TL;DR: In this paper, the role of juvenile mantle addition during the early crustal growth at the supercontinental margin of Gondwana has been investigated in a large area of southern South America, including the 700'×'600'km type sector of the orogen in the Sierras Pampeanas (27°−33°S), the Precordillera, and northeastern Patagonia.

TL;DR: In this paper, the provenance and tectonic setting of the Middle Cambrian and Ordovician siliciclastic deposits and associated volcanic rocks of the Bavarian Facies, Franconia, Germany, in the Saxothuringian Zone of the Variscan orogen were examined.

TL;DR: Recently, the lower Cambrian Emu Bay Shale (EBS) has been used to provide critical insights into the tempo of the Cambrian explosion of animals, such as the origin and seemingly rapid evolution of arthropod compound eyes, as well as extending the geographical ranges of several groups to the East Gondwanan margin, supporting close faunal affinities with South China as mentioned in this paper.
Abstract: Recent fossil discoveries from the lower Cambrian Emu Bay Shale (EBS) on Kangaroo Island, South Australia, have provided critical insights into the tempo of the Cambrian explosion of animals, such as the origin and seemingly rapid evolution of arthropod compound eyes, as well as extending the geographical ranges of several groups to the East Gondwanan margin, supporting close faunal affinities with South China. The EBS also holds great potential for broadening knowledge on taphonomic pathways involved in the exceptional preservation of fossils in Cambrian Konservat-Lagerstatten. EBS fossils display a range of taphonomic modes for a variety of soft tissues, especially phosphatization and pyritization, in some cases recording a level of anatomical detail that is absent from most Cambrian Konservat-Lagerstatten.

TL;DR: The Toploje Member chert is a Roadian to Wordian autochthonous-parautochthonsous silicified peat preserved within the Lambert Graben, East Antarctica as mentioned in this paper, which preserves a remarkable sample of terrestrial life from high-latitude central Gondwana prior to the Capitanian mass extinction event from both mega- and microfossil evidence that includes cryptic components rarely seen in other fossil assemblages.

TL;DR: A study of the abundant and undescribed isolated and associated bones and teeth from the La Amarga Formation (Barremian of Neuquen, Argentina) permitted the recognition of additional clades of sauropod dinosaurs: basal titanosauriforms, both basal and derived titanosaurs, and rebbachisauroid diplodocoids as mentioned in this paper.
