izinto ezimnandi

Iinyani ezimnandi

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

Umfanekiso owenziwe yi-AI: Eotrachodon — Umfanekiso owenziwe yi-AI obonisa indlela Eotrachodon esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

ubuzile

Eyona mibuzo ibuzwa kakhulu: Eotrachodon

?How big was Eotrachodon?

About 4 to 5.1 metres (13 to 17 feet) long. This is based on the only known fossil, which was a young animal that was still growing.2

?What did Eotrachodon eat?

It ate plants. It had a long snout and hundreds of teeth for chewing tough plant material.1 2

?When did Eotrachodon live?

It lived about 83 to 84 million years ago during the Late Cretaceous period.1 2

?Where was Eotrachodon found?

It was found in Alabama, USA, in a marine rock layer called the Mooreville Chalk Formation. Its body was washed into the sea after death.1 2

Ukufunyanwa: Eotrachodon was named in 2016 by Albert Prieto-Márquez, Gregory Erickson, and James Ebersole. The fossil was found in Montgomery, Alabama, in the Mooreville Chalk formation.4 2
Kusaxoxwa ngayo: Scientists are not sure how big Eotrachodon grew because the only known fossil is from a juvenile.2
