 Iguanodon was recorded from Africa based on teeth from Tunisia and elsewhere in the Sahara , but the description of Lurdusaurus and Ouranosaurus cast doubt on African records of Iguanodon . The genus was also recorded from Mongolia based on the description of I. orientalis , and in North America based on I. ottingeri from Utah . Another North American species , from South Dakota , once assigned to Iguanodon as I. lakotaensis , has since been reclassified as the genus Dakotadon .
