A re-description of the late Carboniferous trematopid Actiobates peabodyi from Garnett, Kansas.

Abstract:

:Dissorophoids are a diverse clade of predominantly Permo-Carboniferous temnospondyls with a wide geographic distribution and broad ecological diversity. Each of the various dissorophoid clades first appears in the late Carboniferous, but their records are relatively sparse and fragmentary compared to those of the early Permian when dissorophoids reach their peak diversity and distribution, particularly in terrestrial environments where they are by far the most taxonomically diverse clade of non-amniote tetrapods. This provides an impetus for further study of the late Carboniferous terrestrial dissorophoids in order to contextualize the early stages in the clade's radiation into terrestrial ecosystems. Here we present a re-description of the late Carboniferous trematopid Actiobates peabodyi from Kansas, USA, which is represented by a nearly complete skeleton and which represents the earliest occurrence of trematopids in North America. Only the skull was previously described, and the taxon has been largely overlooked in the context of early terrestrial dissorophoid evolution. Here, we provide an updated cranial description, the first postcranial description, and a discussion of the position of A. peabodyi in the context of olsoniform evolution. Our most significant finding is the characterization of postcranial anatomy that is highly similar to that of later trematopid taxa. This high degree of conservatism indicates that the earliest trematopids were already well-adapted for terrestrial environments, and post-Carboniferous radiations of olsoniforms may be attributed to an expansion of the dryland terrestrial environments in which these taxa already thrived, rather than to novel acquisition of adaptive features later in the clade's evolution.

摘要:

: 重石是一种以石炭-石炭二叠系为主的多种多样的天幕,具有广泛的地理分布和生态多样性。每一种不同的失水枝首先出现在晚石炭世,但与早二叠世相比,它们的记录相对稀疏和零碎,当失水枝达到其多样性和分布的峰值时, 特别是在陆地环境中,它们是迄今为止分类学上最多样化的非羊膜四足动物。这为进一步研究晚石炭世陆相失水体提供了动力,以便将分支辐射的早期阶段融入陆地生态系统。这里我们重新描述了来自美国堪萨斯州的晚石炭纪吸虫活性物质 peabodyi,它以几乎完整的骨骼为代表,代表了北美最早出现的吸虫。以前只描述了头骨,在早期陆相视物演化的背景下,分类单元在很大程度上被忽视了。在这里,我们提供了更新的头颅描述、第一次颅后描述,以及在 olsoniform 进化背景下 a.peabodyi 位置的讨论。我们最有意义的发现是颅后解剖结构的特征与后来的吸虫类群高度相似。这种高度的保守性表明最早的吸虫已经很好地适应了陆地环境, 而后石炭纪的长子辐射可能归因于这些类群已经蓬勃发展的旱地陆地环境的扩展,而不是分支进化后期适应性特征的新获得。本文受版权保护。保留所有权利。

Anatomical Record-Advances in Integrative Anatomy and Evolutionary Biology 期刊简介

英文简介:

The Anatomical Record: Advances in Integrative Anatomy and Evolutionary Biology, an official publication of the American Association of Anatomists, publishes new discoveries in the morphological aspects of molecular, cellular, systems, and evolutionary biology. The journal focuses on major new findings in the anatomical consequences of gene disruption, activation, or over expression upon cell, tissue, or organ architecture and also recognizes the importance of descriptive studies in contemporary research, particularly when framed in the context of experimental models or questions.
