The Forgotten Archosaurs

Originating approximately 250 million years ago, the Archosauria ("Ruling Reptiles") became one of the most diverse and successful clades of vertebrates on earth. However, many of the amazing creatures that are a part of that diversity are often overshadowed by the poster children of the archosaurs - the dinosaurs. This blog looks at those often forgotten archosaurs, focusing especially on the croc-line, but occasionally looking at the bird-line and even outside of crown-group Archosauria.

Postosuchus heads to PEFO

Toast-asuchus!

So, you've likely seen me post about my little Safari Ltd. Postosuchus toy. As I traveled out to Petrified Forest this summer, I took a series of photos of the little guy, searching for his home. Below are some of my favorites, complete with geologic context.

By the way, I would like to apologize for the lack of posts. Internet has been problematic.

On Rt 24, headed to Colorado Springs, CO. The road was built on the Paleogene Dawson Formation.

Postosuchus searches for home, but finds himself in the Ordovician Manitou Limestone at Cave of the Winds.

Still searching, Postosuchus ends up in the Paleoproterozoic Routt Granite of Royal Gorge.


Oops! Went too far and ended up in the Cretaceous Dakota Shale.

Getting closer, Postosuchus checks out Delicate Arch in the Jurassic Entrada Sandstone of Arches National Park, UT

He finally made it! See here in the Rainbow Forest Museum of Petrified Forest NP, situated in the Triassic Chinle Formation.
