Acrocanthosaurus

†Acrocanthosaurus is a large carcharodontosaurid theropod from the Early Cretaceous (~113 Ma) of North America. Reaching 11.5m and ~6,200kg, it was the apex predator of its ecosystem. Distinctive tall neural spines along its back supported a muscular ridge. Named by Stovall and Langston in 1950, its trackways reveal evidence of predator-prey interactions.

Diet & Feeding

Carnivore

Acrocanthosaurus 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

Acrocanthosaurus 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.
