Facts for Both Creatures:
Arktocara was an ancestor to modern river dolphins that lived in Oligocene Alaska. Unlike modern river dolphins it spent less time in freshwater and was likely still a majority sea dwelling cetacean. It had an elongated neck that allowed it to quickly grab squid without sacrificing too much of its field of vision.
Albicetus was a Macroraptorial Sperm Whale from the Miocene that was unique in that it had very large dental sockets to hold large teeth despite the fact it was fairly small by sperm whale standards. It may have competed with Brygmophyseter and other sleek shakes for food and territory.
