Federicoanaya is an extinctgenus ofinteratheriinenotoungulates that lived during the LateOligocene in what is nowBolivia. Fossils of this genus have been found in theSalla Formation of Bolivia.[1]
The genus name,Federicoanaya, refers toFederico Anaya, known for his significant contributions to Bolivian paleontology. The specific name,sallaensis, refers to the Salla Formation where it was found.[1]
Federicoanaya was a small-sized interatheriid. It can be distinguished from other basal interatheriines such asProargyrohyrax andSantiagorothia, by having hypselodontcheek teeth an completely persistent lingual sulcus on the uppermolars. Its permanent upper dentition had thincementum.[1][2]Federicoanaya, along withBrucemacfaddenia, share upper cheek teeth with a median lobe and a labially extended parastyle in molars.[3]
Federicoanaya was first described in 2008 based on remains found in theSalla Formation, in theLa Paz Department, Bolivia, dating to the Late Oligocene, around 29 to 23 mya. It was described alongside another interatheriid,Brucemacfaddenia boliviensis. It is a basal member of theInteratheriidae family, more specifically within the subfamilyInteratheriinae.
The following cladogram of theInteratheriinae is based on Veraet al. 2017, showing the position ofFedericoanaya.[4]
