What is a group of dinosaurs called?

The group of dinosaurs you are referring to are known as theropods.

Theropods were a diverse group of bipedal dinosaurs that flourished during the Mesozoic Era, between around 230 and 65 million years ago. They were characterized by their long necks, sharp teeth, and a similar skeletal structure that included a three-toed foot and clawed hands.

Some of the most famous theropods include the Tyrannosaurus rex, Velociraptor, and Spinosaurus. These carnivorous dinosaurs had a wide range of sizes, from small and agile to large and fearsome predators.

Theropods were highly successful and occupied various ecological niches. They had a wide range of adaptations, such as different jaw structures, teeth arrangements, and limb proportions, that suited them for different hunting strategies. Some theropods were fast runners, others were more suited for ambush attacks, and a few even had adaptations for swimming or flying.

Birds are the only living descendants of the theropod lineage. Recent scientific evidence suggests that birds evolved from small, feathered theropod dinosaurs. This link between birds and dinosaurs has revolutionized our understanding of dinosaur physiology and behavior.

Overall, theropods were a fascinating group of dinosaurs with diverse characteristics and adaptations that allow scientists to learn more about the ancient world they once ruled.
