Squalodontidae closely related to the South Asian river dolphin ("Platanista gangetica"). The genus "Squalodon" was named by French naturalist Jean-Pierre Sylvestre de Grateloup in 1840 based on a jaw fragment he thought belonged to a reptile. Fossils discovered later, nevertheless, showed that this was a toothed whale. In extant odontocetes, however, the dentition is atavistic with all teeth reduced to simple, undifferentiated conical shapes. In squalodonts the teeth resemble those of the archaic whales, Archaeoceti, with conical incisors anteriorly and low-crowned, serrated teeth posteriorly. Squalodontidae Squalodontidae or the shark-toothed dolphins is an extinct family of large toothed whales who had long
Endangered Species Act of 1969 Endangered Species Preservation Act of 1969 was largely an expansion of the Lacey Act of 1900. In 1969, it was amended to protect species beyond game and wild birds. It granted protection to amphibians, reptiles, mollusks, and crustaceans, groups previously unprotected by any U.S. law.

The act then allowed for species on the domestic list to be given extra protection by United States agencies
