They differ from " Sivaladapis " teeth in being shorter and broader, with a shorter talonid and a smaller hypoconulid.
12.
The second molar ( m2 ) is similar and only a trifle smaller, but m3 is much smaller and has a reduced talonid.
13.
The p4 and molars have a distinct trigonid ( a triangular group of cusps at the front of a tribosphenic tooth ) and talonid.
14.
The p4, represented by YGSP 24338, is an elongate, two-rooted tooth with a distinct trigonid at the front and talonid at the back.
15.
Characters placing it in " Phlaocyon " includes robust and shortened premolars, a quadrate first upper molar, and widened talonid on the first lower molar.
16.
The trigonid and talonid are about as broad, the trigonid is low-crowned, and wear is mainly horizontal, resulting in broad, flat exposed wear facets.
17.
It is wider than long and contains a well-developed cusp, the hypoconid, on the outer side and a depression, the talonid basin, in the middle.
18.
They proposed that wear in the australosphenidan talonid occurs mainly on the rims, not in the talonid basin itself, and that australosphenidans may not have had a functional protocone.
19.
They proposed that wear in the australosphenidan talonid occurs mainly on the rims, not in the talonid basin itself, and that australosphenidans may not have had a functional protocone.
20.
Some Jurassic mammals, such as " Shuotherium " and " Pseudotribos ", have " reversed tribosphenic " molars, in which the talonid is towards the front.
