Eotrachodon is one of the earliest known members of the hadrosaur, or “duck-billed dinosaur,” family. Discovered in Alabama, this Late Cretaceous herbivore lived roughly 83 million years ago, during the Santonian stage. Its name means “dawn rough-tooth,” reflecting its status as an early relative of later, more famous hadrosaurs like Edmontosaurus and Parasaurolophus.

Measuring around 25 feet (7.5 meters) in length, Eotrachodon displayed the hallmark traits of its lineage in development — broad, flattened snout, hundreds of tightly packed teeth for grinding vegetation, and a powerful tail for balance and locomotion. Fossil evidence, including a remarkably complete skull, shows that Eotrachodon retained primitive features linking it to the earliest duck-billed dinosaurs from western North America and Asia.

Its discovery in the Eastern United States offers key evidence that hadrosaurs originated in North America before spreading to other continents, a vital clue in understanding the evolutionary history of this successful dinosaur group.
