Iberica hahni
Iberica was a genus of multituberculate mammal from the Early Cretaceous Period. Its type and only species is I. hahni. Known specimens were found in the El Castellar Formation in Galve, Spain. While the fossils assigned to Iberica have been known since the 1960s, they were not officially named until 2011.
The name Iberica comes from the fossil's location on the Iberian Peninsula. The specific name hahni was named in honor of Gerhard and Renate Hahn for their research on Iberian Peninsula multituberculates.
Known fossils of I. hahni include seven P1/3s (premolars), which are the type specimen, as well as the referred material of a P4 fragment (premolar) and two M2s (molars). Its autapomorphies include the four cusps on its premolars, as compared to three cusps from related genera, as well as cuspules on the mesial and distal margins.
The material assigned to I. hahni, especially the referred P4 and M2s, cannot be certainly assigned to either Eobaataridae or Plagiaulacidae. The type premolars are similar to that of Parabolodon elongatus and Eobaatar? pajaronensis. The P4 fragment is also very similar to that of Cheruscodon balvensis. The tentative assignment to Eobaataridae seems somewhat unlikely.
