Keywords: Caribbean islands; Caviomorpha; Paleobiogeography; Paleogene; Rodentia

doi: 10.18563/journal.m3.127

  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 162447 View specimen

    M3#638_LACM 162447

    Right lower m3. This isolated 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.

    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.

Keywords: Africa; Djebelemuridae; Paleogene; Primates; Strepsirhini

doi: 10.18563/journal.m3.77

  Abstract

    This contribution contains the 3D models of the fossil remains (maxilla, dentary, and talus) attributed to Djebelemur martinezi, a ca. 50 Ma primate from Tunisia (Djebel Chambi), described and figured in the following publication: Marivaux et al. (2013), Djebelemur, a tiny pre-tooth-combed primate from the Eocene of Tunisia: a glimpse into the origin of crown strepsirhines. PLoS ONE. https://doi.org/10.1371/journal.pone.0080778

    - CBI-1-565, a damaged right mandible, which consists of three isolated pieces found together and reassembled here: the anterior part of the dentary bears the p3 and m1, and alveoli for p4, p2 and c, while the posterior part preserves m3 and a portion of the ascending ramus; the m2 was found isolated but in the same small calcareous block treated by acid processing. - CBI-1-577, isolated right lower p4. - CBI-1-587, isolated left lower p2 (reversed). - CBI-1-580, isolated left lower canine (reversed).
