The unique horns of Allosaurus give them a rather sinister-looking grin.

Within those scowling eyes, there's a sclerotic ring - a bony structure that supports the organ's shape and musculature. I'm sure I'm wrong, but I can't stop thinking about what it would feel like to have the worst eyelash to ever get stuck in your eye... ... Maybe that's why they look so grim!

The intimidating expression is fitting, because Allosaurus in the Jurassic lived brutal lives. Paleontologists have found multiple fossils preserving broken bones, bone infections, and other conditions across their skeletons. Our Allosaurus will lead a much more pampered life. Hopefully this one will lighten up!

A fun name might make this one seem less intimidating. Perhaps we should call him Big Al - uh, Big Allie...? Shoot! Was this individual a male or female? It can be nearly impossible to sex reptiles by sight, dinosaurs included.
