Triceratops

MAIN INFORMATION:Triceratops (/traɪˈsɛrətɒps/ try-SERR-ə-tops;[1] lit. 'three-horned face') is a genus of chasmosaurine ceratopsian dinosaur that lived during the late Maastrichtian age of the Late Cretaceous period, about 68 to 66 million years ago in what is now western North America. It was one of the last-known non-avian dinosaurs and lived until the Cretaceous–Paleogene extinction event 66 million years ago. The name Triceratops, which means 'three-horned face', is derived from the Greek words trí- (τρί-) meaning 'three', kéras (κέρας) meaning 'horn', and ṓps (ὤψ) meaning 'face'.

Physical Appearance: Triceratops, as pretty well known, is a Ceratopsian. It had a quadruple-legged massive body that was averaged about 8-9 meters long, and it had the iconic head, having a rough frill on the top, sets of three horns, two of which were situated on top of each eye of the Triceratops, and a third one on the snout. The Triceratops had a jaw and snout that closely resembled a beak, which were just very hard and used to bite onto plants, and which, they did have a normal mouth like humans, large, and situated inside the jaw.

Appearance: Triceratops would have a very saturated skin tone, have streaks of light yellow, light green and dark brown filling the body and head, the frill would have a distinctive pattern, it could be streaks of dark brown on red, and on yellow, but that did not tell the difference of a male or female. A sexual dimorphism that could be told against a male or female, is that the female's body scale would be slightly smaller than the male, and having horns on the frill that are pointed up and are also slightly shorter. The male would be large, highest at 9 meters, that have horns on the frill that are long, stretching out of the length of its head, and only pointed either slightly up, or narrowly down.

Paleontology: Triceratops is one of the most recognizable of all dinosaurs and the best-known ceratopsian. It was also one of the largest, measuring around 8–9 m (26–30 ft) long and weighing up to 6–10 t (5.9–9.8 long tons; 6.6–11.0 short tons). It shared the landscape with and was most likely preyed upon by Tyrannosaurus, though it is less certain that two adults would battle in the fanciful manner often depicted in museum displays and popular media. The functions of the frills and three distinctive facial horns on its head have inspired countless debates. Traditionally, these have been viewed as defensive weapons against predators. 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

Triceratops is the best-known genus of Ceratopsidae, a family of large, mostly North American ceratopsians. The exact relationship of Triceratops among the other ceratopsids has been debated over the years. Confusion stemmed mainly from the combination of a short, solid frill (similar to that of Centrosaurinae), with long brow horns (more akin to Chasmosaurinae).[40] In the first overview of ceratopsians, R. S. Lull hypothesized the existence of two lineages, one of Monoclonius and Centrosaurus leading to Triceratops, the other with Ceratops and Torosaurus, making Triceratops a centrosaurine as the group is understood today.[15] Later revisions supported this view when Lawrence Lambe, in 1915, formally describing the first, short-frilled group as Centrosaurinae (including Triceratops), and the second, long-frilled group as Chasmosaurinae.

Although Triceratops is commonly portrayed as a herding animal, there is currently little evidence to suggest that they lived in herds. While several other ceratopsians are known from bone beds preserving bones from two to hundreds or even thousands of individuals, there is currently only one documented bonebed dominated by Triceratops bones: a site in southeastern Montana with the remains of three juveniles. It may be significant that only juveniles were present.[49] In 2012, a group of three Triceratops in relatively complete condition, each of varying sizes from a full-grown adult to a small juvenile, were found near Newcastle, Wyoming. The remains are currently under excavation by paleontologist Peter Larson and a team from the Black Hills Institute. It is believed that the animals were traveling as a family unit, but it remains unknown if the group consists of a mated pair and their offspring, or two females and a juvenile they were caring for. The remains also show signs of predation or scavenging from Tyrannosaurus, particularly on the largest specimen, with the bones of the front limbs showing breakage and puncture wounds from Tyrannosaurus teeth.[50] In 2020, Illies and Fowler described the co-ossified distal caudal vertebrae of Triceratops. According to them, this pathology could have arisen after one Triceratops accidentally stepped on the tail of another member of the herd

Triceratops were herbivorous and, because of their low slung head, their primary food was probably low growing vegetation, although they may have been able to knock down taller plants with their horns, beak, and sheer bulk.[30][60] The jaws were tipped with a deep, narrow beak, believed to have been better at grasping and plucking than biting.[42][61]

Triceratops teeth were arranged in groups called batteries, which contained 36 to 40 tooth columns in each side of each jaw and 3 to 5 stacked teeth per column, depending on the size of the animal.[30] This gives a range of 432 to 800 teeth, of which only a fraction were in use at any given time (as tooth replacement was continuous throughout the life of the animal).[30] They functioned by shearing in a vertical to near-vertical orientation.[30] Additionally, their teeth wore as they fed, creating fullers that minimised friction as they masticated.[62] The great size and numerous teeth of Triceratops suggests that they ate large volumes of fibrous plant material.[63][64][65] Other plants that were apart of Triceratops's diet included Populus plants, Pine plants, Platanus plants, Hazel plants, and Taxodium plants.[66] Some researchers suggest it, along with its cousin Torosaurus ate palms and cycads[67][68][69] and others suggest it ate ferns, which then grew in prairies.[70][58] Studies of the isotopes of ceratopsian and hadrosaur teeth revealed that Triceratops and Edmontosaurus respectively engaged in niche partitioning.
