Different dinosaurs Deinonychus can have lived along within the Early Cretaceous Length of what’s now North The us come with:
- Tenontosaurus: A big herbivorous dinosaur that used to be most likely one of the crucial number one prey species for Deinonychus. Fossil proof displays that Tenontosaurus bones incessantly endure the marks of Deinonychus enamel and claws.
- Sauropelta: An armored dinosaur identified for its frame coated with bony plates and spikes, offering coverage in opposition to predators like Deinonychus.
- Microvenator: A smaller theropod dinosaur that may have competed with Deinonychus for meals or occupied other ecological niches.
- Acrocanthosaurus: A miles greater theropod, which used to be a best predator in the similar areas, doubtlessly resulting in occasional festival with Deinonychus.
Specimens of Deinonychus and the entire above dinosaurs had been present in rocks of the Cloverly Formation, which lies within the western United States.
Along with dinosaurs, Deinonychus would have shared its atmosphere with more than a few different animals, together with early mammals, lizards, turtles, and crocodilians.
