Special Edition Triceratops Postcards (14.8 x 10.5 cm), hand numbered and hand signed are now available. An ink drawing of the Triceratops occupies the front and on the reverse is a short description of a Triceratops with a section for a stamp and address. As most of the content of this website is of a premium nature I thought it would be good to offer a limited edition at a very affordable price.
Bearing a large bony frill and three horns on its large four-legged body, and possessing similarities with the modern rhinoceros, Triceratops is one of the most recognizable of all dinosaurs and the best known ceratopsid. It shared the landscape with and was probably preyed upon by Tyrannosaurus, though it is less certain that the two did battle in the manner often depicted in traditional museum displays and popular images.
The functions of the frills and three distinctive facial horns on its head have long inspired debate. Traditionally, these have been viewed as defensive weapons against predators. More recent theories, noting the presence of blood vessels in the skull bones of ceratopsids, find it more probable that these features were primarily used in identification, courtship and dominance displays, much like the antlers and horns of modern reindeer, mountain goats, or rhinoceros beetles. The theory would find additional support if Torosaurus was found to be the mature form of Triceratops, as this would mean the frill also developed holes (fenestrae) as individuals reached maturity, rendering the structure more useful for display than defense.
