Triassic

Late

Coelophysis

The name Coelophysis means "hollow form" or "hollow process", so named because of its hollow limb bones.  More info>

Jurassic

Early

Dilophosaurus

Dilophosaurus measured around 20 feet long and may have weighed half a ton. The most distinctive characteristic of Dilophosaurus is the pair of rounded crests on its skull, possibly used for display.  More info>

Late

Brachiosaurus

Brachiosaurus had a proportionally long neck, small skull, and large overall size, all of which are typical for sauropods. However, the proportions of Brachiosaurus are unlike most sauropods. The forelimbs were longer than the hind limbs, which result in a steeply inclined trunk, making the overall body shape reminiscent of a modern giraffe. Also, while the tail is a typical long dinosaur tail, it was relatively short for a sauropod.  More info>

Apatosaurus

One of the largest land animals that ever existed, with an average length of 23 m (75 ft) and a mass of at least 23 metric tons (25 short tons). Until the 1970s, it was believed that sauropods like Apatosaurus were too massive to support their own weight on dry land, so it was theorized that they must have lived partly submerged in water, perhaps in swamps. Recent findings do not support this, and sauropods are thought to have been fully terrestrial animals. More info>

Cretaceous

Early

Acrocanthosaurus

Fossil remains are found mainly in the U.S. states of Oklahoma, Texas, and Arkansas, although teeth attributed to Acrocanthosaurus have been found as far east as Maryland.  As the name suggests (“high-spined lizard”), it is best known for the high neural spines on many of its vertebrae, which most likely supported a ridge of muscle over the animal's neck, back and hips.  More info>

Late

Tyrannousaurus

With a name meaning "tyrant lizard", from Greek tyrannos meaning "tyrant," and sauros meaning "lizard", it is easily understandable that the dinosaur described would be a fixture in popular culture.  Tyrannosaurus rex was one of the largest land carnivores of all time; the largest complete specimen measured 42 feet long, and was 13.1 ft tall at the hips.

Edmontonia

An armoured dinosaur named after the Edmonton Formation (now the Horseshoe Canyon Formation), the unit of rock it was found in. Edmontonia had small, ridged bony plates on its back and head and many sharp spikes along its back and tail. The spikes could have been useful for intimidating predators or rival males, protection, or for self-defense.  More info>

Edmontosaurus

Edmontosaurus was widely distributed across western North America. The distribution of Edmontosaurus fossils suggests that it preferred coasts and coastal plains. It was a herbivore that could move on both two legs and four.  More info>

Ornithomimus

Ornithomimus was a relatively small swift bipedal animal, equipped with a small toothless beaked head, which may indicate an omnivorous diet. The brains of ornithomimids were large for dinosaurs, but this may not necessarily be a sign of greater intelligence; some paleontologists think that the enlarged portions of the brain were dedicated to kinesthetic coordination. More info>

Carnotaurus

This dinosaur’s name means "meat-eating bull", referring to its distinct bull-like horns (Latin carno meaning flesh and taurus meaning bull) was a large predatory dinosaur. The most distinctive features of Carnotaurus are the two thick horns above the eyes, and the extremely reduced forelimbs with four basic digits. More info>

Parasaurolophus

Parasaurolophus was a hadrosaurid, part of a diverse family of Cretaceous dinosaurs known for their variety of head adornments.  A large bipedal/quadrupedal herbivore, this dinosaur ate plants with a sophisticated skull that permitted a grinding motion analogous to chewing.  This dinosaur’s teeth were continually replaced; they were packed into dental batteries containing hundreds of teeth, and only a relative handful of which were in use at any time.
