Orycteropodidae is a family of afrotherian mammals. Although there are many fossil species, the only species surviving today is the aardvark, Orycteropus afer. Orycteropodidae is recognized as the only family within the order Tubulidentata, so the two are effectively synonyms.[1][2]

The family arose in Africa in the Early Miocene Epoch, and spread to Eurasia later in the Miocene. Most of the family's diversity had become extinct by the end of the Pliocene.[1]

Characters

A few anatomical characters unite the Orycteropodidae and Tubulidentata.

* the occipital region has extensive mastoid exposure
* the teeth have a distinctive structure called tubulidentate microstructure
* the femur has a pectineal tubercle
* the diaphysis of the tibia is curved mediolaterally
