Hadrodelphis is an extinct genus of dolphin once assigned to the paraphyletic/polyphyletic family Kentriodontidae. Remains have been found in the middle Miocene ( Langhian) Calvert Formation of United States.
Harodelphis is similar to Macrokentriodon in its larger size and its large tooth diameter. [1] Despite being traditionally assigned to Kentriodontidae, recent cladistic analyses have recovered it along with Macrokentriodon in a clade with Kampholophos as sister to crown Delphinida and more derived than Kentriodon and Rudicetus. [2] [3]
Hadrodelphis poseidon was described from two isolated teeth from Miocene deposits in west-central France in 1971, but its validity was questioned by Dawson (1996). [4] [1]
