Dakotadon

Dakotadon is a genus of iguanodont dinosaur from the Barremian-age Lower Cretaceous Lakota Formation of South Dakota, USA, known from a partial skull. It was first described in 1989 as Iguanodon lakotaensis, by David B. Weishampel and Philip R. Bjork.[1]  Its assignment has been controversial. Some researchers suggest that ''"I." lakotaensis was more basal than I. bernissartensis, and related to Theiophytalia,[2]  but David Norman has suggested that it was a synonym of I. bernissartensis''.[3] Gregory S. Paul, working on a revision of iguanodont species, gave "I." lakotaensis its own genus (Dakotadon) in 2008.[4]
