Is there a dinosaur called brontosaurus?
Brontosaurus was a large sauropod, a group of typically large dinosaurs with long necks and long tails. It lived during the Late Jurassic Period, from about 156 to 145 million years ago. The first recorded evidence of Brontosaurus was discovered in the 1870s in the USA.
Now scientists say that may have been the wrong call. Brontosaurus, as imagined by paleontologists in the late 1800s: aquatic, and wearing a Camarasaurus skull. ... The giant sauropod, long thought to be an Apatosaurus that someone got wrong, was actually its own type of dinosaur all along, scientists say Tuesday in PeerJ.
Brontosaurus had a long, thin neck and a small head adapted for a herbivorous lifestyle, a bulky, heavy torso, and a long, whip-like tail. The various species lived during the Late Jurassic epoch, in the Morrison Formation of what is now North America, and were extinct by the end of the Jurassic.
English Language Learners Definition of brontosaurus
: a very large dinosaur that had a long neck and tail.
Arguably the tallest dinosaur is Sauroposeidon proteles, a massive plant-eater discovered in North America. Thanks to a ludicrously long neck, it stood 17m (55 ft) tall, but relatively few fossils of it have been found.
Brachiosaurus - Mystery Dino
Other scientists believe the large nostrils on top of its head helped it to breathe better when swimming.
No. Brachiosaurus was a dinosaur that lived around 150 million years ago. By the time that Brachiosaurus became extinct, there were already early mammals called Eutheria living alongside the dinosaurs. The Eutheria gave rise to the placental mammals and then the Artiodactyla and, eventually, the modern giraffe.
Basic Dinosaur Facts
Dinosaur fossils have been found on all seven continents. All non-avian dinosaurs went extinct about 66 million years ago. There are roughly 700 known species of extinct dinosaurs. Modern birds are a kind of dinosaur because they share a common ancestor with non-avian dinosaurs.
The scientists conclude that three known species of Brontosaurus exist: Brontosaurus excelsus, the first discovered, as well as B. parvus and B. yahnahpin. Tschopp and his colleagues Octávio Mateus and Roger Benson detailed their findings online April 7 in PeerJ.
Nigersaurus, you might remember, we named for bones collected on the last expedition here three years ago. This sauropod (long-necked dinosaur) has an unusual skull containing as many as 500 slender teeth.
In 2015, it was renamed as the separate genus Galeamopus, and several other Diplodocus specimens were referred to that genus, leaving no definite Diplodocus skulls known. The two Morrison Formation sauropod genera Diplodocus and Barosaurus had very similar limb bones.
Brontosaurus was herbivorous and lived on land. Its long neck may have evolved to reach marshy vegetation some distance away or to reach leaves higher up in trees.
