Richardoestesia is a morphogenus of theropod dinosaur teeth, originally described from the Late Cretaceous of what is now Canada, the United States and Kazakhstan. It currently contains two species, R. gilmorei and R. isosceles, and a possible third, R. asiatica. It has been used as a morphotaxon to describe other theropod teeth widely displaced in time and space from the type species. If all teeth assigned to the genus are truly reflective of the animals biology and taxonomic state, it would have been one of the longest lasting dinosaur genera, perhaps also being the most widely distributed.
