New Swartpuntia occurrence found within the Aar Member
A new occurrence of Swartpuntia germsi is reported from Farm Aar near Aus in southern Namibia. It is preserved as incomplete part/counterpart in two dimensions, with a folded petaloid. Stratigraphically correlated to a minimum depositional age of 547.32 ± 0.31 Ma, this represents the oldest global occurrence of Swartpuntia and documents a unique style of preservation within the Nama Group. Lastly, the occurrence increases the taxonomic and ecological diversity preserved at Farm Aar, making Farm Aar one of the only locations to preserve all common forms of Erniettomorph taxa.
期刊介绍：
Gondwana Research (GR) is an International Journal aimed to promote high quality research publications on all topics related to solid Earth, particularly with reference to the origin and evolution of continents, continental assemblies and their resources. GR is an "all earth science" journal with no restrictions on geological time, terrane or theme and covers a wide spectrum of topics in geosciences such as geology, geomorphology, palaeontology, structure, petrology, geochemistry, stable isotopes, geochronology, economic geology, exploration geology, engineering geology, geophysics, and environmental geology among other themes, and provides an appropriate forum to integrate studies from different disciplines and different terrains. In addition to regular articles and thematic issues, the journal invites high profile state-of-the-art reviews on thrust area topics for its column, ''GR FOCUS''. Focus articles include short biographies and photographs of the authors. Short articles (within ten printed pages) for rapid publication reporting important discoveries or innovative models of global interest will be considered under the category ''GR LETTERS''.
