摘要

目前的工作涉及圣地亚哥(卡斯帕·雅各布)罗斯(1850-1924)收藏在苏黎世大学古生物研究所和博物馆的异种人,这是欧洲最重要的阿根廷更新世哺乳动物收藏之一。罗斯是一位来自瑞士的古生物学家,他在阿根廷潘潘地区勘探和收集了大量的更新世巨型动物。xenarthrans是苏黎世收藏的主要代表,有150个标本。自1920年以来,该材料未作修订,仍在研究中。本研究对应于114个重新分配的分类修订,从而记录了异种鱼的多样性并讨论了它们的古生态学。这种多样性反映了潘潘地区更新世时期的古生态,以及影响该地区古环境的各种非生物事件。在热带树懒中,树懒以Mylodontinae和Scelidotheriinae的多样性和丰度最高,而在热带树懒中,Glyptodontinae和Neosclerocalyptinae的动物群可能以Glyptodontinae和Neosclerocalyptinae的代表性较高。这四个支系代表了两个具有高生态耐受性的物种(例如,Glyptodon munizi;Catonyx tarijensis)和生态上高度特化的物种(如Neosclerocalyptus paskoensis;Scelidotherium leptocephalum)。这种生态多样性的存在突出了潘潘地区作为古生态和古环境重建的重要兴趣。补充信息:在线版本包含补充资料,下载地址:10.1186/s13358-023-00265-7。

Xenarthrans of the collection of Santiago Roth from the Pampean Region of Argentina (Pleistocene), in Zurich, Switzerland.

The present work concerns xenarthrans from the collection of Santiago (Kaspar Jakob) Roth (1850-1924) housed at the Palaeontological Institute and Museum of the University of Zurich, one of the most important collections of Pleistocene mammals from Argentina in Europe. Roth was a paleontologist originally from Switzerland who prospected and collected a large amount of Pleistocene megafauna of the Pampean Region of Argentina. The xenarthrans are the main representatives of this collection in Zurich, with 150 specimens. Since 1920, this material has not been revised and is under studied. The present investigation corresponds to a taxonomic revision resulting in 114 reassignments, leading to document xenarthran diversity and discuss their paleoecologies. The high diversity reflects the paleoecology of the Pampean Region during the Pleistocene, with the various abiotic events that impacted the paleoenvironment of this region. Within the Cingulata, the Pampean Region fauna was probably dominated by glyptodonts with a high representation of Glyptodontinae and Neosclerocalyptinae while within the sloths the highest diversity and abundance is found in the Mylodontinae and Scelidotheriinae. These four clades represent both species with high ecological tolerance (e.g., Glyptodon munizi; Catonyx tarijensis) and ecologically highly specialized species (e.g., Neosclerocalyptus paskoensis; Scelidotherium leptocephalum). The presence of such ecological diversity underlines the status of the Pampean Region as a major interest for paleoecological and paleoenvironmental reconstruction.

期刊介绍: The Swiss Journal of Palaeontology publishes original research and review articles of interest to the international community in the fields of palaeontology, taxonomy and systematics, while recognising at the same time the importance of documenting high-quality palaeontological data in a regional context. Palaeobiology in combination with alpha taxonomy is a core topic of the journal. Submitted papers should have an appeal as wide as possible, directed towards an international readership. Contributions should not have been simultaneously submitted elsewhere, and the overlap of content between related articles should be minimal. Duplications of text and the use of previously published illustrations without adequate citation are unacceptable. If a manuscript has two or more authors, both or all have to sign to confirm they all were involved in the work and have agreed to its submission. The preferred manuscript language is UK English, but consistently used US English is also acceptable. We encourage the publication of proceedings of international meetings as well as special thematic issues. Short contributions and book reviews are also accepted. An international editorial team as well as guest editors guarantee that the thematic issues as well as all articles in regular issues are peer-reviewed and meet the highest standards.
