 | | To resolve delphinidan phylogeny, we gathered new morphological and molecular data and concatenated it with published data sets to create a matrix of 65 taxa (of which 40 are extinct) scored for 328 morphological characters, 25 transposon characters, and 945 informative nucleotide characters distributed across 7.4 kilobases. |
 | | As in several previous studies, we found a monophyletic Delphinoidea, a sister-group relationship between Monodontidae and Phocoenidae, and Inia and Pontoporia to be sister-groups. |
 | | The extinct delphinidan Parapontoporia grouped with the Yangtze River dolphin, Lipotes, to form Lipotidae, which we found to be the most basal delphinidan clade. |
