The Archosaur is the 1st Dinosaur obtained in the Mesozoic Valley, which can generate Fossil 
. This one resembles a Prestosuchus, an archosaur from the Triassic Period.
Archosaurs are a group of diapsid amniotes and are broadly classified as reptiles. The living representatives of this group consist of birds and crocodilians. This group also includes all extinct dinosaurs, pterosaurs, and extinct relatives of crocodilians. Archosauria, the archosaur clade, is a crown group that includes the most recent common ancestor of living birds and crocodilians and all of its descendants. It includes two main clades: Pseudosuchia, which includes crocodilians and their extinct relatives, and Avemetatarsalia, which includes birds and their extinct relatives (such as non-avian dinosaurs and pterosaurs).

Tell Me the Tooth | One of the most important evolutionary advancements in the Archosaur family was the developement of teeth set in sockets. This made their teeth much sturdier and less likely to loosen or fall out while eating or in a fight. | 75 Archosaur |

A Tree Falls in a Forest | Birds and crocodilians are the only surviving members of the Archosaurs. Scientists believe that deforestation may have meant that ground-dwelling theropods survived the Cretaceous-Paleogene extinction event while larger species died out. | 200 Archosaur |
