       Features of this cetaceans fossils indicate that Mammalodon was a baleen whale,‭ ‬although surprisingly it did not actually have baleen but instead well-developed teeth.‭ ‬Since it could not feed like baleen whales,‭ ‬Mammalodon must‭ ‬have done something different although what is uncertain.‭ ‬There is however one theory that suggests Mammalodon may have sifted through soft sediment such as mud while others consider it an open water predator.‭ ‬Mammalodon is the type genus of the Mammalodontidae and was the only member of this group until the description of Janjucetus in‭ ‬2006.
