Dinosaurs » A-Z Dinosaurs List » Ammosaurus Dinosaur
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
Ammosaurus is found in the Natural History Museum. Othniel C. Marsh first recognized Ammosaurus's remains,
he confused them with those of another dinosaur, Anchisaurus.
It was not until 1891 that he renamed the fossils as that
of Ammosaurus. Ironically, some of the Anchisaurus leftovers
were thought to be remains of prehistoric humans. Although
no Ammosaurus skull has ever been found, enough fossils
was found to decide that it was more closely related to
Plateosaurus than Anchisaurus as previously thought.
Ammosaurus Dinosaur lived during the early Jurassic period,
around 180 million
years ago. It was a
herbivore and could walk on both four or
two feet, the latter undoubtably allowing
it to reach higher branches. It had large
claws on its hands to allow it to strip
bark from trees and saplings. Compared
to the relax of its body, Ammosaurus had
both a long tail & neck, suggesting
that it would have walked on four legs
for most of its life, only on foot on two
to defend itself or reach food. To defend
itself, it would stand on its hind legs,
slashing at its assailant with its large
thumb claws on its fore legs.
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.
