Extinct animals are those species which are no longer living. This group includes prehistoric animals like dinosaurs and ice-age mammals, as well as moden species like the Dodo.
Massospondylus was a medium-size prosauropod that lived in what is now modern-day North America and Africa. Its proportions suggest that it probably was able to stand up on its hind legs. What else is known about this dinosaur?
Mussaurus was a sauropod of modest proportions. This animal is important in that it may help explain the relationship between prosauropods and sauropods. It is thought that the Mussaurus serves as a sort of missing link between the two.
Riojasaurus was a quadrupedal dinosaur that could not rear up on its hind legs like some of its relatives. It was a large dinosaur that measured about 33 feet in length. What are some of the other dinosaurs the Riojasaurus is related to?
Scelidosaurus was discovered in the 19th century. At the time, it was one of the most complete dinosaur skeletons ever found. It was a heavily built plant eating dinosaur that grew to around 13 feet in length.
Scutellosaurus was a very unusual dinosaur because it was a two-legged dinosaur that had armor. Most armored dinosaurs walked on all fours. Many scientists believe this dinosaur to be the ancestor of later larger armored dinosaurs.
Sellosaurus was a sauropod of modest proportions. It was around 10 feet high and lived during the late Triassic Period. The sellosaurus lived in what is now modern day Germany. What else do we know about this dinosaur?
Syntarus was a small predator that was very fast and agile. Its jaws contained many small, bladelike teeth that were used for slicing the flesh of its prey. The bones of this dinosaur date back to the Early Jurassic Period.
Yunnanosaurus was a long-necked, four-legged plant-eater that lived in the Early Jurassic Period. The animal was about 18-25 feet in length and lived in what is now China. What do we know about this dinosaur's behavior?
Stegoceras has been one of the more interesting dinosaurs, partly because of the tangle of names that have been attached to it and also because of explanations that have been attached to its domed skull.
Although it may be long extinct, this quirky bird continues to amaze scientist. The latest discovery? An awesome “musket ball” weapon located on the tip of its wing structure. Could our world once again include this big, old flightless pigeon?
