Abstract

We study the Late Jurassic (Tithonian) turtle Uluops uluops using micro-computed tomography scans to investigate the cranial anatomy of paracryptodires, and provide new insights into the evolution of the internal carotid artery and facial nerve systems, as well as the phylogenetic relationships of this group. We demonstrate the presence of a canalis caroticus lateralis in Uluops uluops, the only pleurosternid for which a palatine artery canal can be confidently identified. Our phylogenetic analysis retrieves Uluops uluops as the earliest branching pleurosternid, Helochelydridae within Pleurosternidae, and Compsemydidae including Kallokibotion bajazidi within Baenidae, which suggests at least two independent losses of the palatine artery within paracryptodires. We expect future studies will provide additional insights into the evolution of the circulation system of paracryptodires, as well as clarifying relationships along the turtle stem.

晚侏罗世(泰坦纪)龟Uluops Uluops的重新描述和副龟纲的一个新的系统发育假说。

本研究利用微计算机断层扫描技术研究了晚侏罗世(泰坦纪)龟Uluops Uluops的颅骨解剖结构，并为该类群的颈内动脉和面神经系统的进化以及系统发育关系提供了新的见解。我们证明了在Uluops Uluops中存在侧颈动脉管，这是唯一一个可以自信地识别腭动脉管的胸骨。我们的系统发育分析检索到Uluops Uluops是最早分支的胸骨科动物，Helochelydridae属于胸骨科，Compsemydidae包括bajazidi属于Baenidae，这表明在副隐门中至少有两次独立的腭动脉损失。我们期望未来的研究将提供更多的见解，以进一步了解副cryptodires循环系统的演变，以及澄清沿龟茎的关系。补充信息:在线版本包含补充资料，下载地址:10.1186/s13358-021-00234-y。

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.
