Allosaurus lucasi

†Allosaurus lucasi was a species of †Allosaurus from the Late Jurassic Morrison Formation of New Mexico, USA. Based on material from the Macho Creek area, it has been considered either a valid species or a synonym of †A. fragilis depending on the analysis. Named by Maddox in 1936, its taxonomic status remains under discussion as the systematics of †Allosaurus continue to be refined.

Diet & Feeding

Carnivore

Allosaurus lucasi was a meat-eating predator. Carnivorous dinosaurs were active hunters or scavengers, equipped with sharp teeth and claws for catching and consuming prey. They occupied the top of the food chain in their ecosystems.

Time Period

Jurassic Late Mesozoic Era

Allosaurus lucasi 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.
