Scaldicetus is an extinct genus of toothed cetacean related to sperm whales. Although widely used for a number of extinct physeterids with primitive dental morphology consisting of enameled teeth, Scaldicetus as generally recognized appears to be a paraphyletic assemblage of primitive physeteroids.^[1]

Taxonomy

The name Scaldicetus caretti was coined in 1867 for numerous physeteroid teeth collected in Neogene deposits near Antwerp, Belgium.^[2] Synonyms of Scaldicetus include Palaeodelphis, Homocetus, and Eucetus.^[3] The genus Physodon Gervais 1872 was previously considered a synonym, but it has been recently considered a nomen dubium.^[4]

"Ontocetus" oxymycterus, described from the middle Miocene (Langhian) of Santa Barbara, California, was assigned to Scaldicetus in 2008,^[5] but was subsequently made the type of a new genus, Albicetus.^[6]
