Eotrachodon

dawn Trachodon (dawn rough-tooth)

• eos · Greek · dawn, early
• trachys · Greek · rough
• odon · Greek · tooth

Eotrachodon combines the Greek "eos" (dawn) with "Trachodon", an old hadrosaur genus name meaning "rough tooth". The name signals that this duck-billed dinosaur is an early, primitive relative of hadrosaurids, and it was named for its resemblance to Trachodon-like hadrosaurs. The type species is Eotrachodon orientalis, with "orientalis" referring to its eastern North American origin.
