Abstract

An enigmatic partial trackway from the Aalenian to Bathonian (Middle Jurassic) Ravenscar Group of Whitby, North Yorkshire bears a striking resemblance to the pterosaur trace Pteraichinus. It also displays some similarities with the xiphosuran trackway Kouphichnium. The trackway is assigned to a new ichnogenus and ichnospecies Pseudopteraichnus whitbyensis. Using tetrapods as a comparator, Pseudopteraichnus is characterised by an elongate ‘heel’, a sub-triangular ‘tarsus’ and four unequal ‘digits’. A possible fifth digit is located posterolaterally. The track maker is unknown.

来自英格兰约克郡中侏罗世拉文斯卡群的神秘化石

在北约克郡惠特比，从阿勒世到Bathonian（中侏罗世）的Ravenscar群的神秘部分轨迹与翼龙的痕迹有着惊人的相似之处。它也显示出与剑龙轨迹的一些相似之处。该轨迹被划分为一个新鱼属和一个新鱼种whitbyensis Pseudopteraichnus。以四足动物作为比较，伪翅足动物的特征是有一个细长的“足跟”，一个次三角形的“跗骨”和四个不相等的“趾”。第五指可能位于后外侧。轨道制造商是未知的。

期刊介绍： The Proceedings of the Geologists'' Association is an international geoscience journal that was founded in 1859 and publishes research and review papers on all aspects of Earth Science. In particular, papers will focus on the geology of northwestern Europe and the Mediterranean, including both the onshore and offshore record. Following a long tradition, the PGA will focus on: i) a range of article types (see below) on topics of wide relevance to Earth Sciences ii) papers on aspects of Earth Science that have societal relevance including geoconservation and Earth management, iii) papers on palaeoenvironments and palaeontology of the Mesozoic and Cenozoic, iv) papers on aspects of Quaternary geology and climate change, and v) papers on the history of geology with particular reference to individuals that have shaped the subject. These topics will also steer the content of the themes of the Special Issues that are published in the PGA.
