A diverse section of the Morrison Formation found in Wyoming

[Halichoeres]

This new paper describes the Little Houston Quarry, part of the Upper Jurassic Morrison Formation, found in eastern Wyoming. It's more diverse than most parts of the Morrison, including the recently official Allosaurus jimmadseni, and other dinosaurs like Camarasaurus, Nanosaurus. It also includes some mammals (Amblotherium, Docodon), turtles, choristoderes, crocodiles, arthropods, molluscs, horsetails, green algae, the lungfish Ceratodus, some actinopterygian fishes, and fragments of frogs and salamanders. Really cool stuff for diorama makers or paleoartists.

Some pieces of lizards and stem-tuataras:
