The tooth is slightly damaged at the posterior side, hence the metacone is not well differentiated.

The paracone and metacone are sharp with their cristae running antero-posteriorly namely praeparacrista, postparacrista, praemetacrista and postmetacrista respectively.

3 (most-derived dichobunoids [dichobunine Dichobune, hyperdichobunine dichobunids; might include other dichobunids with quadrate hypoconiferous Ms] plus caenotheriids); Ms relatively selenodont, quadrate; tritubercular distal lobe with distinct metacone, metaconule, and hypocone; TV continuous; paraconule reduced/lost (OW).
Early evolution, diversification, and geographic distribution of the suborders constituting the mammalian order artiodactyla

For Phyllostomini, these include the anterior mesostyle and metastyle of [M.sup.1-2] ([ILLUSTRATION FOR FIGURE 1A OMITTED], points 5-8); for Stenodermatini and Glossophagini, points were taken on the presumed paracone and metacone of [M.sup.1] and paracone of [M.sup.2] ([ILLUSTRATION FOR FIGURE 1B, C OMITTED], points 6-8).
Application of fitted polynomial functions to modeling contours derived from mammalian mandibular and dental morphology
The presence of rudimentary entostyles in some molars, the prominence of paracone rib as compared to the metacone rib and the open p4 anterior valley as opposed to the partially closed posterior one, are the characters that strongly suggest their inclusion to an extinct Siwalik species G.
Fossil Bovidae from Late Miocene Dhok Pathan Formation of Siwaliks, Northern Pakistan
To determine cusp relief, we measured the depth of the valley between the paracone and metacone cusps as well as the anteroposterior length of each tooth using the computer software ImageJ 1.47 (Rasband, 2013).
