In " Indraloris himalayensis " lower molars, there are four main cusps ( protoconid and metaconid in the trigonid, hypoconid and entoconid in the talonid ), which give the crown a rectangular aspect, although the labial cusps ( protoconid and hypoconid ) are placed somewhat anterior to their lingual counterparts.

The front half of the m1 and m2 consists of the trigonid, a group of three cusps forming a triangle : the paraconid at the front on the inner side, protoconid in the middle on the outer ( labial ) side, and metaconid at the back on the inner side ( see Figure 2 ).

The P 4 of " Attockicetus " is similar to those of " Pakicetus " in retaining a tall protoconid ( cusp ) and anterior and posterior basal extensions with prominent cristae ( crests ), but differs from them in having steeper protoconid slopes, being taller, and having longer basal extensions.

Muirhead ( 1997 p . 372 ) describes " W . ridei " as having the following features that are unique : parametacrista on the first molar is straight, entoconid either missing of combined with the hypoconid in a more posterior position, the loss or reduction of styler crests, small metaconid, talonid basin reduced by the Ngamalacinus ", and that is the metaconid and protoconid are reduced.

A bat humerus ( upper arm bone ) from the same site could not be identified as either " T . goodmani " or the living " molars . " T . goodmani " is larger than the living species of " Triaenops " and " Paratriaenops " on Madagascar, and on the first molar the protoconid cusp is only slightly higher than the hypoconid, not much higher as in the other species.

Some of these features include " small size, generally simple dental structure, less enamel plication and crenulation and thus the valleys of the premolars are well separated, slender teeth, bicuspid mesial lophid in P3 ( the cuspids are distinct but more compressed against each other than in P . hobleyi ), and clear mesial projection ( preprotolophide ) in P3; sometimes is bicuspid . " Other features noted earlier in 1957 include " the mesial lophid of P3 is well separated into two cuspids, the mesial projection of P3 is well developed and often bicuspid, and the base of the protoconid in P3 is longer than that of the metaconid . " " P . hobleyi " differs in morphology from " P . bavaricum " mostly in these P3 characteristics.
