Unraveling the Mysteries of the Achelousaurus
When we think of Ceratopsians, the Triceratops are the first beasts that most of us imagine. If we don’t think of that dinosaur, we may picture a Diabloceratops, the Styracosaurus, or the Centrosaurus. However, most of us may not have named the Achelousaurus or even heard of this prehistoric beast. Let’s explore some dino facts and unravel the mysteries of the Achelousaurus.
What Was the Achelousaurus?
The Achelousaurus was an herbivorous dinosaur that lived in what is now Montana in the United States during the Late Cretaceous Period. This member of the Ceratopsian group was part of the subfamilies of Centrosaurinae. A subfamily is a smaller category existing within a group that shares specific traits; this helps scientists further study specific animals.
For example, all Ceratopsians had horns and walked on all fours. However, members of the Centrosaurinae subfamilies had shorter frills than their Chasmosaurines relatives, like the Triceratops, and their frills often had bony lumps (also known as “bosses”) or spikes ornamenting them.
Dino Fact
Scientists still don’t know why the Achelousaurus developed bosses, and the use of those bodily features remains unknown.
What Did the Achelousaurus Look Like?
Fossil records indicate that the Achelousaurus was around 6 meters long, with its head measuring around 1.5 meters. Like other Ceratopsians, fossil evidence of its skull indicates that it had a beak-shaped mouth and only had two horns on the top of its frill. Moreover, the Achelousaurus has bosses above its eyes and nose, giving its skull a distinct look.
What Does Achelousaurus Mean?
As we unravel the mysteries of the Achelousaurus, one of the most fascinating stories comes from its name. A dinosaur’s name often tells us about its physical traits, who found it, where it lived, or a mix of several. The Achelousaurus stands out because its name comes from the river god in Greek mythology—Achelous. According to myth, Hercules ripped one of Achelous’s horns off after the Greek god transformed into a bull.
How does this story relate to the prehistoric reptile? The Achelousaurus lacked a nose horn, a feature most Ceratopsians have, and has large bony bumps above its eyes and nose. It looks like the horn was ripped off, just like in the myth. This may have inspired its name and added an interesting layer to its discovery.
Dino Fact
Many paleontologists theorize that mythical beings, such as Achelous or the existence of dragons, actually emerged from ancient civilizations, which discovered fossils and assumed they belonged to fantastical creatures.
