On the hypoconid, this crest forms a right angle with the posterolophid, which runs towards the hypoconulid in the back lingual corner of the tooth.
12.
They are named after their locations, e . g . a paraconule is located between a paracone and a metacone, a hypoconulid is located between a hypoconid and an entoconid.
13.
There is a well-developed cingulid at the outer back margin ( distobuccally ), between the hypoconid ( one of the main cusps ) and the hypoconulid ( a smaller cuspule ).
14.
No other cusps are visible in the talonid, but the specimen is worn and poorly preserved; the posterolophid, a crest descending from the hypoconid, may end in a small hypoconulid.
15.
The distinguishing features of " Pelycodus " from " Cantius " are its anteroposteriorly compressed trigonid, its small paraconid on M 2 and lack of hypoconulid on M 1-2.
16.
The smaller hypoconulid cusp is present towards the inner side of the tooth, and the hypoconid and hypoconulid are connected by a cutting edge which is suggestive of the presence of a metacone cusp on the upper molars.

18.
In " D . chimaera ", a low crest, the post-hypoconulid cristid, reaches from the hypoconulid to the back lingual corner of the tooth, where a small cuspule, the distocuspid, is located.

20.
The last lower molar, m3, is smaller and has a longer talonid, with a well-developed hypoconulid lobe at the back, and generally resembles that of " Phenacopithecus ", but the trigonid is smaller.
