Apatosaurus is a genus of herbivorous sauropod dinosaur that lived in North America during the Late Jurassic period. It is one of the more basal genera, with only Amphicoelias and possibly a new, unnamed genus more primitive. It lived about 152 to 151 million years ago during the late Kimmeridgian to early Tithonian age.
About Apatosaurus in brief
Apatosaurus is a genus of herbivorous sauropod dinosaur that lived in North America during the Late Jurassic period. Apatosaurus was a large, long-necked, quadrupedal animal with a long, whip-like tail. It is one of the more basal genera, with only Amphicoelias and possibly a new, unnamed genus more primitive. It lived about 152 to 151 million years ago during the late Kimmeridgian to early Tithonian age, and are now known from fossils in the Morrison Formation of modern-day Colorado, Oklahoma, New Mexico, Wyoming, and Utah in the United States. The skull, long thought to be similar to Camarasaurus, is much more similar to that of Diplodocus. It was a generalized browser that likely held its head elevated. Like that of other diplodocids, its tail may have been used as a whip to create loud noises. The jaws are lined with spatulate teeth suited to an ivorous diet. The snout is squared, having a square shape and having a maximum length of 11–30% greater than average and a mass of 32. 7–72. 6 t. The skull is small in relation to the largest titanosaurs, potentially potentially rivaling the largest titanosaur. A few specimens indicate a maximumlength of 11-30% more than average. The cervical vertebrae are less elongated and more heavily constructed than those of DiPLodocus, and the bones of the leg are much stockier despite being longer.
The tail was held above the ground during normal locomotion. It had a single claw on each forelimb and three on each hindlimb. It would have lived alongside dinosaurs such as Allosaurus, Camar asaurus, Diplosaurus, and Stegosaurus. A 2015 study concluded that Brontosaurus was a valid genus of sauro pod distinct from Apatososaurus, but not all paleontologists agree with this division. The type specimen of A. louisae was measured to be 21. 8 m, by measuring the vertebral column. In 1936 this was measured at 21.8 m long. Most size estimates are based on specimen CM 3018, the type specimen. In 2003, a study found that the individual was 21–22. 8 long and had a mass of 16. 4–22 4 t. A study that estimated mass of volnoughtus, Apatosaurus, and Giraffatitan CM 3018 at 8–38.2 t, in similar models to Dreadnought, the creature’s mass has been put as 35 t t 0 0 0. Past estimates have put the creature’s mass as high as 35.0 t 0. Some specimens of A ajax represent individuals 11 30% greater than average, suggesting that the skull is twice that of a larger animal.
