There may be an additional undescribed species at the Calvert Cliffs of Maryland, and there are possibly other species of squalodon … Squalodontidae is derived from the word "Squalodon", literally meaning "shark tooth". I spent the next 2 months learning techniques for cleaning and repairing fossils, while Frank tutored my on cetacean anatomy. the other relatives of the genus were related to modern cetaceans is suggest that Squalodon were very successful. Finally, in 2005 I formally published "A new species of Squalodon (Mammalia, Cetacea) from the Middle Miocene of eastern North America". Squalodon Size: Uncertain, multiple species are named, but Unlike other whales which have peg-like teeth, those of squalodontids were serrated like a sharks.
