Abstract

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.

在阿尔（Aar）岩层中发现新的 Swartpuntia 分布区

据报道，纳米比亚南部奥斯附近的阿尔农场新发现了一种 Swartpuntia germsi。它以不完整的部分/对应部分的形式保存在二维空间中，并带有一个折叠的花瓣。从地层学角度看，其最小沉积年龄为 547.32 ± 0.31 Ma，这是全球发现的最古老的疣螈，并记录了纳马群中一种独特的保存方式。最后，这一发现增加了阿尔农场保存的分类学和生态学多样性，使阿尔农场成为保存所有常见Erniettomorph分类群的唯一地点之一。

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''.
