 Tracks discovered by Matthew <unk> ( Morrison Natural History Museum , Colorado ) suggest that Stegosaurus lived in multiple @-@ age herds . One group of tracks is interpreted as showing four or five baby stegosaurs moving in the same direction , while another has a juvenile stegosaur track with an adult track overprinting it . Stegosaurus may have preferred drier settings than other common Morrison Formation dinosaurs , such as Allosaurus , Apatosaurus , Camarasaurus , and Diplodocus .
