El nombre significa "cara con cinco cuernos", deriva del griego antiguo "penta/πέντα" que significa "cinco", "ceras/κέρας" "cuerno" y "-ops/ωψ" "cara",[5]​ en referencia a las dos grandes apófisis epiyugales que sobresalían de sus mejillas, que se sumaban a los tres cuernos típicos de los miembros de su subfamilia. Sullivan, R.M. In 1998 Thomas Lehman described OMNH 10165, a very large skull and its associated skeleton found in New Mexico in 1941. The size of the animal was no more than 8 meters long, while the height of this strange creature was a maximum of 400 centimeters, whose weight is estimated to have been more than 5 tons. This late Cretaceous ceratopsian was "diagnosed" at the turn of the 20th century by the famous paleontologist Othniel C. Marsh, on the basis on a single, two-horned skull lacking the characteristic nasal horn of Triceratops--and given the name Diceratops, by another scientist, a few years after Marsh's death. From Wikimedia Commons, the free media repository. Pentaceratops (five-horned face) is a genus of herbivorous ceratopsid dinosaur from the late Cretaceous Period of what is now North America. Pentaceratops. [7] This was later considered to be the same species as Pentaceratops sternbergii and thus a junior synonym, the hole being the likely effect of an injury. An interesting fact about Pentaceratops is that it looks very much like a rhinoceros, except for a few key differences. Apart from the San Juan Basin finds, a juvenile specimen of Pentaceratops, SDMNH 43470, was found in the Williams Fork Formation of Colorado in 2006. [13] The nose horn of Pentaceratops is small and pointing upwards and backwards. The rear dorsal vertebrae bear long spines from which ligaments possibly ran to the front, to balance the high frill. Pentaceratops is one of the largest Ceratopsians.It measured about 20 - 24 feet in length and weighed about 5 - 6.5 tonnes.It had the longest skull of any land vertebrate,measured upto 10.5 feet. Pentaceratops fossils were first discovered in 1921. Pentaceratops fossils were first discovered in 1921. The ischium is long and strongly curves forward. Provenían de la Formación Kirtland. Habría utilizado su pico agudo de ceratopsiano para arrancar las hojas o las agujas. Otros dinosaurios del mismo lugar incluían a Parasaurolophus cyrtocristatus, Prenocephale, Nodocephalosaurus y posiblemente al Daspletosaurus. It appears to be most closely related to Utahceratops. The other three AMNH specimens were AMNH 1624, a smaller skull; AMNH 1622, a pair of brow horns; and AMNH 1625, a piece of skull frill.[5]. ][clarification needed] and so it is likely that this dinosaur fed on the predominant plants of the era: ferns, cycads and conifers. It was pushing 7 tons- well over the twice as big as your typical Pentaceratops.That’s close to the huge Triceratops in size, making it one of the largest known horned dinosaur skeletons. He noted that the placement of Utahceratops does not make the genus paraphyletic, as there is no requirement that genera are monophyletic. Search Pentaceratops Skull. It was squat, walked on its four legs and had 3 horns on its face. The Williams Fork chasmosaur differs from the Pentaceratops and Utahceratops species, and might require a new specific or generic name.[17]. Titanoceratops was named for its large size, being one of the largest known horned dinosaurs and the type species was named T. ouranos, after Uranus (Ouranos), the father of the Greek titans. [5] The name had been suggested to Osborn by William Diller Matthew; the specific epithet served as a consolation to the almost bankrupt Sternberg whose 1923 fossils were initially not acquired by the museum that had to use its 1923/1924 budget to process the finds of the great Asian expeditions by Roy Chapman Andrews. [6], The holotype was the skull discovered by Sternberg in 1922, specimen AMNH 6325. Unlike some other horned, frilled dinosaurs, Pentaceratops has a fairly straightforward fossil history. A denizen to the wastelands of Extinction, Pentaceratops makes its home in the hostile wastelands of earth where it comes into constant contact with corrupted. Pentaceratops lived around 76–73 million years ago, its remains having been mostly found… La gola de Pentaceratops es más larga que la de Triceratops, con dos grandes ventanas en ella.

Pentaceratops ("five-horned face") is a genus of herbivorous ceratopsid dinosaur from the late Cretaceous Period of what is now North America. It was found in a layer of the Fruitland Formation, dating from the Campanian, about seventy-five million years old. Measuring 7.5 meters in its length and standing 2.5 meters tall, the Pentaceratops was one of the largest ceratopsid dinosaurs. It is the oldest known member of Triceratopsini. It is rectangular, adorned by large triangular osteoderms: up to twelve episquamosals at the squamosal and three epiparietals at the parietal bone. The initial remains (a skull and a piece of hipbone) were discovered in 1921 by Charles H. Sternberg, who continued plying this same New Mexico location over the next couple of years until he had collected enough specimens for his fellow paleontologist Henry Fairfield Osborn to erect the genus Pentaceratops. Pentaceratops was first discovered by Charles Hazelius Sternberg in 1921 near the San Juan Basin in New Mexico. He sent these fossils to paleontologist Carl Wiman. [1] Subsequent finds include specimens MNA Pl. File usage on other wikis; Metadata; Size of this preview: 775 × 599 pixels.

In 1921 he recovered a skull and a rump, specimens PMU R.200 and PMU R.286, at the Meyers Creek near the Kimbetoh Wash in a layer of the Kirtland Formation. The skull is very large but is oth-erwise similar to the type (AMNH 6325) and referred specimens of P. sternbergi (Lehman, 1993). Tenía una gola más grande que la de otros ceratopsiosy tres cuernos; era el de mayores dimensiones de la familia. Pentaceratops ("five-horned face") is a genus of herbivorous ceratopsid dinosaur from the late Cretaceous Period of what is now North America.

El cráneo y el esqueleto asociado se encuentra en exhibición en el Museo de Historia Natural Sam Noble de Oklahoma. 2006. In 1922 Sternberg decided to work independently and began a dig north of Tsaya Trading Post, in the Fossil Forest of San Juan County. The very thick jugal and the squamosal do not touch each other, a possible autapomorphy. The somewhat upward tilted frill of Pentaceratops is considerably longer than that of Triceratops, with two large holes (parietal fenestrae) in it. The genus was named in 1923 when its type species Pentaceratops sternbergii was described. The skull length of AMNH 1624 is 2.3 meters while PMU R.200 has a length of 2.16 meters. Its known maximum size is dependent on the identity of specimen OMNH 10165. C.

The first specimens were collected by Charles Hazelius Sternberg in the San Juan Basin in New Mexico. Working on commission for the Swedish Uppsala University, Sternberg recovered a skull and rump, specimens PMU R.200 and PMU R.286, at the Meyers Creek near the Kimbetoh Wash in a layer of the Kirtland Formation.
