M1 subtriangular, with well-developed metaconule
united to the protocone, lingual part with a tendency to reduction.
is present posterior to the protocone.
There is no clear cut demarcation between the metaconule
and the protocone.
1 (basalmost artiodactyls [paraphyletic]: diacodexid, primitive [unassigned, some dichobunine] dichobunid dichobunoids): Ml-3 (Ms) bunodont, triangular; metaconule
unenlarged; no hypocone (Old World [OW] origin).
The lack of the paraconule and metaconule
suggest a primitive morphology and support the assignment to the Hesperocyoninae.
is pyramidal in shape with a moderately developed preme tacrista that is mesiolingually directed to join the slight lingual cingulum between protocone and metaconule
The metacone is partially broken, and connected to the metaconule
by a narrow crest.
The tooth can be described as follows: ectoloph is typically W-shaped; hypocone is absent but a postprotocrista extends posteriad from the metaconule
as a curved sloping ridge with a small talon formed by its base.
2] from Casa Ramon shows poorly-developed metaconule
crests, and small paraconule and metaconule
Protoloph and metaloph present protoconule and metaconule
Morphologically, the scarce material from CA2 is characterized by the presence of a connection between metaconule
and protocone in D4 and P4.
Four main cusps: protocone, paracone, metacone and hypocone and three conules: anteroconule, metaconule
