Located in South Dakota, the name of the formation is derived from the Lakota Native American tribe.There are two units of the Lakota Formation, the Chilson Member (upper Berriasian to Valanginian) and the underlying Fuson Member (upper Valanginian to early Barremian). A Berriasian-Valanginian age for the Chilson Member has been extrapolated by means of ostracods and charophytes.[1]Vertebrate paleofauna[edit]Dinosaurs[edit]Dinosaurs reported from the Lakota FormationGenusSpeciesLocationStratigraphic positionMaterialNotesImagesDakotadon[2]D. lakotaensisChilson Member“Skull, mandible, [and] vertebrae.”[3]An ankylopollexian iguanodontHoplitosaurusH. marshiChilson Member“Partial postcranial skeleton [and] osteoderms.”[4]An ankylosaur belonging to PolacanthidaeOsmakasaurus[5][6]O. depressusChilson MemberPortions of both ilia, anterior part of the blade of one pubis, an incomplete sacrum, centrum of the last sacro-dorsal, 12 caudal vertebrae, 1 thoracic rib and many fragmentsAn ankylopollexian iguanodontMacronaria[7]IndeterminateChilson MemberLeft humerus and right metacarpal IA macronarian related to CamarasaurusMammals[edit]Turtles[edit]Turtles reported from the Lakota FormationGenusSpeciesLocationStratigraphic positionMaterialNotesImagesLakotemys[9]L. australodakotensisChilson MemberTwo shells and a partial skullA baenid paracryptodireOther vertebrate remains found within the Lakota Formation include a fish scale from the gar Lepisosteus and a crocodile tooth [10]References[edit]^ Sames, B.; Cifelli, R.
