This contribution contains the three-dimensional digital models of fossil remains of platyrrhine primates from the late Middle to early Late Miocene (Upper Solimões Formation) of the State of Acre, Brazil (Western Amazonia). These fossils were described, figured and discussed in the following publication: Marivaux et al. (2026), New records of platyrrhine primates (Atelidae and Cebidae) from the Miocene of Western Amazonia, State of Acre, Brazil.

This contribution contains the three-dimensional digital model of one isolated fossil tooth of an anthropoid primate (Ashaninkacebus simpsoni), discovered in sedimentary deposits located on the upper Rio Juruá in State of Acre, Brazil (Western Amazonia). This fossil was described, figured and discussed in the following publication: Marivaux et al. (2023), An eosimiid primate of South Asian affinities in the Paleogene of Western Amazonia and the origin of New World monkeys.
