Polyodontosaurus

many-toothed lizard

• polys · Greek · many
• odous (odont-) · Greek · tooth
• sauros · Greek · lizard

The name combines Greek words for "many", "tooth" and "lizard", so it means "many-toothed lizard". It refers to the numerous small teeth of the type material, which are a hallmark of troodontid theropods. Its only species, Polyodontosaurus grandis, is now generally treated as the same animal as Troodon.
