Abstract

arising from F. Saleh et al. Nature Ecology & Evolution https://doi.org/10.1038/s41559-024-02331-w (2024)

Saleh et al.¹ announced the Cabrières Biota as a new exceptionally preserved fossil assemblage (Konservat-Lagerstätte) of Early Ordovician age dominated by sponges and algae. New deposits of this type are needed to better understand Ordovician ecology and biodiversification and the Cabrières assemblage was presented as a major advance in knowledge of Ordovician polar communities¹. However, the specimens identified as sponges, algae, a worm, a hemichordate tube and a lobopod (that is, all of the non-arthropod exceptionally preserved taxa) appear to be trace fossils, mostly burrows containing faecal pellets. Thus, the Cabrières fossils do not constitute an exceptionally preserved assemblage and the conclusions relating to polar palaeoecology cannot be supported.

卡布里埃生物塔不是啤酒馆

源于 F. Saleh 等人的文章《自然生态与进化》 https://doi.org/10.1038/s41559-024-02331-w (2024)。Saleh 等人1 宣布卡布里埃生物群是一个新的保存异常完好的化石群（Konservat-Lagerstätte），其时代为早奥陶纪，以海绵和藻类为主。为了更好地了解奥陶纪生态学和生物多样性，需要新的此类沉积物，卡布里埃生物群被认为是奥陶纪极地群落知识的一大进步1。然而，被鉴定为海绵、藻类、一种蠕虫、一种半脊管动物和一种叶足动物的标本（即所有保存异常的非节肢动物类群）似乎都是痕量化石，大多是含有粪便颗粒的洞穴。因此，卡布里埃化石并不构成异常保存的化石群，与极地古生态学有关的结论也无法得到支持。

期刊介绍： Nature Ecology & Evolution is interested in the full spectrum of ecological and evolutionary biology, encompassing approaches at the molecular, organismal, population, community and ecosystem levels, as well as relevant parts of the social sciences. Nature Ecology & Evolution provides a place where all researchers and policymakers interested in all aspects of life's diversity can come together to learn about the most accomplished and significant advances in the field and to discuss topical issues. An online-only monthly journal, our broad scope ensures that the research published reaches the widest possible audience of scientists.
