Lipotidae is a family of river dolphins containing the functionally extinct baiji and the fossil genus Parapontoporia.[1][2] The genus Prolipotes, which is based on a mandible fragment from Neogene coastal deposits in Guangxi, China,[3] has been classified as an extinct relative of the baiji, but is dubious.[4]
The putative kentriodontid "Lophocetus" pappus is a possible relative of Lipotidae.[5]
