Thalamosaurs

Thalamosaurs are a group of extinct reptiles that lived during the Late Triassic and Early Jurassic periods, approximately 231 to 175 million years ago. They are known for their distinctive skull structure, which features a large, rounded skull and a large, toothless beak. Thalamosaurs are believed to have been herbivorous, feeding on plants and other soft materials.

The name "Thalamosaurus" comes from the Greek words "thalamos," meaning "chamber," and "sauros," meaning "lizard." This name reflects the unique chamber-like structure of the skull, which is thought to have been used for storing and grinding food.

Thalamosaurs are known from fossils found in Europe, North America, and South America. They are one of the few groups of reptiles that survived the Permian-Triassic extinction event, which wiped out most other reptile groups. Thalamosaurs are thought to have been one of the first groups of reptiles to evolve a beak, which allowed them to feed on a wider range of plant materials.

Thalamosaurs are an important group of reptiles for understanding the evolution of reptiles and the recovery of life after the Permian-Triassic extinction event. Their unique skull structure and herbivorous diet make them a fascinating subject of study for paleontologists.
