The large bony frill and three horns serve to make Triceratops one of the best-known dinosaurs, and this makes it a popular attraction. Its name means 'three-horned face'. Triceratops was a herbivore. In 2010 a controversial theory was proposed that Triceratops was actually an immature form of Torosaurus, although this has yet to be proven.
Discovery
The first known Triceratops remains were found in 1887 near Denver, Colorado. Fossil remains indicate that it lived across much of North America, sharing much the same territory as Tyrannosaurus rex.
Paleoecology
Triceratops lived in a range of ecologies including subtropical inland and coastal regions, and semi-arid plains.
