Regaliceratops lived during the Late Cretaceous period in Alberta, Canada and is an extinct genus of Ceratopsid dinosaurs. Its skull was discovered in 2005 by Peter Hews at the Oldman River, St. Mary River Formation, in Alberta. He found the skull sticking out of a rock/cliff above the river. Later, the specimen and all its remains were secured by a team of professionals from the Royal Tyrrell Museum. The name Regaliceratops is derived from the Latin word 'regalis' which means royal and the Greek words 'keras' and 'ops', which means horns and face, so its name roughly translates to 'royal horned face', it was named in 2015 by Donald Henderson and Caleb Marshall Brown. The species is recognized by its distinctive physical features like a simple crown-like frill, horn ornamentation, similar to Triceratops and other Chasmosaurines, but it can also be separated from them as they have a smaller or shorter frill. The specific name of this new species - Regaliceratops peterhewsi - honors Peter Hews, its discoverer.

Regaliceratops Interesting Facts

How do you pronounce 'Regaliceratops'?

The word Regaliceratops is pronounced as 'ree-gay-lih-ser-uh-tops'. Excavating the species proved to be a task for him and the team of researchers and excavators sent by the Royal Tyrrell Museum, the main reason for all the trouble caused was the hard rock the fossil was embedded in, digging carelessly would not only damage the valuable discovery but all the river which is a protected fish-breeding ground. Safely securing this specimen took years of hard work and patience and the experience by many was described as 'hellish', which also gave the specimen its nickname 'Hellboy'.

What type of dinosaur was a Regaliceratops?

Originally, Regaliceratops was classified as a member of the Triceratopsini by Brown and Henderson, but further studies conducted by Mallon and his team revealed otherwise. Ceratopsians are split into two primary groups Chasmosaurines and Centrosaurines. Peter Hews discovered the specimen near the rock formations, where another species called Eotriceratops xerinsularis from the Chasmosaurine was discovered, and given that Centrosaurines went extinct several million years before the Chasmosaurines appeared, its classification was made simpler.

In which geological period did the Regaliceratops roam the earth?

This dinosaur lived during the Cretaceous period, about 68 million years ago.

When did the Regaliceratops become extinct?

These dinosaurs went extinct during the K-T mass extinction nearly 65 million years ago.

Where did a Regaliceratops live?

Geologist Peter Hews discovered the skull belonging to an individual dinosaur near the Oldman River, St. Mary River Formation, Alberta in 2005. Thus, revealing that its range occupied regions of Canada.

What was a Regaliceratops' habitat?

This dinosaur lived near regions that provided it with plenty of food and water i.e. forests, riversides, floodplains, and swamps.

Who did a Regaliceratops live with?

Unfortunately, the social behavior and lifestyle of this species are still being researched. But many theories suggest that they were solitary.

How long did a Regaliceratops live?

Their life span is unknown. But these creatures had a long-lasting regen and roamed the Earth from the early Jurassic Period, until the end of the Cretaceous Period.

How did they reproduce?

They reproduced via sexual reproduction. Males would deposit their sperm inside females, who would later lay fertilized eggs containing developing dinosaur embryos. They built nests by digging burrows in the soil and laid giant eggs which had a hard layered shell. All the eggs were usually amniotic, meaning the fetus was covered by a membrane which helped in its protection as well as supplying oxygen and other nutrients to the fetus.

Regaliceratops Fun Facts

What did a Regaliceratops look like?

Horned dinosaurs are divided into two main groups the Centrosaurinae, whose members have a short frill, with a large nasal/nose horn, and shorter brow horns, and the second group is Chasmosaurinae, whose members have a long frill with a short nasal horn and longer brow horns, and a crown-like frill. The discovery of Regaliceratops' skull allowed paleontologists better understand the two groups. This new species of horned dinosaur with somewhat bizarre features was described by Caleb Marshall Brown and Donald Henderson, as species similar to the Chasmosaurine group, but with ornamentation more similar to Centrosaurines. Regaliceratops peterhewsi had three horns, the horns placed near its brows were larger than its nose horn. This dinosaur is considered as an 'odd animal that just has the face of a dinosaur', it is closely related to Triceratops, and other horned dinosaurs that belong to the Chasmosaurines group. Regaliceratops peterhewsi and its relatives are physically characterized by its distinctive brow horns, and the smaller horn on top of its nose, the frills, and its patterns are quite simple among this species, with a few plates around the edges, unlike the other groups of dinosaurs such as Ceratopsians and Centrosaurines, who have larger nose horns and no brow horns, and whose frills are adorned with spikes.

Fun facts about a Regaliceratops' skeleton discovered by Peter Hews.

How many bones did a Regaliceratops have?

How did they communicate?

Communication among these horned dinosaurs that roamed the Earth during the Late Cretaceous era is still a mystery but many scientists over the past decades have come up with several theories that suggest possible ways these animals communicated, some put forth the theory of vocalizations and that these ferocious beasts engaged in dialogue by producing calls, hoots, cracking sounds, body movements, and symbolic love calls during the mating season.

Scientists speculate that they were not aggressive in general but were good at defending themselves thanks to their horns.

Did you know...

Regaliceratops peterhewsi has a shield-like armor similar to other Triceratops but also has horns which are considered unusual and a symptom of an evolutionary phenomenon called convergent evolution. Convergent evolution is the process where different organisms evolve similar traits independently.

This new species of dinosaurs are believed to have first occurred sometime after the extinction of the Centrosaurines.

Did the Regaliceratops have sharp teeth?

Its teeth were adapted to its diet and helped it chew hard plant materials.

How did the Regaliceratops get its name?

Peter Hews, a geologist discovered a specimen, or to be more specific the skull of an individual member projecting out of a cliff near the Oldman River, St. Mary River Formation, Alberta, Canada in 2005. Followed by a team of experts from the Royal Tyrrell Museum, excavating the fossils. The specimen is recognized by its peculiar features such as its horns and was nicknamed 'Hellboy' for all the trouble and difficulty the recovery team had to face to make sure the fossils are recovered with no damage. The specific name Regaliceratops peterhewsi honors Peter Hews, and is also a reference to its unique crown-like frill, and was given to the species by Brown & Henderson. It is also referred to as the 'horned face dinosaur'.
