Karanisiais an extinct genus ofstrepsirrhineprimatefrom middleEocenedeposits inEgypt.
Classification[edit]
Two species are known,K. clarki[1][2]andK. arenula.[3]Originally considered acrownlorisid,more comprehensivephylogenetic analysessuggest it is a morebasalto crown lorisiformes.[4][5]
K. clarkiwas described in 2003 from isolated teeth and jaw fragments found in Late MiddleEocene(c.40 million years ago) sediments of theBirket Qarun Formationin the EgyptianFaiyum.[6][7]The specimens indicate the presence of atoothcomb,making it the earliest fossil primate to indisputably bear this trait, which is unique to all livingstrepsirrhines(lemurs,lorises,andgalagos).[7]
In 2010 a second species,K. arenula,was described in the journalNaturefrom Late MiddleEocenerocks inLibya.[3]
