Incakujira fordycei

Incakujira fordycei is an extinct rorqual of the late Miocene, the second species of the genus Incakujira, recognised in 2024. Its holotype comes from the Aguada de Lomas locality of the Pisco Formation of Peru, where it was recovered in 1987 by the Black Hills Institute of Geological Research and later passed to the Gunma Museum of Natural History in Japan, and it was preserved alongside the teeth of the shark Cosmopolitodus hastalis. The specimen is a young animal, an old calf or a young subadult, with a skull 2.377 metres long, a preserved skeleton of 9.22 metres and an estimated total length of up to 10.47 metres, which suggests that the species may have been larger on average than Incakujira anillodefuego. It honours the paleontologist Robert Ewan Fordyce, and the proportions of its vertebrae suggest a swimmer built for maneuverability that may have eaten both zooplankton and schooling fish.
