About

Ammosaurus major is one of the first non-sauropod sauropodomorphs known from North America and one of the few to survive into the Middle Jurassic, but it was initially assigned by O.C. Marsh to his Anchisaurus as Anchisaurus major when its partial rear-end was discovered in the Connecticut sandstone quarry of Charles O. Wolcott in 1889. Unfortunately the rest of it was in bits in South Manchester, stuck in a bridge that was built with blocks cut from the same quarry sometime earlier.

Nevertheless, Marsh pin-pointed enough differences in what he had available to separate his new specimen from the name-bearing Anchisaurus polyzelus from Springfield Armory at Massachusetts in 1891, and enough similarities in two more specimens from Walcott’s quarry to raise Anchisaurus solus and Anchisaurus colurus the same year.

Size

Ammosaurus Dinosaur measured over< 4.3 m (14 ft) long and stood about 1.8 m (6 ft) tall, though it would only be knee high if it was on all fours. At its largest, it would grow to the size of a small car.

Information

Ammosaurus Dinosaur (“lizard of the sand”) has been recognized by four incomplete skeletons found in United States and Canada regions. The first Ammosaurus skeleton was established in the late 1880s by a group of construction workers in the Connecticut Valley in the US, who were constructing, a bridge at the time. The valley was once a swamp, on which Ammosaurus would often search for food along its banks. Other fragmental skeletons have been found in Arizona and Nova Scotia.

Lived

Dinosaur was a herbivore/omnivore. It lived in the Jurassic period and inhabited North America. Its fossils have been found in places such as Nova Scotia (Canada).
