Meet the Texas Dinosaurs and Their Friends

The Mesozoic Era is called "The Age of Reptiles" because that was the era (225-65 million years ago) when the dinosaurs lived and were the dominant life form. The Mesozoic is divided into 3 periods, the Triassic, Jurassic and the Cretaceous. The Cretaceous Period was the most productive of the Mesozoic in deposition of fossils found in Texas. Each period featured different dinosaurs that lived during that time. Dinosaurs are a special group of reptiles that lived on land. They did not fly or swim.
