Stegosaurus was a large plant-eating dinosaur that lived during the late Jurassic Period about 1508 million to 1557 million years ago primarily in western North America.
Dinosaur with spines on back. Updated April 20 2017. Scientists have dubbed the new dinosaur Bajadasaurus an herbivore that lived 140 million years ago according to the scientific journal Nature which first revealed the findings. However his argument becomes less robust upon comparison with other allegedly sailbacked animals.
It was about 15 feet long weighed around 550 pounds and walked on all four legs. BEHAVIOR Kentrosaurus like other Stegosaurians may have been a herding animal. As dinosaurs go stegosaurs are relatively easy to describe.
Spinosaurus a genus of theropod dinosaurs belonging to the family Spinosauridae known from incomplete North African fossils that date to Cenomanian times roughly 100 to 94 million years ago. Its back legs were twice as long as its front legs. A herbivorous dinosaur that fended off predators with a row of spines running along its back and lived 140 million years ago has been found in Argentine Patagonia.
Although Dimetrodon pictures make this animal look like a dinosaur it was in fact a synapsid which is a type of reptile. One of the most interesting facts about Dimetrodon is that paleontologists believe that the enormous fin on the back of this animal was used to regulate temperature. These quadrupedal small-to-medium-sized small-brained herbivores were characterized by the double rows of plates and spikes along their backs and the sharp spikes on the ends of their tails.
Spinosaurus gives its name to the dinosaur family Spinosauridae which includes two subfamilies. It walked on four legs and had a tall curved skull with large teeth of different sizes set along the jaws. This new species of dinosaur named Bajadasaurus pronuspinax lived 140 million years ago.
A dinosaur skeleton found in Patagonia has astonishingly long and sharp spikes coming out of its spine. The quadrupedal Stegosaurus is one of the most easily identifiable dinosaur genera due to the distinctive double row of kite-shaped plates rising vertically along the rounded back and the two pairs of long spikes extending horizontally near the end of the tail. It was a large animal but small for a sauropod reaching 9 to 10 meters 30 to 33 feet in length.
Long body and possibly. It is a member of the family Sphenacodontidae. This probably allowed the dinosaur to stand up briefly on its hind legs to forage for high vegetation.
The most prominent feature of Dimetrodon is the large neural spine sail on its back formed by elongated spines extending from the vertebrae. The theropod had a crocodylian like elongated face large arms. Bailey was right in that the elongated neural spines of pelycosaurs do stand out as very different from the spines of allegedly sailbacked dinosaurs.
Elongated and dense tail. Its name is an. Most distinctively it sported two parallel rows of tall spines down its neck and back taller than in any other known sauropod.
Spinosaurus means thorn lizard or spine lizard. Spinosaurus or spined reptile was named for its sail-back feature created by tall vertebral spines. Both dinosaursa carnivore and herbivore respectivelyhad elongated neural spines sticking out of many.
WHEN KENTROSAURUS LIVED Kentrosaurus lived during the late Jurassic Period about 156 to 150 million years ago. The most well known anatomical feature of this animal is the elongated spines on its back. The name comes from Spinosauruss most distinctive feature.
True to its nameGreek for living fortressAnimantarx was an unusually spiky nodosaur a subfamily of the ankylosaurs or armored dinosaurs which lacked clubbed tails that lived in middle Cretaceous North America and seems to have been closely related to both Edmontonia and Pawpawsaurus. Amargasaurus was first described in 1991 and contains a single known species Amargasaurus cazaui. The discovery of the new species.
It was about the size. By far the most famous stegosaur and the one that has lent its name to this entire family is of course Stegosaurus but there are at least a dozen other closely related genera most of which are no. A herbivorous dinosaur that fended off predators with a row of spines running along its back and lived 140 million years ago has been found in Argentine Patagonia.
A large sail on its back which consisted of spines covered by a layer of skin. Scientists think that this bony sail helped spinosaurus to warm up faster than other dinosaurs allowing it to hunt when others could not. It had an enormous sail-fin on its back and had a long tail.
