Fossil mesofauna and bacteria recovered from a paleosol in a moraine situated adjacent to the inland ice, Antarctica, and dating to the earliest glacial event in the Antarctic Dry Valleys opens several questions. The most important relates to understanding of the mineralogy and chemistry of the weathered substrate habitat in which Coleoptera apparently thrived at some point in the Early/Middle Miocene...
Middle-Miocene age paleosols in the Antarctic Dry Valleys were studied for their compositional variation and concentrations of secondary oxides/coatings in <2mm matrix material in tills. The paleosols date to between 10–18Ma by 10 Be, forming prior to and just following the transition from warm-based to cold-based ice, when the climate is thought to have entered a prolonged cold/dry period...
