was probably absent, although the state of preservation of the tooth does not permit a firm conclusion to be reached, although close inspection reveals that the trigonid valley was very small, tall and closed anteriorly.
The partial lower jaw also appears to have the alveolus of i1 extending posteriorly beneath the paraconid
of m1, a distinguishing feature of the genus Notiosorex (Carraway and Timm, 2000).
is supported by a thin parastylid anterolingually.
of the P4 is strongly developed and rather larger than the parastylid.
geismarianus is characterized by an m I with a low, short trigonid with the metaconid slightly more posterior than the protoconid, a large talonid, subequal entoconid and hypoconid, compressed m2 trigonid with an anterobuccal cingulid, and a very small paraconid
SDSM 8640 differs from N geismarianus in that the length of the ml is not as reduced and has a lesser degree of trigonid compression on the m2.
Protoconid is slightly longer anteroposteriorly and higher than the paraconid
aratathomasi, no cusp is apparent in the position designated by Miller (1907) as the paraconid
on m1 in S.
Isolated lower teeth: The paraconid
is separated from the parastylid in the premolars (Fig.
lusitanica differ from those of the other species of the genus in the smaller paraconid
and a shorter trigonid when compared to the talonid.
The primary cusp is about the same height as the paraconid
In the p3 a strong protoconid linked by a straight longitudinal crest to a small mesio-lingually situated paraconid
and protoconid occupies two-thirds of the premolar length (Fig.
