Abstract

Actinopterygii (ray-finned fishes) and Elasmobranchii (sharks, skates and rays) represent more than half of today's vertebrate taxic diversity (approximately 33000 species) and form the largest component of vertebrate diversity in extant aquatic ecosystems. Yet, patterns of 'fish' evolutionary history remain insufficiently understood and previous studies generally treated each group independently mainly because of their contrasting fossil record composition and corresponding sampling strategies. Because direct reading of palaeodiversity curves is affected by several biases affecting the fossil record, analytical approaches are needed to correct for these biases. In this review, we propose a comprehensive analysis based on comparison of large data sets related to competing phylogenies (including all Recent and fossil taxa) and the fossil record for both groups during the Mesozoic-Cainozoic interval. This approach provides information on the 'fish' fossil record quality and on the corrected 'fish' deep-time phylogenetic palaeodiversity signals, with special emphasis on diversification events. Because taxonomic information is preserved after analytical treatment, identified palaeodiversity events are considered both quantitatively and qualitatively and put within corresponding palaeoenvironmental and biological settings. Results indicate a better fossil record quality for elasmobranchs due to their microfossil-like fossil distribution and their very low diversity in freshwater systems, whereas freshwater actinopterygians are diverse in this realm with lower preservation potential. Several important diversification events are identified at familial and generic levels for elasmobranchs, and marine and freshwater actinopterygians, namely in the Early-Middle Jurassic (elasmobranchs), Late Jurassic (actinopterygians), Early Cretaceous (elasmobranchs, freshwater actinopterygians), Cenomanian (all groups) and the Paleocene-Eocene interval (all groups), the latter two representing the two most exceptional radiations among vertebrates. For each of these events along with the Cretaceous-Paleogene extinction, we provide an in-depth review of the taxa involved and factors that may have influenced the diversity patterns observed. Among these, palaeotemperatures, sea-levels, ocean circulation and productivity as well as continent fragmentation and environment heterogeneity (reef environments) are parameters that largely impacted on 'fish' evolutionary history, along with other biotic constraints.

摘要

硬骨鱼纲(有鳍鱼类)和软骨鱼纲(鲨鱼、鳐鱼和魟鱼)代表了当今脊椎动物分类多样性的一半以上(约 33000 种),也是现存水生生态系统中脊椎动物多样性的最大组成部分。然而,鱼类进化历史的模式仍未被充分了解,以前的研究通常将这两个群体分开处理,主要是因为它们的化石记录组成和相应的采样策略存在差异。由于古生物多样性曲线的直接解读受到影响化石记录的几种偏差的影响,因此需要分析方法来纠正这些偏差。在这篇综述中,我们提出了一种基于比较大的数据集的综合分析,这些数据集涉及到相互竞争的系统发育(包括所有现代和化石分类群)以及这两个群体在中生代-新生代期间的化石记录。这种方法提供了有关“鱼类”化石记录质量以及经过修正的“鱼类”深远时间系统发育古生物多样性信号的信息,特别强调了多样化事件。由于分类信息在经过分析处理后得以保留,因此识别出的古生物多样性事件在数量和质量上都得到了考虑,并将其置于相应的古环境和生物背景下。结果表明,软骨鱼类的化石记录质量更好,因为它们的化石分布类似于微化石,而且它们在淡水系统中的多样性很低,而淡水硬骨鱼类在这个领域的多样性较高,但保存潜力较低。在家族和属的水平上,软骨鱼类、海洋和淡水硬骨鱼类都确定了几个重要的多样化事件,即早-中侏罗世(软骨鱼类)、晚侏罗世(硬骨鱼类)、早白垩世(软骨鱼类、淡水硬骨鱼类)、塞诺曼期(所有群体)和古新世-始新世期间(所有群体),后两个时期是脊椎动物中两个最异常的辐射时期。对于这些事件中的每一个,以及白垩纪-古近纪灭绝事件,我们都对所涉及的分类群以及可能影响所观察到的多样性模式的因素进行了深入的回顾。其中,古温度、海平面、海洋环流和生产力以及大陆分裂和环境异质性(珊瑚礁环境)是对“鱼类”进化历史产生重大影响的参数,与其他生物限制因素一起。
