Eotrachodon orientalis is a species of hadrosaurid that was described in 2016. The holotype has been found in the Mooreville Chalk Formation in Alabama with an exceptionally well-preserved skull, making it a rare find among dinosaurs of Appalachia. A phylogenetic study has found Eotrachodon to be the sister taxon to the hadrosaurid subfamilies Lambeosaurinae and Saurolophinae. This along with the other Appalachian hadrosaur Hadrosaurus suggests that Appalachia was the ancestral area of Hadrosauridae.[1]
