The Ultimate Guide to Jurassic Period Dinosaurs The Iguanodon is an ornithopod that lived from the late Jurassic period through to the late Cretaceous period and dwelled within Asia, Europe and North America. The Iguanodon was first discovered in 1822 and named three years later by Gideon Matell; it is one of the first dinosaurs to have been named.he Allosaurus. The Allosaurus was a large theropod dinosaur that roamed the Earth during the late Jurassic period some 155 to 150 million years ago. Allosaurus is important because it was one of the first well-known theropod dinosaurs.

It occurred from 199.6 to 145.5 million years ago, following the Triassic Period and preceding the Cretaceous Period. During the Jurassic Period, the supercontinent Pangaea split apart.y the Mesozoic Era, living things had evolved the capability of living on the land rather than being confined to the oceans. By the beginning of the Jurassic, plant life had evolved from Bryophytes, the low-growing mosses and liverworts that lacked vascular tissue and were confined to swampy moist areas.
