Daily Dose of Prehistory Revival 5: Zygophyseter varolai

Zygophyseter varolai, often known as the Killer Sperm Whale, was a macroraptorial sperm whale that lived in what is now the Mediterranean, Black, Aral, and Caspian seas during the Late Miocene, about 11.6 to 7.6 million years ago. Measuring up to 23ft, Zygophyseter would've behaved much like a modern killer whale, hence the name, preying in large fish, cephalopods, seals, and smaller whales and dolphins. It had a domed head housing the spermaceti organ and the melon as well as a beak like several other macroraptorial sperm whales. Unlike modern sperm whales but like their cousins, Zygophyseter had large, conical teeth on both jaws which it used to great effect on its prey. In life it would've competed with tiger sharks and the massive Carcharocles megalodon for food.

YEAH BOI!
