Colorful Pentaceratops - The Pentaceratops lived 75 million years ago in the southwestern United States. Herbivore, it was 8 meters long and weighed 6 tons. The usefulness of his collar is not clearly defined. A protective shield against predators is a possibility, but relatively fragile, it is likely that it was used as an attribute of visual intimidation to rivals or to attract opposing sex. Although no pigment of colour has been preserved in the fossil remains, it is not unreasonable to imagine that these collars may have been very coloured. A six ton, 27 foot long Pentaceratops wonders a Cretaceous forest 75 million years ago in what is today the southwestern United States. Like the better known Triceratops, Pentaceratops was a Ceratopsid, a large four-legged plant-eating dinosaur characterized by beaks, rows of shearing teeth in the back of the jaw, and elaborate horns and frills. While they resemble defensive shields, the frills are in fact relatively fragile, suggesting that they may have served a purpose other than protecting against a brute force attack. One possibility is that the frills were employed as visual displays in order to intimidate rivals and attract the opposite sex. While no color pigmentation has been preserved in the fossil remains of Ceratopsids, it's not unreasonable to suggest that they may have been very colorful, like many reptiles and birds today
