Iberodon
Iberodon is a small, extinct mammal of the Lower Cretaceous from Portugal. It was a member of the also extinct order Multituberculata, and led its obscure and plant-eating existence in the company of dinosaurs. It lies within the suborder " Plagiaulacida" and family Pinheirodontidae.
The genus Iberodon was named by Hahn G. and Hahn R. in 1999 based on a single species. The species, known as Iberodon quadrituberculatus, is known from teeth found in Berriasian (Lower Cretaceous)-age strata of Portugal.
