“…Cenomanian through Campanian deep-marine sedimentation was followed by southward basin filling and shoaling upward to Maastrichtian shallow-marine and deltaic facies ( Figure 1) [Macellari et al, 1989;Fildani et al, 2008;Covault et al, 2009;Romans et al, 2011]. The Upper Cretaceous basin fill is unconformably overlain by shallow-marine and continental Paleocene through Miocene strata ( Figure 1) [Biddle et al, 1986;Malumián et al, 2000;Otero et al, 2012;Bostelmann et al, 2013].…”

“…In some parts of the SBMR the glacial cirques are developed over sedimentary rocks of the Eocene Man Aike Formation, a sequence of shales, sandstones and conglomerates with numerous mollusk fossils that overlies the Cretaceous Dorotea Formation and is, in turn, overlain by continental shales and sandstones rich in plant fossils belonging to the Río Leona Formation. The latter is followed by sandstones, conglomerates and mudstones of the Estancia 25 de Mayo and Santa Cruz Formations (Le Roux et al, 2010;Bostelmann et al, 2013). Gutiérrez et al (2013) mentioned that the Estancia 25 de Mayo Formation is intruded by laccolith-type plutons and olivine-gabbro sills.…”

“…y el puma (Puma concolor), además de una variedad de aves, mustélidos y roedores (Muñoz-Pedreros y Yáñez, 2000). En cuanto a sus características geomorfológicas, sierra Baguales destaca por presentar una de las más completas e ininterrumpidas secuencias sedimentarias Mesozoicas-Cenozoicas de la cuenca austral de Sudamérica (Gutiérrez et al, 2013), las cuales incluyen a las formaciones Las Flores (Man Aike), La Cumbre, Río Leona, Estancia 25 de Mayo y Santa Cruz (Bostelmann et al, 2013). La emergencia de estas formaciones generó la disponibilidad de diversas materias primas líticas, facilitando así que grupos cazadores-recolectores obtuvieran rodados y bloques de diferente tipo y calidad, tanto en sectores altos de la sierra como en sus alrededores.…”
