What is "kabirmys"

Kabirmys is an extinct genus of anomaluroid (scaly-tailed flying squirrel) rodent from the earliest late Eocene of the Birket Qarun Formation from northern Egypt. It was described in September 2010 by Hesham Sallam, Erik Seiffert, Elwyn Simons, and Chlöe Brindley based on isolated teeth, partial mandibles, and an edentulous partial maxilla. It is noteworthy for being the largest known Eocene anomaluroid.
