Incakujira (meaning Inca whale) is a genus of rorqual whales that lived during the Late Miocene epoch in what are now the coasts of Peru, about 8 million to 7.3 million years ago. It contains a single species, Incakujira anillodefuego, named and described in 2016 with known specimens coming from the Pisco Formation.

Description

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.^[1]

Paleobiology

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.^[1]
