A Late Eocene age proposal for the Loreto Formation (Brunswick Peninsula, southernmost Chile), based on fossil cartilaginous fishes, paleobotany and radiometric evidence

Abstract

ABsTRACT. We present new data on the paleoichthyology, paleobotany and radiometric results of the Loreto Formation in the Brunswick

Depósitos burdigalianos de la Formación Santa Cruz en Sierra Baguales, Cuenca Austral (Magallanes): Edad, ambiente de deposición y vertebrados fósiles.

“…At the same time, our field work has encompassed much of the Cenozoic succession in the northern half of the region, along with dramatically increasing our knowledge on the paleontological diversity of this part of the country (Torres et al, 2009;Le Roux et al, 2010;Sallaberry et al, 2010;Otero et al, 2012a;Otero et al, 2012b, in press).…”

Palinomorfos continentales del Paleógeno de las formaciones Chorrillo Chico y Agua Fresca, Punta Prat, Región de Magallanes, Chile

“…Esta unidad está compuesta principalmente por lutitas, areniscas glauconíticas con concreciones y delgadas capas de caliza (Otero et al, 2012). Los foraminíferos reportados de esta formación indican una edad paleocena sin diferenciar (Martínez-Pardo, 1971).…”

A preliminary report on the Early Oligocene (Rupelian, Kiscellian) selachians from the Kiscell Formation (Buda Mts, Hungary), with the re-discovery of Wilhelm Weiler’s shark teeth

“…C. catticus is thought to be a neritic, medium sized form. Th e species has been reported from Western Africa and Europe, from the middle Oligocene to the middle Miocene (Cappetta 1987), however, exceptional Eocene reports are also known (Otero et al 2012(Otero et al , 2013.…”
