Eotrachodon orientalis (meaning "dawn Trachodon from the east") is a species of hadrosaurid that was described in 2016. The holotype was found in the Mooreville Chalk Formation (Upper Santonian) in Alabama in 2007 and includes a well-preserved skull and partial skeleton, making it a rare find among dinosaurs of Appalachia. Another primitive hadrosaur, Lophorhothon, is also known from the same formation, although Eotrachodon lived a few million years prior. 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 and possibly Lophorhothon, Claosaurus and both species of Hypsibema, suggests that Appalachia was the ancestral area of Hadrosauridae.

Uno studio filogenetico di Prieto-Marquez, Erickson e Ebersole (2016) ha indicato che Eotrachodon abbia notevoli affinità con le sottofamiglie Lambeosaurinae e Saurolophinae collocandosi però al di fuori di esse. Il seguente cladogramma mostra la tassonomia di Eotrachodon, secondo tale studio. Questo genere indicherebbe secondo gli autori citati che l'Appalachia (e non altre aree del mondo indicate da altri autori) sarebbe stata la culla ancestrale degli Adrosauridi. Il ritrovamento dei resti di questo animale suggerisce che l'animale vivesse in un ambiente costiero e/o che il suo corpo sia stato trascinato fino al mare. (it)

- Eotrachodon — род травоядных орнитоподовых динозавров семейства гадрозавров из верхнего мела Северной Америки. Это один из самых старейших и самый примитивный гадрозаврид, а также единственный известный гадрозаврид из Аппалачей (современный восток Северной Америки) с сохранившимся черепом. Типовой и единственный вид Eotrachodon orientalis назвали и описали Альберт Прието-Маркес и его коллеги в 2016 году. Родовое имя образовано от греческих слов «eos», что значит «начало», «исток» и «Trachodon», означающее «грубый зуб» (дань уважения первому описанному роду гадрозаврид, долгое время затем считавшемуся nomen dubium). Видовое имя orientalis означает «восточный» по месту обнаружения гадрозаврида — юго-восток Северной Америки. (ru)
