Styracosaurus

With a head like that, we must be looking at a Styracosaurus.

The fossil record shows a bonebed of what was assumed to be a herd of these animals, but from what I’ve found they're far more antisocial than expected... Perhaps a result of modern climate conditions or irregularities in the genome? I'll leave that up for you to decide.

Styracosaurus belongs to a group of ceratopsians called centrosaurines, which tend to have longer nasal horns, shorter brow horns, and spiny frills. The famous Triceratops, in contrast, belongs to the chasmosaurines, which instead favor longer brow horns and long, simple frills.

The purpose of those gorgeous frills has long vexed paleontologists. Were they primarily for display? Temperature regulation, or neck protection? Now that we have one in the flesh, hopefully we can solve this mystery once and for all!
