Fun Facts
- ✓Protorosaurus lived during the late Permian period, roughly 255 million years ago, predating the first true dinosaurs by at least 20 million years.
- ✓For over a century after its discovery, scientists classified Protorosaurus as an ancestor of modern lizards, but 20th-century research overturned that entirely, placing it instead in Archosauromorpha, the group that gave rise to crocodilians and dinosaurs.
- ✓Fossils of Protorosaurus have been found in both Germany and Great Britain, making it one of the few late Permian reptiles known from multiple sites in what is now western Europe.
- ✓Protorosaurus had a notably long neck for a Permian reptile, a feature that hinted at its distant evolutionary connection to the long-necked archosauromorphs that would appear millions of years later.
- ✓The genus name Protorosaurus was coined in the 19th century, and its fossils were among the first Permian reptiles ever described by scientists, giving it a special place in the history of paleontology.
