Incakujira

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