Silesaurus opolensis
By José Carlos Cortés on @quetzalcuetzpalin-art
Name: Silesaurus opolensis
Name Meaning: Silesia Reptile
First Described: 2003
Described By: Dzik
Classification: Avemetatarsalia, Ornithodira, Dinosauromorpha, Dinosauriformes, Silesauridae
Silesaurus is the original Silesaurid - having lent its name to the group - and it comes from the Keuper Claystone in Silesia, Poland, living about 230 million years ago, in the Carnian age of the Late Triassic. As such, it was a relatively early Silesaurid, and in a different location than others in the group. It was also very large compared to other Silesaurids, about 2.3 meters long and mostly quadrupedal, though able to walk on two legs when needed. It was an herbivore, with small conical teeth, and a small beak at the front of its mouth. It was also a very derived Silesaurid, further lending credence to the idea that Dinosauromorphs evolved much earlier than previously believed. It moved upright, and rapidly, and was probably covered in filamentous integument - making it similar, but still distinct from, early dinosaurs.
