    • Freshwater turtles (Testudines: Pleurodira) in the Upper Cretaceous of Chilean Patagonia 
      Alarcón Muñoz, Jhonatan; Soto Acuña, Sergio; Manríquez, Leslie M. E.; Fernández, Roy A.; Bajor, Dániel; Guevara, Juan Pablo; Suazo Lara, Felipe; Leppe, Marcelo A.; Vargas Milne, Alexander (Elsevier, 2020)
      We describe remains of freshwater turtles from the Upper Cretaceous of Chilean Patagonia. The fossils, which comprise isolated shell fragments and incomplete appendicular bones, were recovered from meandering fluvial ...
    • Largest baleen whale mass mortality during strong El Niño event is likely related to harmful toxic algal bloom 
      Haussermann, Verena; Simon Gutstein, Carolina; Bedington, Michael; Cassis, David; Olavarría, Carlos; Dale, Andrew C.; Valenzuela Toro, Ana M.; Pérez Álvarez, María José; Sepúlveda, Héctor H.; McConnell, Kaitlin M.; Horwitz, Fanny E.; Försterra, Günter (PeerJ, 2017-05-31)
      While large mass mortality events (MMEs) are well known for toothed whales, they have been rare in baleen whales due to their less gregarious behavior. Although in most cases the cause of mortality has not been conclusively ...
    • Late Jurassic Sauropods In Chilean Patagonia 
      Salgado, Leonardo; Novas, Fernando E.; Suárez, Manuel; Cruz, Rita de la; Isasi, Marcelo; Rubilar Rogers, David; Vargas, Alexander O. (Asociacion Paleontologica Argentina, 2015)
      A description is provided of the first sauropod remains (i.e., isolated vertebrae and appendicular bones) from the Late Jurassic of Aysen, in Chilean Patagonia (Toqui Formation, late Tithonian). Although the bones found ...
    • Provenance of northwestern Patagonian river sediments (44-48 degrees S): A critical evaluation of mineralogical, ... 
      Liu, Dawei; Bertrand, Sebastien; Villaseñor, Tania; Van Dijck, Toon; Fagel, Nathalie; Mattielli, Nadine (Elsevier, 2020)
      The ability to trace and quantify sediment provenance in northwestern Patagonia is increasingly needed to properly understand modem sediment erosion and transport processes in this rapidly changing environment, and to ...
    • Recent glacier variations on Mount Melimoyu (44 degrees 50'S-72 degrees 51'W), Chilean Patagonia, using ... 
      Idalino, Filipe Daros; da Rosa, Katia Kellem; Ferrando Acuña, Francisco; Veettil, Bijeesh Kozhikkodan; Cardia Simões, Jefferson; Souza, Enoil (Taylor & Francis, 2020)
      This work analyzed the application of Sentinel-2 multispectral imagery and GLIMS data for mapping glacier retreat and to estimate glacier area changes of Mount Melimoyu, located in northern Patagonia, Chile for the period ...
    • Slab-derived components in the subcontinental lithospheric mantle beneath Chilean Patagonia: Geochemistry ... 
      Jalowitzki, Tiago; Gervasoni, Fernanda; Conceição, Rommulo V.; Orihashi, Yuji; Bertotto, Gustavo W.; Sumino, Hirochika; Schilling, Manuel E.; Nagao, Keisuke; Morata Céspedes, Diego; Sylvester, Paul (Elsevier, 2017)
      In subduction zones, ultramafic xenoliths hosted in alkaline basalts can yield significant information about the role of potential slab-derived components in the subcontinental lithospheric mantle (SCLM). Chemical ...
