Squaloziphius is an extinct genus of odontocete cetacean from the Early Miocene (Aquitanian) aged marine deposits in Washington State. It was originally classified as the most primitive beaked whale, being placed in a separate subfamily, Squaloziphiinae,^[1] (followed by Fordyce and Muizon 2001^[2]) but later authors have placed it outside Ziphiidae as either Odontoceti incertae sedis or closely related to Ziphiidae.^[3]^[4]
