Análisis Icnológico y Paleoambiental de la Aloformación Punta San Andrés (Plio-Pleistoceno), Provincia de Buenos Aires, Argentina

Mammalian predator–prey relationships and reoccupation of burrows in the Pliocene of the Pampean Region (Argentina): new ichnological and taphonomic evidence

“…Type 2 (35-70 cm): This size type has scarce records (Beilinson and Taglioretti, 2013) and it has not been linked to any specific fossorial mammals group.…”

“…More recent contributions have deepened our knowledge of their taphonomic, structural and sedimentary aspects, as well as those related to the palaeobiology of builder organisms (Imbellone and Terruggi 1988;Genise 1989;Zárate 1989;Imbellone et al 1990;Scognamillo 1993;Bergqvist and Maciel 1994;Peña 1997;Zárate et al 1998;Bargo et al 2000;Fernández et al 2000;Isla and Dondas 2001;Vizcaíno et al 2001Tassara et al 2005;De los Reyes et al 2006;Soibelzon et al 2009;Dondas et al 2009;Buchmann et al 2009;Elissamburu et al 2011;Frank et al 2012Frank et al , 2013Beilinson and Taglioretti 2013).…”

Microvertebrates preserved in mammal burrows from the Holocene of the Argentine Pampas: a taphonomic and paleoecological approach

“…The presence of remains inside burrows has been highlighted by numerous authors for the late Miocenelate Holocene of the Argentine Pampas (e.g. Genise 1989;Scognamillo 1993;Peña 1997;Elissamburu et al 2011;Beilinson and Taglioretti 2013;Tomassini and Montalvo 2013;Cenizo et al 2015). However, the origin of small vertebrates assemblages is barely studied taphonomically (e.g.…”

Coprinisphaera akatanka isp. nov.: The first fossil brood ball attributable to necrophagous dung beetles associated with an Early Pleistocene environmental stress in the Pampean region (Argentina)

“…The lower section was correlated to the Ensenada Formation by Bidegain et al (2005), and could be also attributed to the San Andrés Formation (Kraglievich, 1952). Comparable deposits identified in exposures along Mar del Plata, Chapadmalal, Miramar, and Centinela del Mar coastal cliffs were grouped in the Punta San Andrés Alloformation (Zárate, 1989;Beilinson, 2009;Cenizo, 2011). At the type locality, the latter is composed by siltstones and silty claystones of aeolian (loessic) and subordinately fluvial origin, intensely modified by pedogenesis (Kraglievich, 1952;Zárate and Fasano, 1984).…”
