Apatosaurus (/ əˌpætəˈsɔːrəs /; [3][4] meaning "deceptive lizard") is a genus of herbivorous sauropod dinosaur that lived in North America during the Late Jurassic period. Othniel Charles Marsh described and named the first-known species, A. ajax, in 1877, and a second species, A. louisae, was discovered and named by William H. Holland ...
Apatosaurinae (the name deriving from the type genus Apatosaurus, meaning "deceptive lizard") is a subfamily of diplodocid sauropods, an extinct group of large, quadrupedal dinosaurs, the other subfamily in Diplodocidae being Diplodocinae. Apatosaurines are distinguished by their more robust, stocky builds and shorter necks proportionally to ...
Brontosaurus. Brontosaurus (/ ˌbrɒntəˈsɔːrəs /; [1][2] meaning "thunder lizard" from the Greek words βροντή, brontē "thunder" and σαῦρος, sauros "lizard") is a genus of herbivorous sauropod dinosaur that lived in present-day United States during the Late Jurassic period. It was described by American paleontologist Othniel ...
Two dinos' bones were found within a few years, but in 1903, scientists decided the two were basically the same, and Apatosaurus won out. Now, paleontologists are advocating for a Brontosaurus ...
The Morrison Formation records an environment and time dominated by gigantic sauropod dinosaurs, such as Apatosaurus, Barosaurus, Brachiosaurus, Brontosaurus, and Camarasaurus. [8] Its great size may have been a deterrent to the predators Allosaurus and Ceratosaurus : their remains have been found in the same strata , which suggests that they ...
Diplodocoidea is a superfamily of sauropod dinosaurs, which included some of the longest animals of all time, including slender giants like Supersaurus, Diplodocus, Apatosaurus, and Amphicoelias. Most had very long necks and long, whip-like tails; however, one family (the dicraeosaurids) are the only known sauropods to have re-evolved a short ...
Earl Douglass (October 28, 1862 – January 13, 1931) was an American paleontologist who discovered the dinosaur Apatosaurus, playing a central role in one of the most important fossil finds in North America. [ 1][ 2][ 3] By 1922 Earl had unearthed and shipped more than 700,000 pounds of material including nearly 20 complete skeletons of ...
However, a subsequent analysis by Whitlock in 2011 showed that Supersaurus is slightly closer to Diplodocus than to Apatosaurus, and that Suuwassea is actually a primitive dicraeosaurid.
