Hippopotamodon sivalense
LYDE-
KKER, 1877
Diagnosis. Large
Suinae
in which the males have flaring canines (smaller in Turolian species); molar enamel relatively thin; molars structurally simple with well-developed Fürchenplan; buccal cusps in lower molars noticeably lower crowned than lingual ones; P4/ with posterior accessory cusp almost as large as two main buccal cusps; sagittal cusplets present in central valley between the protocone and the paracone-metacone; p/1 often absent in some Turolian populations; posterior choanae U-shaped, open immediately behind M3/; p/4 with prominent innenhugel and 2-3-4 cusp, anterior cingulum and ac-1 cusp moderately high; diastema between c/1–p/1–p/2 short; broad flat dorsal surface to braincase; the maxillae of males possess a large supracanine flange with a highly rugose dorsal surface, females do not have such a flange (modified from

Note.
Pickford (
1988
)
retained two genera for the large Late Miocene suines,
Hippopotamodon
and
Microstonyx
. Whilst there are some morphological differences between the various species included in these “genera”, they are relatively minor, concerning principally the canine, which is rare or absent in many collections. Perusal of the literature reveals that the decision to identify a fossil as
Hippopotamodon
or
Microstonyx
has often boiled down to where it came from (Indo-Pakistan for
Hippopotamodon
; Europe for
Microstonyx
), rather than on morphological evidence. For this reason, in this paper
Hippopotamodon
is employed for these suids, regardless of their provenience. Part of the reason for doing this is that adoption of two genus names gives the impression that there are important biogeographic differences between Europe and Indo-Pakistan during the Vallesian and Turolian, which is probably not the case.
