Boesse Posted January 21, 2015 Posted January 21, 2015 Definitely cetacean, although this would be a rather large odontocete; there are early pilot whales and beluga relatives in the Pliocene of California, as well as a small and poorly known sperm whale. However, there are also dwarf baleen whales (Herpetocetus) that have vertebrae in this size range.
