Eudelphis mortezelensis

Mammalia - Artiodactyla

Taxonomy
Eudelphis mortezelensis was named by Du Bus (1872). Its type specimen is IRSNB M.523, a partial skull (partial skull with two teeth), and it is a 3D body fossil. Its type locality is Vieux-Dieu, which is in a Langhian/Serravallian open shallow subtidal sandstone in the Berchem Formation of Belgium.

It was recombined as Delphinus mortezelensis by du Bus (1872), Trouessart (1898) and Trouessart (1904); it was recombined as Scaldicetus mortezelensis by Kazár (2002) and Hampe (2006).

Diagnosis
ReferenceDiagnosis
O. Lambert 2008Eudelphis mortezelensis is a moderate size physeteroid somewhat larger than Orycterocetus crocodilinus. It differs from all the other members of the superfamily in: the presence of a large left premaxillary foramen, the vomer widely exposed in ventral view, and the postglenoid process of the squamosal ventrally elongated. It differs from all the other physeteroids except Zygophyseter in the plate-like falciform process of the squamosal, from all the other physeteroids except Scaphokogia in the rostrum more progressively narrowing forwards, from Brygmophyseter and Zygophyseter in the proportionally smaller teeth, from Zygophyseter in the shorter zygomatic process of the squamosal, from Idiorophus and Scaphokogia in the widely dorsally open mesorostral groove, from Aulophyseter, Idiophyseter, Kogia, Orycterocetus, Physeter, and Scaphokogia in the presence of at least 10 deep maxillary alveoli, from Aulophyseter, Kogia, Orycterocetus, Physeter, and Physeterula in the enamelled crown of the teeth, and from Aulophyseter, Orycterocetus, Physeter, and Physeterula in the low supraoccipital shield.
