History and prehistory in the City of Angels

If you find yourself visiting southern California and you’d like a good crash course in the area’s history, let me recommend a visit to the Natural History Museum of Los Angeles County. Most of us associate natural history museums with fossils and taxidermy, but the NHMLAC also has an exhibit called “Becoming Los Angeles,” which covers L.A.’s story from the arrival of the Spanish up to the present. It opened last year.

I’m not that familiar with the history of California, so this exhibit was an education for me. The section on the Spanish mission system is especially interesting; it explains the impact of European colonization on both the land and the people. The arrival of domestic cattle, for example, dramatically impacted southern California’s vegetation. Cows ate up the grasses that were native to the area while depositing foreign seeds in their dung. Hence the slogan emblazoned on souvenirs in the museum’s gift shop: Cow poop changed L.A.!

Becoming Los Angeles features some pretty neat artifacts. Here’s the table on which the Treaty of Cahuenga was signed in 1847, ending hostilities in the Mexican-American War in California. Of course, the war didn’t officially end until the Treaty of Guadalupe Hidalgo the following year.

The exhibit also covers more recent history, including the city’s role in WWII and the birth of the local aviation and entertainment industries. Here’s another historically significant piece of furniture: Walt Disney’s animation stand, used to make the first Mickey Mouse cartoons.

Other objects on display include Spanish crucifixes from the colonial era, Indian tools, and one of Charlie Chaplin’s costumes.

But hey…I didn’t go to L.A. to see history exhibits. I was off the clock. You guys know where this is headed, right?

If you like tyrannosaurs, you’re in luck. There are more T. rex mounts at the NHMLAC than you can shake a severed goat leg at. One of them is facing off against a Triceratops in the foyer.

More tyrannosaur skeletons are in the main dinosaur exhibit. This is a really cool mount, because it’s the only place in the world where you can see three T. rexes of different ages posed together in a growth series. At two years old, this is the youngest known T. rex specimen.

The second tyrannosaur is a twenty-foot adolescent. T. rex grew remarkably fast in its early teens, packing on up to 1.5 tons per year.

And here’s the third animal, close to full size.

Mamenchisaurus, a long-necked sauropod from China, dominates the first dinosaur gallery.

Another Triceratops.

Carnotaurus, the bulldog-faced meat-eater from Argentina. On a related note, on my last night in town my friends took me to an Argentine restaurant. Best thing about L.A. is the variety of dining options.

A hadrosaur skull. The horny part of the “duckbill” is really visible on this specimen.

Allosaurus vs Stegosaurus. I do love a good Allosaurus skeleton. The Denver Museum of Natural History has a very similar mount.

An ornithomimid. I think it’s Struthiomimus, but I don’t remember exactly.

Unfortunately, we didn’t have time for the La Brea Tar Pits, but the NHMLAC does have quite a few specimens from the site, like this saber-toothed cat.

And while we’re on the subject of all things prehistoric, the grand finale of my L.A. trip was a pilgrimage to the original Jurassic Park ride at Universal Studious Hollywood.

IMG_0971

I was wearing a t-shirt from the Jurassic Park River Adventure at Universal Orlando, and some of the ride operators at the Hollywood version asked me which one was better. As a connoisseur of all things JP, I feel eminently qualified to address this question, so here goes.

In terms of the rides themselves, it’s pretty much a toss-up. The Hollywood version has a couple of neat outdoor effects that are absent in Orlando, an additional (albeit brief) encounter with the T. rex, and better-looking sauropods in the opening scene. On the other hand, I think the Florida ride seems a bit less rushed, which means much better pacing, a more coherent story, and a more effective build-up of suspense. For these reasons, I have a slight personal preference for Orlando’s version, but you can’t go wrong with either one.

Looking beyond the boat ride to the overall Jurassic Park experience, Orlando has one big advantage in that Universal had room to build an entire Isla Nublar there, complete with a replica of the visitor center, more dino-themed dining and shopping establishments, and some other attractions besides the main boat ride. But Hollywood still has plenty to offer. On the studio tram tour, you’ll see vehicles used in The Lost World and the water tank used to film the final Spinosaurus attack in JPIII. The die-hard fan should visit both parks—Hollywood because it’s steeped in the history of the franchise, Orlando because you can immerse yourself in the movie’s fictional universe. (Assuming, of course, you can ignore that darned Harry Potter castle looming above the treeline. Zoning laws, people. Zoning laws.)

And that’s a wrap. Back to business as usual.

They’ve figured out how to open doors

I will now drop everything to address a tragically common misconception

If only I had a nickel for every time I’ve heard this one.

This time it’s Cracked.com that’s accusing Steven Spielberg of making a steep drop appear out of nowhere during the T. rex attack.

There’s clearly nowhere for them to go. If they stay on the road, they’ll be eaten. If they run into the jungle, they’ll probably catch some kind of awful tropical parasite. And then be eaten.

Cut To …

Oh, wait, no: They can climb down this sheer cliff face, which just appeared out of absolutely nowhere.

And we say “appeared” because it literally appeared there during the edit between those two scenes. The tyrannosaur breaks through the fence, then the heroes crawl through the broken fence the dinosaur just burst through, only to find the concrete wall….

Oh, you think the greatest scene ever committed to film has a glaring mistake, do you? Well, I’ve got some news for you.

If you’re standing in the spot where the kids’ car is stopped and facing the fence, the goat tether would be directly in front of you, and that steep drop would be slightly to the left, along the edge of the paddock that’s perpendicular to the road.  After the T. rex overturns the car, she nudges it to the left, past the spot where the goat was tethered, and then pushes it into the drop.  Okay?

There.  I’ve done my good deed for the day.

And don’t get me started on people who can’t figure out how the T. rex got into the Visitor Center when there’s obviously a ginormous opening in the wall.

World War II’s oldest casualties

With The Monuments Men hitting theaters this week, I thought this might be a good opportunity to discuss the fate of valuable artifacts during WWII.  And this leads us—as all things inevitably must—to the subject of extinct reptiles.

About a hundred million years ago, North Africa was the world capital of big, carnivorous dinosaurs.  The biggest of them all was Spinosaurus, top contender for the largest known meat-eating dinosaur of all time.  Even the lowest estimates of its size would make this animal longer than T. rex, and the higher estimates—up to 59 feet from nose to tail tip—are longer by far than those for any other theropod dinosaur known to science.

Spinosaurus got its moniker from the row of spines atop its vertebrae, some of them over five feet high, giving it a prominent sail or ridge running the length of its back.  The German paleontologist Ernst Stromer came up with the name in 1915, based on some jawbones, vertebrae, and ribs discovered three years earlier in Egypt.

Ernst Stromer

For thirty years, these fossils were safe and sound in Munich’s Paläontologisches Museum.  Then the war came, and European museums weren’t safe havens anymore.

On the night of April 24, 1944 the Royal Air Force hit Munich with a bombing raid that wrecked the museum and destroyed the Spinosaurus fossils inside.  Spinosaurus bones aren’t that plentiful, so the loss of any of them is a big deal, but the loss of this specimen was especially significant because it was the holotype (the individual used in the first official scientific description of the species).  All that remains of it today are Stromer’s notes, drawings, and photos.

Perhaps the rarity and fragmentary nature of Spinosaurus fossils help explain why this dinosaur hasn’t always been as popular as you’d expect.  It’s more well known now than it used to be, largely thanks to a starring role as the main antagonist in Jurassic Park III.

I’m partial to T. rex myself, but that scene is just freaking awesome.

Another massive carnivorous dino prowling around Cretaceous North Africa was Carcharodontosaurus, first discovered in the 192os and re-named by Stromer in 1931.  Like Spinosaurus, this guy was huge—upwards of forty feet long.  Its five-foot skull was lined with serrated, eight-inch teeth.

And also like Spinosaurus, the holotype got pulverized by Allied bombs falling on Munich.  Expeditions to the Sahara unearthed additional specimens in the 1990s, but Stromer’s original went up in smoke during the war.

In fact, the RAF’s April attack on Munich basically wiped out Stromer’s remarkable collection, including the type specimen of the carnivorous dinosaur Bahariasaurus, the only known specimen of the unusual prehistoric crocodile Stomatosuchus, and the bones of the long-necked dinosaur Aegyptosaurus.  And the war cost Stromer much more than his fossils.  Two of his sons died in the army, while the third spent years as a prisoner of the Russians.

Incidentally, the First World War took its toll on paleontology, too.  In December 1916 the German raider Möwe sank the Canadian ship Mount Temple, along with the twenty-two crates of hadrosaur and turtle fossils on board.

Fort Sanders sesquicentennial for Black Friday

In 1863 Nov. 29 fell on a Sunday instead of a Friday, but it was a pretty black day nonetheless, at least for the hapless Rebel soldiers who launched a disastrous assault against Fort Sanders at Knoxville.  Those twenty bloody minutes ended Longstreet’s effort to re-take the city for the Confederacy, following its occupation by Burnside that September.

The attack on Ft. Sanders was neither a particularly big battle as far as Civil War engagements went nor as consequential as what was going on down in Chattanooga.  But it’s a pretty big deal for history buffs here in my neck of the woods, so here’s another anniversary link-fest for you.

  • Knoxville’s own historical columnist Jack Neely on the assault
  • The Knoxville News-Sentinel‘s sesquicentennial coverage of the war in East Tennessee
  • If you haven’t seen the McClung Museum’s exhibit on Ft. Sanders, you should definitely check it out.  They have fossils, too!  (By the way, that new Edmontosaurus is now called “Monty.”)
  • The East Tennessee Historical Society has some nifty Civil War displays of their own, and they’re commemorating the Ft. Sanders anniversary with a free admission day.
  •  Need to read up on the contest for control of Knoxville?  I recommend The Knoxville Campaign by Earl Hess, Lincolnites and Rebels by Robert Tracy McKenzie, and Divided Loyalties by Digby Gordon Seymour.  For additional background, try Noel Fisher’s War at Every Door and W. Todd Groce’s Mountain Rebels.
  • Last year we paid a virtual visit to the site of the battle.  The fort is long gone, but there are still a few landmarks from the Knoxville Campaign around.  Click here to book a guided tour, or stop by Longstreet’s headquarters and the Mabry-Hazen House.
  • Watch the battle reenacted at a replicated Ft. Sanders, constructed for a documentary produced in conjunction with the McClung Museum’s exhibit.
  • And finally, here’s a depiction of the attack by Lloyd Branson, the same Tennessee artist who did the painting of the Sycamore Shoals muster at the top of this blog:

UT has a dinosaur now

Of course, I heartily approve of this.

A 2,400-pound, 24-foot-long bronze skeleton of an Edmontosaurus annectens—a hadrosaur, or duck-billed dinosaur—was installed today outside the front entrance of the McClung Museum of Natural History and Culture as part of the museum’s fiftieth anniversary celebration.

Its selection is fitting because the Edmontosaurus is a hadrosaur, and these types of dinosaurs once roamed the coastal plains of Tennessee. The McClung Museum also houses actual hadrosaur bones—the only non-avian dinosaur bones ever found in the state—in its Geology and Fossil History of Tennessee permanent exhibit.

They’re holding a contest to name this sucker at the McClung Museum website; November 8 is the deadline for submissions.

I think the name should relate to East Tennessee history: Chucky Jack if it’s a male, Bonnie Kate if it’s a female.  Too bad it’s so hard to tell the difference.

It’s a Jurassic World; you just live in it

We’ve got a title and a release date.  Jurassic World opens June 12, 2015.  Serious aficionados may recall that this was also the title given to the single-volume edition of the Crichton novels.
