When Dr. Caleb Brown first saw a nearly intact skull of a newly discovered Triceratops relative, he instantly knew that he was dealing with something special.
Discovered in Alberta, Canada, the Regaliceratops peterhewsi specimen sports a distinct frill, comprised of a crown-like arrangement of pentagonal plates radiating from its head. R. peterhewsi
is also equipped with two "comically small" horns over its eyes,
prompting Brown and his team to nickname the specimen "Hellboy", after
the famous horned comic book character.
"Many horned-dinosaur researchers who visited the museum did a double
take when they first saw it in the laboratory," said Brown.
Perhaps more importantly, R. peterhewsi is also giving
researchers an unprecedented look into the evolutionary history of
horned dinosaurs. There are two different classifications of horned
dinosaurs: Chasmosaurines and Centrosaurines. Although officially
classified as a Chasmosaurine, R. peterhewsi exhibits some characteristics of a Centrosaurine.
According to Brown, R. peterhewsi represents the first
example of evolutionary convergence, a process through which two
different groups independently developed similar features.
"This discovery also suggests that there are likely more horned
dinosaurs out there that we just have not found yet, so we will also be
looking for other new species," he added.
