<dinofyi-dinosaur slug="deinonychus"></dinofyi-dinosaur>Deinonychus revolutionized our understanding of dinosaurs when described by John Ostrom in 1969, sparking the Dinosaur Renaissance. Its large sickle-shaped toe claw and evidence of pack hunting suggested dinosaurs were active, intelligent animals.

Diet & Feeding
Deinonychus 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
Deinonychus 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.
