Following Seiffert (2006), the Birket Quarun Formation of the Fayûm corresponds to the Priabonian with an upper bound of 33.9 Ma.

Fossil primates are relatively common mammalian fossils at many localities in North America and Eurasia throughout the Eocene; yet crown strepsirhines remain conspicuously absent prior to the late Eocene. Hence, we suggest the first appearance of euprimates, represented by Altiatlasius from the late Paleocene of Morocco (Sigé et al., 1990) as the soft maximum for Strepsirhini, namely 56 Ma ± 0.0 Myr = 56 Ma.

Phylogenetic analysis (Seffert et al., 2003) shows Karanisia is a member of crown Stresirrhini. It is loris-like, and has a dentition similar to the extant lorisid Arctocebus. Subsequent cladistic study (Seiffert, 2007) still could not place Karanisia unequivocally, and it was identified as either a stem lorisiform or a crown strepsirrhine of uncertain afﬁnities; in either case it is nested within crown Strepsirrhini.
