, where the T. rex skull went on display sometime back in the early or mid-nineties.

That exhibit has now gone the way of the specimens it once showcased.  The McClung’s current geology and fossil gallery opened in 2002 with some new dino skull casts and gorgeous dioramas, but sans tyrant lizard king.  Now the T. rex is enjoying semi-retirement downstairs, although we wheel him out for school tours from time to time.

Those of you who are fellow paleo-nerds may recognize the skull as a copy of one of the most famous dinosaur specimens in the world: AMNH 5027, excavated by the great fossil hunter Barnum Brown in Montana back in 1908.  The original skull is on display in the American Museum of Natural History in New York…

…right in front of the skeleton it was once attached to.  Fossil T. rex skulls are so heavy that it’s hard to mount them at standing height, so most museum specimens have lighter copies stuck on the ends of their necks.

AMNH 5027 wasn’t the first T. rex specimen to be described.  But it was the first to be found with an intact cranium, making it a popular choice for replication.  (Check out the wonderful Extinct Monsters blog for the history of T. rex on display and the proliferation of 5027 clones in museums all over the world.)  If you’re at a museum that has a tyrannosaur cast, one easy way to tell if it’s a copy of 5027 is to look at it head-on.  The original looks a bit smashed on the upper left side, as if it’s starting to collapse inward like a rotting pumpkin.  You can see the distortion in this photo of UC-Berkely’s replica:

One other thing to take note of when you’re looking head-on at a T. rex is the position of the eye sockets.  Although they’re on the sides of the head, they’re oriented so that the eyes themselves would have faced forward, which probably meant good depth perception.  In fact, research by Kent Stevens indicates that T. rex had superb vision.  Combine an eagle’s eyesight, an exceptional sense of smell, and a bone-crushing bite, wrap it all up in a forty-foot package, and you’ve got one of the most remarkable carnivores in the history of life on this planet.  In other words, it’s probably not a good idea to stand still and hope he doesn’t notice you.

Anyway, as awesome as this guy looked in the old exhibit, I’m sort of glad he’s taken up quarters behind the scenes.  As a kid, I used to stand in front of his display case and wonder what it would feel like to run my hands across those bony protrusions and along those fearsome jaws.  Now I don’t have to wonder, and it’s one of many reasons I love my job.
