Karanisia

Karanisia is an extinct genus of lorisid primate and is represented by only one species, K. clarki. It was described from isolated teeth and jaw fragments found in Late Middle Eocene (c. 40 million years ago) sediments of the Birket Qarun Formation in the Egyptian Faiyum.

The specimens indicate the presence of a toothcomb, making it the earliest fossil primate to undisputably bear this trait, which is unique to Malagasy lemurs in extant primates. This fossil, along with recently discovered toothcomb-bearing Bugtilemur mathesoni (2001) of the Oligocene found in the Chitarwata Formation of Pakistan, has added complications to the puzzle of lemur origins.
