—The presence of a new taxon, Duraznovis gallegoi new genus new species is reported and described from an early Late Triassic (Carnian) deposit in Argentina. Two specimens, recovered from the Quebrada del Durazno locality, uppermost levels of the Potrerillos Formation, Cuyana Basin (Mendoza), are represented by the molds of their shield and imprints of soft parts. The identity of these specimens appears enigmatic but closely resembles in the possession of a generalized arthropod morphology and a distinctive combination of characters, to living and fossil representatives of xiphosurans (Chelicerata) and notostracans (Branchiopoda). The new fossils are associated with a rich biota comprising abundant insects, spinicaudatans, plants, and scarce fish remains living in semipermanent swamps and/or ponds within a delta plain environment with intermittent episodes of flooding, in a warm temperate and humid megamonsoonal climate during Triassic times. In this context, we analyze the taphonomic and ecological implications of their presence. Lastly, these unique specimens at the Quebrada del Durazno locality adds to the diversity of the biota, revealing the importance of this site as an exceptional paleontological Triassic deposit.

一种来自冈瓦纳(阿根廷)西南部上三叠纪(卡尼阶)的神秘节肢动物 — 勘误表

— 阿根廷晚三叠世早期(卡尼阶)矿床报告和描述了一个新分类群 Duraznovis gallegoi 新属新种的存在。从 Quebrada del Durazno 地区发现的两个标本,即 Cuyana 盆地(门多萨)Potrerillos 组的最上层,由它们的盾牌模具和柔软部分的印记代表。这些标本的身份看似神秘,但在拥有普遍的节肢动物形态和独特的特征组合方面与 xiphosurans (Chelicerata) 和 notostracans (Branchiopoda) 的活体和化石代表非常相似。新化石与丰富的生物群有关,包括丰富的昆虫、棘尾纲动物、植物、稀有的鱼类仍然生活在三角洲平原环境中的半永久性沼泽和/或池塘中,在三叠纪时期处于暖温带和潮湿的巨型季风气候中,间歇性洪水发作。在这种情况下,我们分析了它们存在的埋藏学和生态学意义。最后,Quebrada del Durazno 地区的这些独特标本增加了生物群的多样性,揭示了该地点作为特殊古生物三叠纪沉积物的重要性。UUID:http://zoobank.org/8d1194c2-170c-4b7a-b0c6-5c08b0974d95 揭示了该地点作为特殊古生物三叠纪矿床的重要性。UUID:http://zoobank.org/8d1194c2-170c-4b7a-b0c6-5c08b0974d95 揭示了该地点作为特殊古生物三叠纪矿床的重要性。UUID:http://zoobank.org/8d1194c2-170c-4b7a-b0c6-5c08b0974d95
