[51][52] He also noted that the census is an imperfect depiction of the area's ecology since various biases in collecting and preservation may have affected the results. And what was its diet like? The tooth marks were identified in the humerus, foot bones and metatarsals, and this was seen as evidence for opportunistic scavenging, rather than wounds caused by intraspecific combat. Retrieved on July 16, 2013 from, "Estimating cranial musculoskeletal constraints in theropod dinosaurs", "The better to eat you with? It, too, would be done defensively, as Triceratopses had no reason to hunt dinosaurs when they ate plant matter.

Rex brain study reveals a refined "nose", "Olfactory acuity in theropods: palaeobiological and evolutionary implications", "Could Tyrannosaurus rex have been a scavenger rather than a predator? Summary: Scientists are researching which plants giant dinosaurs could have lived off more than 100 million years ago.

Elephants eat 6% of their body weight every day. Another possibility is that the horns functioned primarily as display structures, perhaps for signaling relative maturity to other members of the group.

Paleontologists estimate that the body length of Triceratops approached 9 metres (30 feet). Horner, Goodwin and Myhrvold's study, according to , actually shows what most palaeontologists believe; that Tyrannosaurus was an opportunistic carnivore; an animal that both hunted and scavenged.

Well, a group of scientists investigated this question by growing trees under Mesozoic conditions and creating a sort of dino-digester. Growing leaves of varying sizes and patterns, oak trees can stand 70 feet tall. [32][33] In modern animals, binocular vision is found mainly in predators.
