Allosauroidea

Allosauroidea is a major clade of large tetanuran theropod dinosaurs including the families Allosauridae, Carcharodontosauridae, Megaraptoridae, and Neovenatoridae. Active from the Middle Jurassic through the end of the Cretaceous, allosauroids were the dominant large carnivores across both Laurasian and Gondwanan continents for much of the Mesozoic.

Carnivore

Allosauroidea 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

Cretaceous Early Mesozoic Era

Allosauroidea lived during the Cretaceous Early period of the Mesozoic Era, approximately 145.0 to 100.5 million years ago.

The Cretaceous saw continued dinosaur evolution with the rise of ornithopods and early ceratopsians. Flowering plants first appeared and began to transform terrestrial ecosystems. Spinosaurus and other large theropods lived during this time.
