Utuntu dushimishije

1

Dakotadon was first thought to be a species of Iguanodon, but in 2008 scientist Gregory S. Paul gave it its own genus name.1

2

The only known fossil of Dakotadon is a partial skull and some vertebrae, found by a family who kept it in their garage for years.1

3

Dakotadon had a long, low skull with large nostril openings and a deep maxillary process of the premaxilla, making it more primitive than other iguanodonts.2

4

Scientists are not sure exactly how old the Dakotadon fossil is, but it likely lived during the late Valanginian to early Barremian stages of the Early Cretaceous.1

5

The name Dakotadon honors the Lakota people and the Dakota region where the fossil was discovered.1

6

Dakotadon's skull shows it had 19 tooth positions in its upper jaw, which is fewer than some related dinosaurs.2

Ishusho yakozwe na AI yerekana uko Dakotadon ishobora kuba yari isa, yakozwe na mudasobwa hashingiwe ku byo abahanga bazi. Ni ugukeka gusa: inyamaswa nyayo ishobora kuba yari isa ukundi, kandi nta muntu uzi amabara yayo nyayo.

The fossil was found by Louis Rossow in South Dakota in the 1980s and later donated to the South Dakota School of Mines and Technology. It was named Iguanodon lakotaensis in 1989 by David B. Weishampel and Philip R. Bjork, and renamed Dakotadon by Gregory S. Paul in 2008.1

Scientists still debate exactly where Dakotadon fits in the dinosaur family tree, because only a partial skull and some vertebrae have been found.12
