Diagnosis
ReferenceDiagnosis
M. D. Uhen et al. 2008Xiphiacetus differs from Schizodelphis in: more robust skull with more progressiveelevation of the premaxillae towares the vertex; medial plate of the maxilla along the vertex less concave and less erected; thicker supraorbital process; rostrum generally relatively wider at its base. It differs from Ziphiodelphis in: narrower and ticker triangular part of the premaxilla medially to premaxillary foramen, lacking the more regular flatness and lateral slope seen in Ziphiodelphis; mesorostral groove widely open at that level; posterolaterally shorter plate of the maxilla along the vertex giving the posterodorsal outline of the skull a more rounded aspect in lateral view. It differs from Eurhinodelphis in: maxillary part of the rostrum relatively shorter; dorsomedian portion of the supraoccipital shield concave; less elevated and wider paroccipital process of the exoccipital with lower occipital condyles. It differs from Argyrocetus in: relatively wider face; more elevated vertex ith nasal longer than wide, at the same level or lower than the frontal; more erected supraoccipital shield. It differs from Macrodelphinus in: more elevated and more transversly compressed vertex withnasal as long as wide or longer than wide, and forntal as long as, or shorter than the nasal: supraoccipital shield closer to the vertical. It differs from Mycteriacetus in: relatively wider cranium; more elevated vertex with nasal at the same level or lower than the frontal, and frontal as long as, or shorter than the nasal; more erected supraoccipital shield (Lamert, 2005b).
