👉 "Gryphosaurus" is a genus of dinosaurs that lived during the Late Cretaceous period, around 68 to 64 million years ago. These prehistoric animals are known for their large size and powerful jaws, which allowed them to easily capture prey like birds and other large reptiles. Gryphosaurus was also highly intelligent and had a high metabolism, which likely enabled them to survive in the harsher conditions of the desert environment during which they lived.
