Triceratops
Triceratops is a genus of herbivorous ceratopsid dinosaur that first appeared during the late Maastrichtian stage of the late Cretaceous period, about 68 million years ago. Two species, T. horridus and T. prorsus, are considered valid today, from the seventeen species that have ever been named. Triceratops has been featured in film, postal stamps, and many other types of media.
