Sables Du Lussant (Paperback)

High Quality Content by WIKIPEDIA articles! The Sables du Lussant is a Mesozoic geologic formation. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus. Dinosaurs ("terrible, powerful, or wondrous lizards") were the dominant terrestrial vertebrate animals for over 160 million years, from the late Triassic period (about 230 million years ago) until the end of the Cretaceous period (about 65 million years ago), when the Cretaceous-Tertiary extinction event caused the extinction of most dinosaur species. The fossil record indicates that birds evolved from theropod dinosaurs during the Jurassic period, and most paleontologists regard them as the only clade of dinosaurs to have survived until the present day.
