However, Brachiosaurus never faced off with Tyrannosaurus, but Triceratops did. These two lived in the same ecosystem at the same time, and likely interacted with one another. a b c d e f g h i Weishampel, D.B.; Dodson, Peter; Osmólska, H. (2004). The Dinosauria (Seconded.).

In phylogenetic taxonomy, the genus Triceratops has been used as a reference point in the definition of Dinosauria. Dinosaurs have been designated as all descendants of the most recent common ancestor of Triceratops and modern birds. [48] Furthermore, Ornithischia has been defined as those dinosaurs more closely related to Triceratops than to modern birds. [49] Paleobiology [ edit ] A Triceratops mounted next to a Tyrannosaurus at the Los Angeles Natural History MuseumIn movies and television, Triceratops are typically portrayed as herding animals, much like American bison or Hippopotamus. In reality, there is no evidence to suggest, or to reject, this notion. Groups of fossils have been found, but it is unknown whether these were family groups or some other social group.

The forelimbs, which were shorter than the rear ones, each had three hooves; the rear limbs had four hooves each. A 2012 study in the journal Proceedings of the Royal Society B suggested that Triceratops had an upright posture like an elephant's, rather than a sprawling, elbows-out posture like a lizard's.However, some other paleontologists contest this single-genus idea. In a 2012 PLOS ONE article, for instance, researchers presented evidence of Torosaurus bones that are not fully fused, suggesting the specimen is still immature (and, therefore, not a fully mature Triceratops). They further suggested the frill holes of Nedoceratops are pathological (related to a disease or health issue).

Ferns, cycads, and palms, were likely plentiful in these habitats. Distribution of the Triceratops Dinosaurs roamed the earth for around 160 million years. Humans have lived for only 2.5 million. Isn't that crazy? These epic reptilian-like beasts inspired legendary characters like Godzilla and the much-loved Jurassic Park movie. Who knows what dinosaurs were really like? We can only imagine. Types of Dinosaur Games Because of this, only select areas can actually give fossil evidence of the creatures that lived there. We know that these dinosaurs lived in North America, as scientists have discovered specimens in Colorado, Montana, Wyoming, South Dakota, and a few provinces in Canada. Diet of the Triceratops

Their bodies were stout, and they walked on all four of their limbs. Including their tail, these dinosaurs measured approximately 26 ft. in length. Interesting Facts About the Triceratops

Sternberg, C. H. (1917). Hunting Dinosaurs in the Badlands of the Red Deer River, Alberta, Canada. San Diego, California. p.261. {{ cite book}}: CS1 maint: location missing publisher ( link) It is likely Triceratops' horns and frill were used in combat against other Triceratops, as well as for visual display (mating, communication and species recognition), according to a 2009 PLOS ONE study.

The large frill also may have helped to increase body area to regulate body temperature. [79] A similar theory has been proposed regarding the plates of Stegosaurus, [80] although this use alone would not account for the bizarre and extravagant variation seen in different members of Ceratopsidae, which would rather support the sexual display theory.
