Notocetus is an extinct genus of river dolphin belonging to Squalodelphinidae. Known specimens have been found in Early Miocene marine deposits from Argentina, Italy and Peru.[1][2]
Taxonomy[edit]
Notocetus was unnecessarily given the replacement name Diochoticus by Ameghino (1894) on the false assumption that Notocetus was preoccupied by Notiocetus. Lydekker (1894), meanwhile, erected Argyrodelphis for the same specimen.[3][4] The type species of Otekaikea was once considered a species of Notocetus before being recognized as belonging to Waipatiidae.[5][6]
Distribution[edit]
Fossils of Notocetus have been found in:[7]
- Monte León Formation, Argentina
- Pietra Leccese Formation, Italy
- Chilcatay Formation, Peru
