Incakujira is an extinct genus of rorqual from the Late Miocene (Huayquerian in the SALMA classification) Pisco Formation in western Peru.^[1]

Description[]

The holotype specimen in Gamagori, Japan

Incakujira differs from other rorquals (fossil and extant) in having a less attenuated rostrum and the features of the maxilla, supraorbital, and remainder of the cranium. Kujira in the genus name means "whale" in Japanese.^[2]

Biology[]

The twisted postglenoid process of the squamosal suggests that the lunge-feeding capabilities of Incakujira were not as great as those of extant rorquals, and that Incakujira itself also pursued additional krill-feeding strategies like skimming.^[3]
