Eotrachodon (meaning “dawn Trachodon”) is a genus of hadrosaurid dinosaur that lived in the Late Cretaceous of eastern North America. The holotype was found in the Mooreville Chalk Formation (Upper Santonian) of Alabama in 2007 and includes a well-preserved skull and partial skeleton, making it a rare find among dinosaurs of Appalachia.
