The use of the exaggerated structures to enable dinosaurs to recognize their own species has been questioned, as no such function exists for such structures in modern species. Each of the four growth stages were found to have identifying features. Az 1990-es évek második felében megtalált Zuniceratops a legkorábbi ismert, szemöldökszarvakkal rendelkező ceratopsia, a 2005-ös Yinlong pedig az első jura időszaki ceratopsiaként vált ismertté. In 1889, he named two species.  There is evidence that Tyrannosaurus did have aggressive head-on encounters with Triceratops, based on partially-healed tyrannosaur tooth marks on a Triceratops brow horn and squamosal; the bitten horn is also broken, with new bone growth after the break.
Additionally, although pitting, holes, lesions, and other damage on Triceratops skulls (and the skulls of other ceratopsids) are often attributed to horn damage in combat, a recent study finds no evidence for horn thrust injuries causing these forms of damage (for example, there is no evidence of infection or healing).  A Triceratops 8 meters (26 ft) long has been estimated by Gregory S. Paul to have massed 9 metric tons (9.9 short tons).  This stance can be seen in paintings by Charles Knight and Rudolph Zallinger. It is also believed that the two were involved in many long-standing battles against each other. Confusion stemmed mainly from the combination of short, solid frills (similar to that of Centrosaurinae), and the long brow horns (more akin to Ceratopsinae, also known as Chasmosaurinae). This suggestion is supported by the fact that the horns and frill of Triceratops changed shape dramatically throughout its development, allowing juveniles to be differentiated from more mature animals. Triceratopswas one of the last ceratopsians, and at maximum size, it was 29 feet (9 meters) long, 9.8 feet (3 meters) tall and 6 tonnes in weight.  Furthermore, the bird-hipped dinosaurs, Ornithischia, have been designated as all dinosaurs with a more recent common ancestor to Triceratops than modern birds..  However, he was largely ignored with John Ostrom, and later David Norman, both placing Triceratops within Centrosaurinae..
The brow horns penetrated the skin, but the blunt nose horn and the beak could not, and the front of the skull broke.
Science Supplies Missing Part! Other ceratopsids include Psittacosaurus, Centrosaurus, Protoceratops, Pachyrhinosaurus, Leptoceratops, Styracosaurus, and Montanoceratops. Fossils of “three-horned face,” as its Latin name is usually translated, date to the final 3 million years of the Cretaceous Period (145.5 million to 65.5 million years ago), making it one of the last of the non-avian dinosaurs to have evolved. , The skull also featured a pair of "brow" or supraorbital horns approximately 1 meter (3.3 ft) long, with one above each eye. , Like all chasmosaurines, Triceratops had a large skull relative to its body size.
Also, modern living creatures with such displays of horns and adornments use them in similar behavior. With Triceratops these were not particularly large and sometimes touched the quadratojugals.
The alphadontids Alphadon, Protalphodon, and Turgidodon, pediomyids Pediomys, Protolambda, and Leptalestes, the stagodontid Didelphodon, the deltatheridiid Nanocuris, the herpetotheriid Nortedelphys, and the glasbiid Glasbius all represent metatherians of the Hell Creek Formation. 136 Views. A Triceratops több videójátékban is megtalálható, például olyan, a Jurassic Park filmek alapján készült játékokban, mint az 1997-es Jurassic Park: Chaos Island.
However, recent years have been fruitful for the discovery of several dinosaurs related to ancestors of Triceratops. The discovery of many lone skeletal remains led officials to believe that these dinosaurs might have preferred to be solitary individuals.
As dinosaur fans know, Triceratops and Tyrannosaurus rex occupied the same ecosystem—the marshes and forests of western North America—about 65 million years ago, just before the K-T extinction that wiped out the dinosaurs. By Renciel Watch.
A Triceratops becsült hossza 7,9–9,0 méter, magassága 2,9–3 méter, a tömege pedig 6,1–12,0 tonna. Triceratops fossils date to the very end of the Cretaceous period, just before the K-T asteroid impact killed the dinosaurs. Alternatively, it may represent a distinct genus of horned dinosaur or a Triceratops with an unusual cranial morphology.
 The researchers also concluded that the damage found on the specimens in the study was often too localized to be caused by bone disease.  Ahogy a Triceratops egyre inkább a hosszú nyakfodrú Ceratopsinae alcsalád tagjának tűnik, annál valószínűbb, hogy az őse az 5 millió évvel korábban élt Chasmosaurusra hasonlított. The two main theories have revolved around use in combat, or display in courtship, with the latter thought now to be the most likely primary function. The front neck vertebrae were fused into a syncervical.  Továbbá madármedencéjű (Ornithischia) dinoszauruszoknak nevezik az összes olyan dinoszauruszt, amelynek újabb keletű közös őse van a Triceratopsszal, mint a modern madarakkal.. The dinosaur’s short toes probably terminated in small hooves. The largest adults are thought to have weighed 5,450–7,260 kg (approximately 12,000–16,000 pounds). Common Rare Untameable Cave The Triceratops (try-SAIR-uh-tops), or simply Trike, is one of the dinosaurs in ARK: Survival Evolved.  Indoklása szerint a hímek magasabb testtel, egyenesebb szarvakkal és hosszabb koponyával, a nőstények pedig kisebb koponyával és rövidebb, előre hajló szarvakkal rendelkeztek.
The remains are currently under excavation by paleontologist Peter Larson and a team from the Black Hills Institute.
 C. M. Sternberg made one modification, adding T. eurycephalus and suggesting that it linked the second and third lineages closer together than they were to the T. horridus lineage.
Az hogy melyik állat volt a támadó, nem állapítható meg. Lull and subsequent researchers would disagree as to the number of separate species (listed below), and came up with several phylogenetic schemes for how they were related to each other.
This, and other apparent healed wounds in the skulls of ceratopsians, has been cited as evidence of non-fatal intraspecific competition in these dinosaurs. At present there are two recognized species: T. horridus and T. prorsus. , One skull was found with a hole in the jugal bone, apparently a puncture wound sustained while the animal was alive, as indicated by signs of healing. The first named specimen now attributed to Triceratops is a pair of brow horns attached to a skull roof, found near Denver, Colorado in the spring of 1887. While several other genera of horned dinosaurs are known from bone bedspreserving bones from two to hundreds or thousands of individuals, to date there is only one documented bonebed dominated by Triceratops bones: a site in southeastern Montana with the remains of three juveniles. As one set of teeth wore down from constant chewing, they would be replaced by the adjacent battery, a process that continued throughout the dinosaur's lifetime. A harmadik és jóval teljesebb koponya megtalálása után azonban megváltozott a véleménye. In phylogenetic taxonomy, the genus has been used as a reference point in the definition of Dinosauria; Dinosaurs have been designated as all descendants of the most recent common ancestor of Triceratops and Neornithes (i.e. With a total number of 28 skulls studied, the youngest was only 38 centimeters (15 in) long. Zuniceratops, the earliest known ceratopsian with brow horns, was described in the late 1990s, and Yinlong, the first known Jurassic ceratopsian, in 2005.
Bár a tanulmányok valószínűként mutatják be ezt a tevékenységet, kérdéses, hogy, ha a ma élő szarvas állatokra nem jellemző, akkor vajon tényleg tettek-e ilyesmit.
1933-ban, és az összes ismert ceratopsiáról szóló 1907-es, mérföldkőnek számító Hatcher-Marsh-Lull-féle monográfia áttekintésében megtartotta a két csoportot és a két különálló fajt, egy harmadik, a T. obtusus és a T. hatcheri által képviselt, nagyon kis orrszarv jellemezte fejlődési vonallal együtt.
Lull, amikor először próbálta értelmezni a fajokat, két csoportot talált, de azt nem fogalmazta meg, hogy mi a különbség a kettő között: az egyikbe a T. horridus, a T. prorsus, és a T. brevicornus; a másikba pedig a T. elatus és a T. calicornis tartozik. , Chasmosaurines showed little variation in their postcranial skeleton. Groups of juvenile triceratops have been discovered in the Hell’s Creek formation in Montana, USA, and what appears to be a family group was found in 2012 in Wyoming, USA. Slightly larger juvenile specimens have backward-curving horns above the eyes and triangular epoccipitals bordering the large frill at the back of the skull. Most other frilled dinosaurs had large fenestrae in their frills, while the frills of Triceratops were noticeably solid. This suggests that the dinosaur’s entire head, aside from the cheeks and the area around the nostrils, was covered in keratin while it was alive. He tried to recover it by throwing a lasso around one of the horns.
Although Triceratops are commonly portrayed as herding animals, there is currently little evidence that they lived in herds.
Látható a Rareware által készített játékokban, például a Diddy Kong Racingben és a Starfox Adventuresben is. Common teeth previously referred to Dromaeosaurus and Saurornitholestes later were considered to be Acheroraptor. Triceratops was a herbivore.It lived in the Cretaceous period and inhabited North America.Its fossils have been found in places such as North Dakota, Wyoming and Saskatchewan (Canada).. Quick facts about Triceratops: Existed from 83.5 million years ago to Maastrichtian Age
Other early members of the horned, frilled dinosaur family may have been even smaller. A koponyát egy acélkeretre rögzítették, ezért nem volt lehetősége a rugalmas gerinc és a test izmai által biztosított elmozdulásra vagy hátrahúzódásra. While studies show that such activity would be feasible, if unlike that of present-day horned animals, there is disagreement about whether they did so.
