  Abstract

    This contribution contains the 3D models of the fossil teeth of two chinchilloid caviomorph rodents (Borikenomys praecursor and Chinchilloidea gen. et sp. indet.) discovered from lower Oligocene deposits of Puerto Rico, San Sebastian Formation (locality LACM Loc. 8060). These fossils were described and figured in the following publication: Marivaux et al. (2020), Early Oligocene chinchilloid caviomorphs from Puerto Rico and the initial rodent colonization of the West Indies. Proceedings of the Royal Society B. http://dx.doi.org/10.1098/rspb.2019.2806

    Borikenomys praecursor LACM 162446 View specimen

    M3#639_LACM 162446

    Fragment of lower molar (most of the mesial part). This isolated broken tooth was scanned with a resolution of 6 µm using a μ-CT-scanning station EasyTom 150 / Rx Solutions (Montpellier RIO Imaging, ISE-M, Montpellier, France). AVIZO 7.1 (Visualization Sciences Group) software was used for visualization, segmentation, and 3D rendering. The specimen was prepared within a “labelfield” module of AVIZO, using the segmentation threshold selection tool.

    M3#640_LACM 162448

    Fragment of either an upper tooth (mesial laminae) or a lower tooth (distal laminae). The specimen was scanned with a resolution of 6 µm using a μ-CT-scanning station EasyTom 150 / Rx Solutions (Montpellier RIO Imaging, ISE-M, Montpellier, France). AVIZO 7.1 (Visualization Sciences Group) software was used for visualization, segmentation, and 3D rendering. This fragment of tooth was prepared within a “labelfield” module of AVIZO, using the segmentation threshold selection tool.

  Abstract

    This contribution contains the 3D models of the fossil teeth of a small-bodied platyrrhine primate, Neosaimiri cf. fieldsi (Cebinae, Cebidae, Platyrrhini) discovered from Laventan deposits (late Middle Miocene) of Peruvian Amazonia, San Martín Department (TAR-31: Tarapoto/Juan Guerra vertebrate fossil-bearing locus n°31). These fossils were described and figured in the following publication: Marivaux et al. (2020), New record of Neosaimiri (Cebidae, Platyrrhini) from the late Middle Miocene of Peruvian Amazonia. Journal of Human Evolution. https://doi.org/10.1016/j.jhevol.2020.102835
