First record of Scelidodon chiliense (Lydekker)(Phyllophaga, Scelidotheriinae) from the Lujanian Stage (Late Pleistocene - Early Holocene) of Argentina


Miño-Boilini, Á R; Carlini, A A; Chiesa, J O; Lucero, N P; Zurita, A E (2009). First record of Scelidodon chiliense (Lydekker)(Phyllophaga, Scelidotheriinae) from the Lujanian Stage (Late Pleistocene - Early Holocene) of Argentina. Neues Jahrbuch für Geologie und Paläontologie, 253(2-3):373-381.

Abstract

The Scelidotheriinae constitutes a group of sloth with numerous problematics, mainly related to their origin and phylogenetic relationships. This subfamily is principally characterized by a narrow and elongated skull, a coincident modification of the dental series and having a medium size. It is reported the first record of Scelidodon chiliense (Lydekker) (Phyllophaga, Scelidotheriinae), exhumed from Lujanian sediments (Late Pleistocene - Early Holocene) belonging to the Uspara Formation of San Luis Province (Argentina). The fossil (MHIN-UNSL GEO V-199) consists of a sub-complete skull without teeth, except the right M1. The specific assignation is mainly based on: sagittal and temporal crests with little development and parietal and squamosal bones separated by an horizontal suture. This reports broad the geographical distribution of the species, known so far only for northern Chile, Bolivia, Peru and Ecuador. Finally, it allows raising and discussing some hypothesis related to its presence into the current territory of Argentina.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
