Just out @ Palaeontology Vase-shaped microfossils from the Tonian Callison Lake Formation of Yukon, Canada: taxonomy, taphonomy and stratigraphic palaeobiology Author(s) Phoebe A. Cohen, Spencer W. Irvine, Justin V. Strauss Abstract: Vase-shaped microfossils (VSMs), interpreted as the remains of testate amoebae, are found in late Tonian sedimentary rocks around the world. Here we explore the taxonomy, taphonomy and stratigraphical occurrence of VSMs from the Callison Lake Formation of the Coal Creek

Just out @ Marine Micropaleontology Rich shallow-water benthic ecosystem in Late Miocene East Antarctica (Fisher Bench Fm, Prince Charles Mountains) Author(s) Wojciech Majewski, Andrzej Tatur, Jakub Witkowski, Andrzej Gaździcki Abstract: A single shell of a pectenoid bivalve was found in the lower part of the Fisher Bench Formation (Fisher Massif, Prince Charles Mountains). In contrast to glacigenic sediments that form extensive outcrops in this area and are almost barren of foraminifera, small pieces of

Just out @ Journal of Paleolimnology Effects of long term nutrient and climate variability on subfossil Cladocera in a deep, subalpine lake (Lake Garda, northern Italy) Author(s) Manuela Milan, Christian Bigler, Monica Tolotti, Krystyna Szeroczyńska Abstract: Albeit subfossil Cladocera remains are considered as a reliable proxy for tracking historical lake development, they have been scarcely studied in large subalpine lakes south of the Alps. In this study, subfossil Cladocera remains from Lake Garda in northern

Just out | PE Note: New name for the foraminiferal genus Olgia @ Palaeontologia Electronica

Just out @ Palaeontologia Electronica PE Note: New name for the foraminiferal genus Olgia Author(s) Valeria I. Mikhalevich Abstract: The name of the new foraminiferal genus Olgia Mikhalevich, 2011 published in Mikhalevich (2011) is preoccupied by Olgia Radoszkowskii, 1877, a genus of wasp (Radoszkowskii, 1877, p. 33). Thus Olgia Mikhalevich, 2011 is a junior homonym of Olgia Radoszkowskii, 1877. Olgita is here proposed as a new name for Olgia Mikhalevich, 2011. Its taxonomic position remains unchanged: Phylum FORAMINIFERA d’Orbigny, 1826 Class ROTALIATA Mikhalevich, 1980 Subclass

Just out @ Revue de Micropaléontologie Taphonomic and palaeovegetational studies in lower Permian (Asselian-Sakmarian) deposits of Chintalapudi Area, Godavari Graben, South India Author(s) Shreya Mishra, Neerja Jha, Sukhbir Singh Gahalain Abstract: Palynomorphs from lower Permian (Asselian-Sakmarian) deposits from Chintalapudi area of Godavari Graben were used to infer palaeovegetation and palaeoenvironments through palynofacies reconstruction and taphonomic studies. The recovered palynofloral assemblage is dominated by Cordaites with subordinate conifers and glossopterids forming the floral canopy. Fillicopsids, equisetopsids,

Wilmshurst, G. Dunbar, I. Hajdas Abstract: Despite wide-ranging interest in the vegetation and climate of Northland, New Zealand, during the last glacial cycle, the region and timeframe lack quantitative climate reconstructions while land-based pollen records have tended to be poorly dated and
