Squalodelphis is an extinct genus of river dolphin from the early Miocene belonging to Squalodelphinidae, containing only its type species Squalodelphis fabianii.[1] Known remains have been found in Italy and Germany.[2][1]
Taxonomy
[edit]Squalodelphis is the type genus of the family Squalodelphinidae, which also includes the genera Huaridelphis, Notocetus, Phocageneus, Macrosqualodelphis, Medocinia, and Furcadelphis.[3] Throughout its history, it has been moved several times between Squalodelphinidae (previously Squalodelphidae) and Ziphiidae.
Description
[edit] | This section may be too technical for most readers to understand. (July 2025) |
Squalodelphis differs from Huaridelphis and Macrosqualodelphis in having a dorsal opening of the mesorostral groove broader than that of the premaxilla in the rostral base and lower tooth count, and from Macrosqualodelphis in having a transversely narrower nuchal crest as well as the left and right frontals being of unequal length at the vertex.[4]
Distribution
[edit]The type species of Squaloziphius, S. fabianii, is known from the Libano sandstone formation, in the Veneto region of northeastern Italy.[2][5] Fossils have also been found in the Baltringen region of Germany.[1]
