This tooth displays a very peculiar occlusal morphology, which enables it to be distinguished from all other pliopithecids for which this dental posi tion is known (including Barberapithecus, see below, but not Pliopithecus canmatensis).
The pliopithecine morphology and the small size of the dental remains from these several localities from Abocador de Can Mata is most similar to that of Pliopithecus antiquus from the French localities of Sansan (MN6) and La Grive (MN7+8), but dental proportions as well as several occlusal details (less peripheral position of the protoconid and more median position of the hypoconulid, more mesial position of the buccal cuspids compared to the lingual ones, narrower but distinct mesial fovea, higher trigonid, and more extensive buccal cingulid) justify a taxonomic distinction at the species level for the ACM material (Alba et al, 2010d).
Both in size and morphology, this tooth is consistent with an attribution to Pliopithecus platyodon, otherwise unknown from the Iberian Peninsula.
They were partly described and initially attributed to Pliopithecus sp.
This material was initially published by Golpe-Posse (1982b), who attributed it to Pliopithecus sp.
The best known pliopithecine from Iberia is Pliopithecus canmatensis, from the late Middle Miocene of several localities from the Abocador de Can Mata series (Alba et al.
canmatensis, after the site (Can Mata in the Valles-Penedes basin), the primate belonged to an extinct family of Old World monkeys, Catarrhini, which dispersed from Africa to Eurasia.
