       Named in reference to the more famous Triceratops,‭ ‬Eotriceratops was a large ceratopsian dinosaur of the late Cretaceous.‭ ‬At three meters long from the snout to the tip of the neck frill,‭ ‬the skull of Eotriceratops is also immense.‭ ‬The skull at the base of the left brow horn has bite marks which indicates that the left horn may once have been in the mouth of a predator like a tyrannosaur.
       Eotriceratops is just one of many ceratopsian dinosaurs from the Horseshoe Canyon Formation,‭ ‬with Anchiceratops,‭ ‬Arrhinoceratops and Pachyrhinosaurus also known.‭ ‬Other dinosaurs that Eotriceratops may have come into contact with include the armoured Edmontonia and Anodontosaurus,‭ ‬as well as the hadrosaurs Hypacrosaurus,‭ ‬Saurolophus and Edmontosaurus.‭ ‬Principal predatory threats to Eotriceratops probably came from large tyrannosaurs like Albertosaurus,‭ ‬though smaller predators like Atrociraptor and Richardoestesia may have been threats to hatchlings and smaller juveniles.
