Kekenodon is an extinct kekenodontid early whale from the Late Oligocene (Chattian) of New Zealand. Measuring 8–9 m (26–30 ft) long, it was a large raptorial whale which hunted marine mammals and penguins.[1] Although at times classified as a basilosaurid, mysticete, or odontocete, recent work suggests that it represents a phylogenetic intermediate form between Basilosauridae and Neoceti.
Classification
[edit]Kekenodon was considered a member of the basilosaurid subfamily Dorudontinae in the classic monograph on Archaeoceti by Kellogg (1936).[2]
"Squalodon" gambierensis from Australia is a close relative of Kekenodon.[3]
Phylogenetic analysis suggests that Kekenodon is the "latest-surviving archaeocete, sister-taxon to the Neoceti."[1]
