champsosaurus

The second largest reptile is the champsosaur Champsosaurus gigas.

Borealosuchus would have dominated the beach zone, while Champsosaurus is interpreted as a piscivore that swam near the bottom.

Champsosaurus (at least 3 species)

Dr. Erickson is the "proud parent" of several new-to-science reptiles, including the snorkler Champsosaurus gigas.

Champsosaurus resembled a gharial and, like gharials, hunted in rivers and swamps, catching fish with its long, tooth-lined jaws.

The named clade Neochoristodera includes Champsosaurus, Tchoiria, Simoedosaurus, Ikechosaurus and possibly Pachystropheus.

The Judith River Group preserves the remains of many aquatic amphibians and reptiles, including frogs, salamanders, turtles, Champsosaurus and crocodilians.

Thus far, no one has successfully challenged C. gigas as a new species, or another, even more evolved, predator that Dr. Erickson found near Wannagan and named Champsosaurus tenuis.

The saltwater plesiosaur Leurospondylus has been found in marine sediments in the Horseshoe Canyon, while freshwater environments were populated by turtles, Champsosaurus, and crocodilians like Leidyosuchus and Stangerochampsa.

Judiceratops shared its paleoenvironment with bony fishes, amphibians, the Choristoderan Champsosaurus, the hadrosaur Brachylophosaurus canadensis, theropods Dromaeosaurus, Gorgosaurus and Troodon, and with fellow ceratopsians Albertaceratops, Medusaceratops and Avaceratops.

I reported this sighting to Nebogipfel, who-retrieving a little more of that encyclopedic body of data stored in his little skull- identified it as Champsosaurus: an ancient creature, related to the crocodile, and in fact a survivor of the Age of the Dinosaurs-an Age already long vanished by this Palaeocene period.
