The subject of blockbuster films, history museum exhibits and much more, dinosaurs continue to interest people today after first appearing approximately 230 million years ago. Their increasingly large size meant they could not continue to support themselves on two legs.ĭinosaurs in the ornithischian order first evolved their bird-like hip structure in the Late Triassic epoch, in smaller bipedal herbivores such as Pisanosaurus and Lesothosaurus.īy the Cretaceous period, descendents of these dinosaurs were more common than their lizard-hipped counterparts, and consisted of three key groups: marginocephalians, including large, horned dinosaurs such as Triceratops and domeskulled pachycephalosaurs ornithopods, including large and small bipedal herbivores such as Hypsilophodon and Iguanodon and thyreophorans, which boasted the full body-armoured giants such as Stegosaurus and Ankylosaurus.Dinosaurs types are many and varied, from small bird-like creatures to the largest animals ever to walk on Earth.

From the moment dinosaurs appeared on earth, the evolution of their different species has left the mark of a multitude of different genera and species on the planet. Types of dinosaurs and all their classifications.

For dinosaurs, it is a good an indicator of diversity as any, as most genera have only one representative.

The earliest members of this suborder to thrive were the prosauropods, but the biggest of all were the sauropods. How many types of dinosaurs were there By Ed Yong. Carnivores are a group that includes all the meat-eating dinosaurs. Sauropodomorphs were longnecked plant-eaters including Diplodocus and Argentinosaurus, the largest animals ever to walk the earth from the Late Triassic epoch onwards.
