Asioryctitheria
Asioryctitheria ("Asian digging beasts") is an extinct order of early eutherians. Skull structure
With the exception of Prokennalestes, these advanced forms lacked a Meckelian groove. Furthermore, they were equipped with double-rooted canines, a lower premolar with a reduced or absent metaconid and a more elongated lower premolar than their predecessors. In addition, the entoconid and hypoconulid on the lower molars are untwinned, the entotympanic is non-existent, the alisphenoid is enlarged, a Vidian foramen is present as well as a promontorium linked to the paroccipital process via the crista interfenestralis. Classification
Asioryctitheria contains at least four genera and two families. Sasayamamylos kawaii Kusuhashi et al. 2013
