Naam beteken: “dawn rough tooth”1

Eotrachodon was an early duck-billed dinosaur that lived in what is now Alabama, USA. It had a long snout and hundreds of teeth for chewing plants. This dinosaur helps scientists understand how duck-billed dinosaurs evolved.2

Prettige feite

Eotrachodon is the oldest known duck-billed dinosaur from eastern North America.2

Its name means 'dawn rough tooth' because it was an early hadrosaur with rough teeth.1

The only fossil found was a young animal that was still growing when it died.2

Eotrachodon lived about 83 to 84 million years ago during the Santonian stage.2

Its skull had a special three-part depression around the nostril, which is a unique feature.2

This dinosaur was found in marine rocks, meaning its body was washed into the sea after death.2
