- Paleogene Glyptodontidae Propalaehoplophorinae (Mammalia, Xenarthra) in extra-Patagonian areas Alfredo E. Zurita Laureano R. González-Ruiz Angel R. Miño-Boilini Rafael Herbst Gustavo J. Scillato-Yané Pedro Cuaranta Ciencias de la Tierra Oligocene Osteoderms Glyptodonts Mesopotamian Region Fray Bentos Formation Paleogene records of Cingulata Glyptodontidae are scarce. The only well described comes from the Paleogene of Argentine Patagonia. Two subfamilies have been reported for that period: Glyptatelinae and Propalaehoplophorinae. Until this contribution, the latter taxon was geographically restricted to the locality of El Pajarito (Late Oligocene, Deseadan SALMA), Chubut province, Argentina. Here we present and describe the northernmost record of a Paleogene Propalaehoplophorinae. The material is represented by three associated osteoderms of the dorsal carapace from the Fray Bentos Formation (Late Oligocene, Deseadan SALMA) in the locality of Cueva del Tigre, Chajarí, Entre Ríos province, Argentina. Morphologically, these remains are almost identical to those reported from the late Oligocene of the Patagonian region, showing that during the Paleogene the Propalaehoplophorinae had a larger latitudinal distribution than previously known. 2016 artículo científico 0718-7092 https://www.redalyc.org/articulo.oa?id=173943660007 https://www.redalyc.org/journal/1739/173943660007/ https://www.redalyc.org/journal/1739/173943660007/html/ https://www.redalyc.org/journal/1739/173943660007/173943660007.epub https://www.redalyc.org/journal/1739/173943660007/movil en http://www.redalyc.org/revista.oa?id=1739 Andean Geology application/pdf Servicio Nacional de Geología y Minería Andean Geology (Chile) Num.1 Vol.43
