Anchiceratops is an extinct genus of ceratopsian dinosaur that lived during the Late Cretaceous period, approximately 74-70 million years ago. It was a medium-sized, heavily built, quadrupedal herbivore that could grow up to an estimated 6 meters in length. Anchiceratops was first discovered in 1914 by Barnum Brown and was named by Lawrence Lambe in 1917.
Anchiceratops is known for its distinctive frill, which is adorned with several large spikes and curved horns. It also had two long brow horns that projected forward from the top of its skull. The purpose of these horns is still debated among scientists, but it is believed that they were used for display or defense against predators. Anchiceratops had a beak-like mouth and was likely a selective feeder, preferring soft vegetation such as ferns and horsetails.
Despite its impressive appearance, Anchiceratops is not as well-known as other ceratopsians such as Triceratops. However, recent studies have shed new light on this intriguing dinosaur. Through the use of digital reconstruction techniques, scientists have been able to create detailed 3D models of Anchiceratops’ skull and frill, providing new insights into its anatomy and behavior.
Discovery and Naming
First Discovery
Anchiceratops is a genus of herbivorous ceratopsian dinosaur that lived during the Late Cretaceous period, about 72 to 71 million years ago. The first fossils of Anchiceratops were discovered in 1912 by Barnum Brown, an American paleontologist, in the Horseshoe Canyon Formation in Alberta, Canada. Brown was working for the American Museum of Natural History at the time, and he named the species Anchiceratops ornatus in 1914.
Etymology
The name Anchiceratops comes from the Greek words “anchi” meaning “near”, “keras” meaning “horn”, and “ops” meaning “face”. The name refers to the fact that Anchiceratops is closely related to Triceratops, but has a less developed frill. The specific epithet ornatus means “decorated” in Latin, referring to the ornate horns and frill of the dinosaur.
Overall, the discovery and naming of Anchiceratops by Barnum Brown has provided valuable insights into the evolution and diversity of ceratopsian dinosaurs during the Late Cretaceous period.

Anchiceratops was a medium-sized dinosaur that measured up to 4.5 meters (15 feet) in length and weighed around 1.5 tonnes (1.65 tons). Its heavily built body was adapted for ground-dwelling, and it had four sturdy legs that supported its weight.
Skull Characteristics
The skull of Anchiceratops was its most distinctive feature. It had two long brow horns and a short horn on the nose. The skull frill was elongated and rectangular, with edges adorned by coarse triangular projections. The frill extended out from the rear to the top of its head, providing protection to the neck and shoulders.
Horn and Frill Features
Anchiceratops had a short nose horn that went forward, and two long brow horns that curved backward. The frill was rectangular in shape and bordered by huge Epoccipitals. The frill was likely used for display purposes during mating season, as well as for protection against predators.
Overall, Anchiceratops was a heavily built, quadruple herbivore with an impressive skull and frill. Its size and build made it well-suited for ground-dwelling, and its distinctive features made it easily recognizable among other dinosaurs of its time.
Classification
Family and Genus
Anchiceratops is a genus of ceratopsian dinosaur that belongs to the family Chasmosauridae. This family is characterized by the presence of a frill on the back of the skull, which was adorned with various projections and horns. Anchiceratops was a medium-sized member of this family, with a length estimated to be around 4.3 meters. Its skull had two long brow horns and a short horn on the nose, and the frill was elongated and rectangular, with coarse triangular projections.
Evolutionary Relationships
Anchiceratops lived during the Late Cretaceous period, around 74 to 70 million years ago. It is known from fossils found in what is now Alberta, Canada. The genus is closely related to other ceratopsians such as Chasmosaurus and Triceratops, which are also members of the Chasmosauridae family. These dinosaurs were herbivorous and lived in herds, as evidenced by the discovery of multiple individuals in the same location.
Anchiceratops is an important genus for understanding the evolutionary relationships of ceratopsians. Its discovery and study have helped paleontologists to better understand the diversity of these dinosaurs and their adaptations to their environment. Despite its relatively small size, Anchiceratops was a fascinating and important member of the Late Cretaceous ecosystem.
Habitat and Distribution
Geological Period
Anchiceratops lived during the Late Cretaceous period, specifically the Early/Lower Maastrichtian epoch. This was around 74-70 million years ago.
Geographical Range
Anchiceratops fossils have been found in the province of Alberta, Canada. It is believed that the species lived in a coastal plain environment. The region was characterized by a warm and humid climate, with abundant vegetation and water sources. The species may have lived alongside other dinosaurs such as Edmontosaurus and Albertosaurus.
Anchiceratops is known to have been a herbivore, and it is likely that it fed on the vegetation that was abundant in its habitat. The species was a medium-sized dinosaur, growing up to an estimated 4.3 meters (14 ft) long. Its skull featured two long brow horns and a short horn on the nose. The skull frill was elongated and rectangular, its edges adorned by coarse triangular projections.
The fossils of Anchiceratops were first discovered in 1912 by Barnum Brown, a famous fossil hunter. Since then, about a dozen skulls of the genus have been found. The species was named by Brown in 1914 and was later described in more detail by Charles M. Sternberg in 1929. Today, the fossils of Anchiceratops can be found in several museums around the world, including the Royal Tyrrell Museum in Canada and the American Museum of Natural History in the United States.
Paleobiology
Diet
Anchiceratops was a herbivore, which means that it fed exclusively on plant material. The dinosaur had a powerful beak that helped it to bite through tough vegetation. It also had rows of teeth that were constantly replaced, allowing it to grind up its food more efficiently. It is believed that Anchiceratops fed on a variety of plants, including ferns, cycads, and conifers.
Social Behavior
Anchiceratops lived in herds, which is evidenced by the discovery of multiple individuals in the same location. The dinosaur likely lived in a matriarchal society, with the females leading the herd. This is supported by the fact that the females had larger frills than the males, which may have been used to attract mates or intimidate rivals.
Reproduction
Anchiceratops likely laid eggs like other dinosaurs. Fossilized eggs have been found in the same rock formations as Anchiceratops fossils, suggesting that they were laid by this dinosaur. It is believed that the eggs were buried in sand or soil, and the young hatched out of them after a few months. The young were likely born with a full set of teeth and were able to walk soon after hatching.
Fossil Record
Anchiceratops is known from several fossil sites in the Horseshoe Canyon Formation of Alberta, Canada. The fossils of Anchiceratops were first discovered in 1912 by Barnum Brown, an American paleontologist, and were later described as a new genus and species in 1914. Since then, several specimens have been found, including complete skulls, skeletons, and isolated bones.
Fossil Sites
The fossils of Anchiceratops have been found in the lower part of the Horseshoe Canyon Formation, which is estimated to be between 72.5-71 million years old. The formation is known for its diverse dinosaur fauna, including other ceratopsians such as Centrosaurus, Styracosaurus, and Pachyrhinosaurus. The Horseshoe Canyon Formation was deposited in a coastal plain environment, and the fossils of Anchiceratops were likely preserved in river channels or floodplain deposits.
Specimen Preservation
The specimens of Anchiceratops are generally well-preserved, with some specimens exhibiting excellent soft tissue preservation. The skulls of Anchiceratops are particularly well-known for their elaborate frills and horns, which were likely used for display or defense. The frills of Anchiceratops were composed of several bony plates that were fused together, and the horns were made of keratin, a tough protein found in hair and nails.
Overall, the fossil record of Anchiceratops provides valuable insights into the anatomy, behavior, and evolution of this unique dinosaur. By studying the fossils, paleontologists can reconstruct the life history of Anchiceratops and gain a better understanding of the Late Cretaceous ecosystems in which it lived.
