The Genus Antrodemus is a group of extinct dinosaurs that lived during the Late Jurassic period. This group includes several species that are similar in size and appearance, but with slightly different skeletal features. Some synonyms for the Genus Antrodemus include Allosaurus fragilis, Saurophaganax maximus, and Epanterias amplexus. While these dinosaurs are classified under different names, they are all believed to be closely related and share many common traits. The study of these synonyms helps scientists better understand the evolution of these prehistoric beasts and their place in the larger family tree of dinosaurs.
