| The Honda Group exposed in La Venta consists of three formations: the Cervatana, Villavieja and Las Mesitas Formations (in ascending order). Most of the primate and other mammalian fossils have been obtained from the Villavieja Formation, which consists of alternating beds of claystone, silt stone and sandstone. The Villavieja Formation is subdivided into four members: the Molina, Los Mangos Red, Las Lajas and Tatacoa Red Members (in ascending order). The “Monkey Unit” of Fields (1959), which is very famous for yielding many primate fossils, corresponds to the lower part of the Molina Member. The present materials were recovered from the Masato Site, which corresponds to the lowest part of the Tatacoa Red Member. | ||||

| Boivin et al. (2021): These levels were originally mapped as belonging to the lower member of Ipururo Formation (middle Miocene in age in the Huallaga basin) [Antoine et al. 2021], an assignation in agreement with the nature of their facies and depositional environment sequence. The fossil content of the TAR-31 encompasses plants, amber clasts, crabs, chondrichthyans, osteichthyans, anurans, chelonians, crocodylomorphs, birds, and mammals (including metatherians, xenarthrans, liptoterns, notungulates, sirenians, chiropterans, primates, and caviomorph rodents). The TAR-31 mammal assemblage includes a didelphid marsupial (currently under study by one of us, NSS), the interatheriine notoungulate Miocochilius sp., the didolodontid Megadolodus sp., the platyrrhine primate Neosaimiri aff. fieldsi [Marivaux et al. 2020], and the caviomorph fauna described here (see ‘Age of TAR-31’ section of this present work). This assemblage recalls some of the Laventan SALMA localities: Quebrada Honda in Bolivia (13.112.2 Ma) [Gibert et al. 2020], the Fitzcarrald local fauna in SE Peru [Tejada-Lara et al. 2015], and especially the lower part of the Villavieja Formation in the La Venta area in Colombia (13.8–11.6 Ma; [Flynn et al. 1007] and see above). Accordingly, the TAR-31 locality most likely documents the late middle Miocene Laventan SALMA [Marivaux et al. 2020]. | Boivin et al. (2021): TAR-31 consists of a 10–15 cm-thick yellow microconglomerate interbedded within a grey cross-stratified and sandstone-dominated fluvial unit (Fig 2A [Marivaux et al. 2020]). The latter is intercalated between thick violin-grey variegated paleosols pointing to the existence of a meandering river with a sustainable floodplain [Marivaux et al. 2020]. | Boivin et al. (2021): The primary purpose of the present work is to describe the new caviomorph materials found in TAR-31. The caviomorph material corresponds to about 400 isolated teeth (complete or fragmentary), one fragment of mandible (MUSM 4643), one fragment of maxilla (MUSM 4375), and one astragalus (MUSM 4658). No permits were required for the described study, which complied with all relevant regulations. The field work on TAR-31 was carried out in the framework of the ongoing cooperation agreement between the ‘Museo de Historia Natural de la Universidad Nacional Mayor San Marcos’ (Lima, Peru) and the ‘Institut des Sciences de l’Evolution de Montpellier-Universite ́ de Montpellier’ (France). The TAR-31 fossil specimens are permanently stored in the palaeontological collection of the ‘Museo de Historia Natural, Universidad Nacional Mayor de San Marcos’, Lima, Peru (MUSM). |
