Oviraptor was a small, feathered dinosaur that lived during the Late Cretaceous period, around 75 million years ago. It was primarily found in what is now Mongolia. Oviraptor was characterized by its beak-like mouth, long arms, and a crest on its head, which may have been used for display or communication. Originally thought to be an egg thief, further research revealed that Oviraptor likely cared for its own eggs. It was a member of the group known as theropods, which includes other dinosaurs like Tyrannosaurus rex and Velociraptor. Oviraptor's unique features suggest it was well-adapted to its environment.
