It took a third and much more complete skull to change his mind.Īlthough not confidentially assignable, fossils possibly belonging to Triceratops were described as two taxa, Agathaumas sylvestris and Polyonax mortuarius in 18 respectively, by Marsh’s rival Edward Drinker Cope. He realized that there were horned dinosaurs by the next year, which saw his publication of the genus Ceratops from fragmentary remains, but he still believed B. alticornis to be a Pliocene mammal. This specimen was sent to Marsh, who believed that the formation from which it came dated from the Pliocene, and that the bones belonged to a particularly large and unusual bison, which he named Bison alticornis. The first named fossil specimen now attributed to Triceratops is a pair of brow horns attached to a skull roof, found by George Lyman Cannon near Denver, Colorado, in the spring of 1887. Illustration of specimen YPM 1871E, the horn cores that were erroneously attributed to Bison alticornis, the first named specimen of Triceratops 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. Specimens representing life stages from hatchling to adult have been found. Triceratops has been documented by numerous remains collected since the genus was first described in 1889 by American paleontologist Othniel Charles Marsh. This view has been disputed further data is needed to settle the debate. Research published in 2010 concluded that the contemporaneous Torosaurus, a ceratopsid long regarded as a separate genus, represents Triceratops in its mature form. Two species, T. horridus and T. prorsus, are considered valid today, from the seventeen species that have ever been named. Triceratops was traditionally placed within the "short-frilled" ceratopsids, but modern cladistic studies show it to be a member of the Chasmosaurinae which usually have long frills. More recent interpretations find it probable that these features were primarily used in species identification, courtship, and dominance display, much like the antlers and horns of modern ungulates. ![]() Traditionally, these have been viewed as defensive weapons against predators. The functions of the frills and three distinctive facial horns on its head have long inspired debate. 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. It was also one of the largest, up to 8–9 metres (26–30 ft) long and 5–9 metric tons (5.5–9.9 short tons) in body mass. The name Triceratops, which literally means 'three-horned face', is derived from the Greek words trí- ( τρί-) meaning 'three', kéras ( κέρας) meaning 'horn', and ṓps ( ὤψ) meaning 'face'.īearing a large bony frill, three horns on the skull, and a large four-legged body, exhibiting convergent evolution with bovines and rhinoceroses, Triceratops is one of the most recognizable of all dinosaurs and the most well-known ceratopsid. It is one of the last-known non-avian dinosaur genera, and became extinct in the Cretaceous–Paleogene extinction event 66 million years ago. 'three-horned face') is a 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.

And you shall flee as you fled from the earthquake in the days of Uzziah king of Judah. And you shall flee to the valley of my mountains, for the valley of the mountains shall reach to Azal. On that day his feet shall stand on the Mount of Olives that lies before Jerusalem on the east, and the Mount of Olives shall be split in two from east to west by a very wide valley, so that one half of the Mount shall move northward, and the other half southward. Then the Lord will go out and fight against those nations as when he fights on a day of battle. Half of the city shall go out into exile, but the rest of the people shall not be cut off from the city. For I will gather all the nations against Jerusalem to battle, and the city shall be taken and the houses plundered and the women raped.
