Allosaurus amplus

Allosaurus amplus

†Allosaurus amplus was a species of †Allosaurus from the Late Jurassic (~155-150 Ma) Morrison Formation of the western USA. Known from fragmentary material, it was a large bipedal carnivore. The name 'amplus' refers to the large size of the fossils. Some researchers consider this a nomen dubium or synonym of A. fragilis due to the incomplete nature of the material.

Jurassic Late Mesozoic Era

Allosaurus amplus lived during the Jurassic Late period of the Mesozoic Era, approximately 161.5 to 145.0 million years ago.

One of the most iconic periods for dinosaurs. Giant sauropods like Brachiosaurus and Diplodocus roamed alongside predators like Allosaurus. Archaeopteryx, the earliest known bird, appeared. The Morrison Formation preserves an extraordinary fossil record from this time.
