Allodelphinidae

Mammalia - Ungulata - Allodelphinidae

Taxonomy
Allodelphinidae was named by Barnes (2006) [A family of the odontocete superfamily Platanistoidea having cranium with elongate and narrow rostrum; rostrallength more than four times braincase length; premaxillae and maxillae both reaching anterior rostral extremity; premaxillae and maxillae fused together distally; mesorostral groove open dorsally on at least posterior part of rostrum; anteroposteriorly elongated groove present on lateral side of rostrum approximately following maxilla/premaxilla suture; facial region around dorsal narial opening and cranial vertex elevated in sagittal plane and sloping laterally onto supraorbital processes; posterior maxillary foramen located posterolateral to external naris and not close to posterior end of premaxilla; posterolateral sulcus on premaxilla shallow and not enlarged; posterior end of premaxilla irregularly-shaped, thin dorsoventrally, and narrow (not expanded transversely); nasals elongate anteroposteriorly and narrow transversely; nuchal crest thickened anteroposteriorly and elevated; lateral lamina of pterygoid present (formed as an outer lamina or bony plate of pterygoid within orbit), extending posteriorly from palate and contacting styliform process of squamosal; zygomatic process of squamosal not expanded dorsoventrally, not compressed transversely, and glenoid fossa facing anteroventrally; no fossa for posterior sinus present within anterior surface of paroccipital process; tympanic bulla with elongated and pointed anterior spine, with thin outer lip that is smoothly over-arching and high relative to transverse width of bulla; mandible with symphyseal portion narrow, anteroposteriorly elongated, and dorsoventrally compressed; mandibular symphysis firmly ankylosed; all teeth single-rooted; cervical vertebrae large and with anteroposteriorly elongated centra; atlas vertebra bearing both dorsal and ventral transverse processes; thoracic vertebrae not greatly enlarged; lumbar vertebrae large and with anteroposteriorly elongate centra; caudal vertebrae enlarged; humerus with diaphysis proximo-distally elongate and oval in cross section; humeral head large and ovoid-shaped; propensity for humerus to non-pathologically fuse to ulna.].

It was assigned to Platanistoidea by Barnes (2006), Barnes and Reynolds (2009), Aguirre-Fernández and Fordyce (2014), Boersma and Pyenson (2016), Marx et al. (2016), Kimura and Barnes (2016) and Berta (2017).

If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
