The protoconid and hypoconid are visible labially while the metaconid
is prominent lingually.
The entoconids are contiguous with hypoconids posteriorly and metaconids
NAP XV 162'08, a right m2 is quite worn lingually, missing the apex of the metaconid
, but preserving a strong, globose protoconid (Fig.
The anterolabial-anterolingual conulids are symmetrical, equal in size, and are of the same size as the metaconid
The m2 paraconid (MBLUZ-P-3.990; Table I; Figure 2f) is not anteriorly projected and lacks a meta-entoconid fold; metaconid
smaller than ml metaconid
and is covered by the lingual enamel band, which is going to the anterobuccal hypoconid edge; ento-hypoconid fold reflected 85[degrees] anteromesialy; hypoconid buccolingually broad, looks like a trigonid size; anterior facet of trigonid convex; lingual enamel band extends between metaconid
to anterolingual side of hypoconid, without covering it totally; buccal enamel fold deeper; buccal enamel band covering the anteromesial protoconid facet through posteromesial hypoconulid facet; hypoconid lingually projected; buccal enamel broader than lingual enamel.
In Ankylodon progressus and PTRM 1600, the protoconid and metaconid
have a direct buccal-lingual alignment as opposed to an oblique orientation in Ankylodon annectens.
Among all the conids the metaconid
is largest while entoconid is smallest.
The trigonid is formed by subequal protoconid and metaconid
with the protoconid slightly mesiad of the metaconid
The protoconid is slightly lower than the metaconid
. The molars are moderately rugose and bear weak stylids and ribs (Fig.
In particular, both have the main cusps arranged in opposite pairs, the tendency to a trilophodont M1 in adults, and an anteriorly-posteriorly compressed procingulum that coupled with its coalescence to the metaconid
produce on the m1 a nearly bilophodont pattern.
Symmetrical anteroconid, its labial lobe connects with the metaconid
. Welldeveloped labial cingulid, with a big round c1 and two or three accessory cuspids.
George (2012) was able to distinguish three autapomorphic characters for Notiosorex (diagnostic only to genus): (1) lightly pigmented teeth, (2) posterior extent of alveolus of i1 in labial view reaching past paraconid to metaconid
of m1, and (3) only one cusp, the hypoconid, present on talonid of m3.
