The Middle and Late Jurassic Periods were a time in which the dinosaurs took over the world. Learn more about the Middle and Late Jurassic dinosaurs, including the Yangchuanosaurus, Megalosaurus, and Archaepteryx.
No dinosaur has been the subject of as much controversy as Stegosaurus, the armored dinosaur of the Late Jurassic. For more than a hundred years, this strange plant-eater has baffled paleontologists and captured the imagination of the public.
Apatosaurus is perhaps one of the most famous dinosaurs because of the size of the animal. A fully grown Apatosaurus could reach up to 70 feet in length. The size of this dinosaur is what earned it the nickname "thunder lizard."
Archaepteryx was a very unique dinosaur in that it resembled a bird. It is known from only six fossils, but those fossils may be the most famous bones in the world. The Archaepteryx is the dinosaur that resembles modern birds the most.
The Brachiosaurus is a unique dinosaur because of the placement of the nostril openings, which were slightly above the eyes. Its front legs were longer than the rear, which made it able to eat the leaves from high tree branches.
Camptosaurus was one of the smallest plant-eating dinosaurs of the Late Jurassic. It weighed no more than 1,000 pounds and stood just five feet tall at the hips. Its strong legs were designed to help it avoid any predators.
The Compsognathus was one of the smallest known dinosaurs, which is amazing considering that it was a meat-eating dinosaur. This animal was about the size of a turkey and lived mostly near water. What else do we know about this dinosaur?
Dacentrurus was an armored dinosaur that was related to the Stegosaurus. The most prominent feature on this dinosaur was the set of large spikes on the end of the tail. It also had plates of bones on its back just like the Stegosaurus.
Diplodocus was an incredibly large dinosaur. It is the longest dinosaur known from complete skeletons. A fully grown adult could reach a length of 90 feet. Skeletons of this massive dinosaur have been found in North America.
Dryosaurus is the most important member of the family Dryosauridae. This is a group of small plant-eating dinosaurs from the Late Jurassic and Early Cretaceous of North America, eastern Africa is and Europe.
Kentrosaurus stands out among its relative stegosaurs because this dinosaur had an extra set of spines that stuck out above its hips. It had short front legs and neck which means it could only eat low shrubs and plants.
Megalosaurus was the first dinosaur that was described as a reptile. This dinosaur is often described as being part of the "waste bucket" genus because so many bones from other dinosaurs have been mistaken for being that of the Megalosaurus!
Omeisaurus is considered the most common of the Late Jurassic Chinese sauropods. The most prominent characteristic of this dinosaur is the extremely long neck the was uncommon for most North American dinosaurs.
Supersaurus was a dinosaur that truly deserved its name. It measured about 100 feet in length and lived in North America. This dinosaur lived on a diet that consisted mostly of chutes and leaves from the tops of trees.
The slow-moving, peaceful life of Tuojiangosaurus was sometimes interrupted by battles with predators such as Yangchuanosaurus and Szechuanosaurus. It would also battle with another male Tuojiangosaurus for females.
