Theropods Division Theropods Categories
Theropods are a group of bipedal saurischian dinosaurs. Although they were primarily carnivorous, a number of theropod families evolved herbivory during the Cretaceous Period. Theropods first appear during the Carnian age of the Late Triassic about 220 MYA and were the sole large terrestrial carnivores from the Early Jurassic until the close of the Cretaceous, about 65 MYA. Today, they are represented by the 9,300 living species of birds, which evolved in the Late Jurassic from small specialized coelurosaurian dinosaurs. |
