Crystal Palace Field Trip Part 1: Walking With Victorian Monsters
The Crystal Palace Dinosaurs take their name from the original Crystal Palace, a glass-paned exhibition building originally constructed for a World's Fair in Hyde Park in 1851.
In 1854 the structure was relocated 14km (~9 miles) south to the newly-created Crystal Palace Park, and a collection of over 30 life-sized statues of prehistoric animals were commissioned to accompany the reopening – creating a sort of Victorian dinosaur theme park – sculpted by Benjamin Waterhouse Hawkins with consultation from paleontologist Sir Richard Owen.
The Palace building itself burned down completely in 1936, and today only the ruins of its terraces remain in the northeast of the park grounds.

Six sphinx statues based on the Great Sphinx of Tanis also survive up among the Palace ruins, flanking some of the terrace staircases. They fell into serious disrepair during the latter half of the 20th century, but in 2017 they all finally got some much-needed preservation work, repairing them and restoring their original Victorian red paint jobs.

…But let's get to what we're really here for. Dinosaurs! (…And assorted other prehistoric beasties!)
The "Dinosaur Court" down in the south end of the park still remains to this day, displayed across several islands in a man-made lake. Over the decades they've been through multiple cycles of neglect and renovation, and are currently cared for by the London Borough of Bromley (Crystal Palace Park Trust are due to take over custodial duties in September 2023), with promotion and fundraising assistance from organizations like Historic England and the Friends of the Crystal Palace Dinosaurs charity.
Just about 170 years old now, the Crystal Palace Dinosaurs represent fifteen different types of fossil creatures known to 1850s Victorian science, with only three actual dinosaur species featured. Although often derided for being outdated and very inaccurate by modern standards, they were actually incredibly good efforts at the time, especially taking into account that the field of paleontology was still in its very early days.
They also just have a lot of charm, with toothy grins and surprisingly dynamic poses.
Unfortunately on the day I visited in early August 2023 most of the statues were heavily obscured by plant growth, both on their islands and on the sides of the paths they can usually be viewed from. Since I'd seen images from about a month ago showing things being less overgrown, this was probably just some unlucky timing on my part coinciding with some explosive summer foliage growth.
The first island on the trail features a few Permian and Triassic animals which were only known from fragmentary remains in the 1850s. These "labyrinthodonts" were recognized as having similarities to both amphibians and reptiles, and so were depicted with boxy toothy jaws, warty skin, stumpy tails, and long frog-like back legs.
Today we'd call these particular animals temnospondyl amphibians, specifically Mastodonsaurus, and we know they were actually shaped more like giant salamanders with longer flatter crocodilian-like jaws, smaller legs, and long paddle-like tails.

Somewhere in the foliage beyond this specific "labyrinthodont" there was also supposed to be a pair of dicynodonts, but I couldn't see much of them at all and didn't manage to get a remotely visible photograph.

These Dicynodon are depicted as looking like sabre-toothed turtles complete with shells. That was fairly speculative even for the time, but considering only their weird turtle-beaked-and-walrus-tusked skulls were known it was probably the best guess Hawkins and Owen had. Today we know these animals were actually synapsids related to modern mammals, but Victorian understanding considered them to be a type of reptile.
Modern reconstructions of dicynodonts have a slightly different face shape, along with squat pig-like bodies and semi-sprawling limbs. They may have had fur, but currently the only known actual skin impressions from the genus Lystrosaurus show leathery bumpy hairless skin.

Next time: the Jurassic and Cretaceous sculptures!
Referred Species: M. jaegeri, M. cappalensis, M. giganteus, M. torvus
Status: Extinct
Time and Place: 247 to 237 million years ago, from the Anisian to the Ladinian of the Middle Triassic
Mastodonsaurus is known mostly from Germany and Russia.
Physical Description: Mastodonsaurus was a very large temnospondyl, growing up to 6 meters (20 feet) long. It’s one of the largest “amphibians” (if you accept the term to mean non-amniote tetrapods) known from actually decent remains. This thing’s downright badass. Its head was large, wide and flattened, with the eyes positioned at the top about ⅔ of the way back. The head was roughly-textured, being covered in rugosities that suggest a tight covering of skin. The upper and lower jaws were filled with spikelike teeth, of which there were two rows in the upper jaw. Each tooth has a complex labyrinthine structure in cross section, leading to the colloquialism “labyrinthodont” for big temnospondyls like this. Two teeth in the front of the lower jaw had developed into large tusks, which were so large that there are holes on the top of the jaw for the tusks to go through when the mouth was closed. I repeat: IT HAD HOLES IN ITS SKULL BECAUSE ITS TEETH WERE SO BIG. That’s downright gnarly. The upper jaw also had enlarged fanglike teeth on the palate, but they weren’t that huge. Postcranially Mastodonsaurus was similar to other temnospondyls, with short, sprawling limbs and a powerful tail.
Diet: Mastodonsaurus’s diet likely consisted of any living or until-recently-living animal that happened to be in the water (including if it was pulled in).
Behavior: Mastodonsaurus likely lived similarly to modern crocodiles, lurking in waterways waiting for prey. In the water it may have done short chases after prey such as fish and other temnospondyls, but it probably ambushed tetrapod prey. Its limbs were quite small relative to the rest of its body, indicating that it likely spent most of, or even almost all of, its time in the water. It may have been able to attack animals on the banks of waterways, but that’s probably the most it did on a regular basis: grabbing prey on the shore of the water and dragging it back in to be eaten.
Ecosystem: Mastodonsaurus lived in environments with lots of freshwater. Some Mastodonsaurus-preserving environments also bear marine fossils, suggesting it may have also lived in coastal deltas or estuaries. M. jaegeri, M. cappalensis and M. giganteus lived in what is now west-central Europe. This area was evidently very wet, as evidenced by the variety of aquatic animals discovered there. These include fellow temnospondyl Gerrothorax, the nothosaurs Nothosaurus and Simosaurus, the early turtle Pappochelys, Tanystropheus, sharks, mollusks, and our old friends Ceratodus and Saurichthys. Some terrestrial animals also lived in this area, like cynodonts and the pseudosuchians Batrachotomus and Ctenosauriscus. Meanwhile, M. torvus lived in what is now Russia, alongside fellow temnospondyls Plagioscutum and Plagiorotus, the prolacertid Malutinisuchus, the rauisuchid Energosuchus, the erythrosuchid Chalishevia, and Elephantosaurus, a dicynodont with a horrible name.
Other: I try not to be an awesomebro, but this thing was pretty cool.

After the Permian extinction, Shellder lost the ability to evolve into Coiyler on its own, but it was able to take on a similar form through symbiosis with another pokemon. Slowpoke wouldn’t exist for another 200 million years, so Shellder bit the tails of Protopoli instead, causing it to evolve.
The maze pattern on this pokemon’s belly is different on every individual specimen.
