What dinosaur lived with a stegosaurus?

Answer 1

Stegosaurus lived in what is now the USA between 155 and 150 million years ago, as well as Portugal.

In America, Stegosaurus would have lived alongside the carnivores Allosaurus, Epanterias, Saurophaganax, Ceratosaurus, Elaphrosaurus, Torvosaurus, and Ornitholestes, the sauropods Diplodocus, Apatosaurus, Camarasaurus, Barosaurus, Eobrontosaurus, and Brachiosaurus, the ornithopods Dryosaurus, Camptosaurus, Drinker, Othnielia, Othnielosaurus, Uteodon, the stegosaur Hesperosaurus, the ankylosaurs Mymooropelta and Gargoyleosaurus,

In Portugal, Stegosaurus probably lived alongside the carnivores Allosaurus, Ceratosaurus, and Lourinhanosaurus, the stegosaurids Miragaia and Dacentrurus, the ornithopod Draconyx, the ankylosaur Dracopelta, and the sauropods Lusotitan and Dinheirosaurus.

Answer 2

The closest relatives of Stegosaurus were other stegosaurs, such as Kentrosaurus. Next were the other members of Thyreophora, the ankylosaurs. The closest living relatives of the stegosaurs are birds, as they descended from dinosaurs.

Answer 3

Stegosaurus was closely related to Ankylosaurus.

Back in the Mesozoic Era, the Jurassic stegosaurs (plated, spiked dinosaurs) were first cousins of the Cretaceous ankylosaurs (armored dinosaurs), both of these families grouped under the larger classification of "thyreophorans" (Greek for "shield bearers). Like Stegosaurus, Ankylosaurus was a low-slung, four-footed plant-eater, and even less appetizing in the eyes of ravenous raptors.
