Dasychoerus sp. from Kvabebi

Propotamochoerus provincialis race minor – Mottl 1939: 324, pl. 4, fig. 4, pl. 5, fig. 1.

MATERIAL. — FSL 40 152, right M3/ ( Fig. 11A ).

REMARK

Differential diagnosis. is un-named suid species is intermediate in dimensions between “ Sus ” provincialis and Dasychoerus arvernensis . Talon in upper third molar centrally positioned.

DESCRIPTION

An isolated upper third molar from Montpellier stands out from the rest of the specimens from the deposits by its dimensions and talon morphology, the tooth resembling specimens from Kvabebi, Georgia ( Vekua 1972) (see Figs 5 ; 11A ; 16 ). FSL 40 152, is lightly worn and has a symmetrical crown outline and a simple talon ( Fig. 11A ). e lingual cusps in each cusp pair are slightly behind the level of the buccal cusps. e mesial cingulum is mesio-distally broad the main cusps show marked lingual and buccal flare and the talon is slightly enlarged and centrally positioned directly behind the posterior accessory cusplet (hypoconule). e anterior, median and posterior accessory cusplets are mesio-distally compressed. e Fürchen are subdued indicating that the enamel is thick. ere are basal pillars at the ends of the median and posterior transverse valleys.

FIG. 16. — Bivariate plot of upper and lower third molars of suids from Montpellier (white M) and other Late Miocene and Plio-Pleistocene localities in Europe. The sloping black line separates the upper molars from the lower ones. There are four size groups of suids at Montpellier corresponding in dimensions to Dasychoerus arvernensis for the smallest group, Dasychoerus sp. from Kvabebi for an intermediate sized group, “Sus” provincialis for a slightly larger medium sized group, and Dasychoerus strozzii for the largest one.
