Dinosaurs

Dinosaurs are a diverse group of animals of the clade Dinosauria. They first appeared during the Triassic Period, approximately 230 million years ago, and were the dominant terrestrial vertebrates for 135 million years, from the beginning of the Jurassic (about 201 million years ago) until the end of the Cretaceous (66 million years ago), when the Cretaceous–Paleogene (K-T) event led to the extinction of most dinosaur groups at the close of the Mesozoic Era.
The fossil record indicates that modern birds evolved from theropod dinosaurs during the Jurassic Period and, consequently, they are considered a subgroup of dinosaurs by many paleontologists. Some birds survived the extinction event that occurred 66 million years ago, and their descendants continue the dinosaur lineage to the present day.
Dinosaurs appear prominently in The Lost World. However, eldritch creatures that mimic the shape and behaviors of dinosaurs and pterosaurs appear in both the novel Apocalypse and the web comic Reawakening, where they are the primary antagonists of the series.
