Eoraptor

Eoraptor was one of the earliest dinosaurs, scampering around what is now Argentina over 230 million years ago. This small, nimble creature had a mix of different teeth, hinting it wasn't picky about its meals.

• Lived during the Late Triassic, about 231 to 228 million years ago.
• Discovered in 1993 from nearly complete fossil skeletons.
• Its varied teeth suggest it ate both plants and meat.
