Triceratops (Postage Stamp of 220 AMD - Armenian Dram):
The Postage Stamp of 220 AMD
Triceratops is an extinct genus of herbivorous chasmosaurine ceratopsid dinosaur that first appeared during the late Maastrichtian stage of the Late Cretaceous period, about 68 million years ago in what is now North America.
It is one of the last-known non-avian dinosaur genera, and became extinct in the Cretaceous–Paleogene extinction event 66 million years ago. The name Triceratops, (which literally means 'three-horned face'), is derived from Greek.
Bearing a large bony frill, three horns on the skull, and a large four-legged body, exhibiting convergent evolution with rhinoceroses and bovines, Triceratops is one of the most recognizable of all dinosaurs and the most well-known ceratopsid.
It was also one of the largest, up to 9.00 meters (29.50 ft) long and 12 metric tons in weight.
It shared the landscape with and was most likely preyed upon by Tyrannosaurus, though it is less certain that two adults did battle in the fanciful manner often depicted in museum displays and popular images.
As the archetypal ceratopsid, Triceratops is one of the most popular dinosaurs, and has been featured in film, postal stamps, and many other types of media.

Liopleurodon (Postage stamp of 280 AMD - Armenian Dram):
The Postage Stamp of 280 AMD
Liopleurodon (meaning 'smooth-sided teeth') is an extinct genus of large, carnivorous marine reptile belonging to the Pliosauroidea, a clade of short-necked plesiosaurs.
The two species of Liopleurodon lived from the Callovian Stage of the Middle Jurassic to the Kimmeridgian stage of the Late Jurassic Period (c. 166 to 155 mya).
It was the apex predator of the Middle to Late Jurassic seas that covered Europe. The largest species, L. ferox, is estimated to have grown up to 6.4 metres (21 ft) in length.
The name "Liopleurodon" (meaning "smooth-sided tooth") derives from Ancient Greek.
