Revised identification of a reported Iguanodon-grade ornithopod tooth from the Scollard Formation, Alberta, Canada

An isolated tooth from the late Maastrichtian strata of the Scollard Formation of Alberta, Canada, has been identified as the only record of a non-hadrosaurid hadrosauriform from the Maastrichtian of North America. Here, we demonstrate that this identification is in error and that the tooth pertains to an indeterminate ceratopsid. In addition, we provide full documentation of the published collection of Scollard Formation fossils from which the tooth was originally derived.
