摘要

在英国约克郡惠特比一处悬崖坠落的雷文斯卡组砂岩上，发现了一对轮廓分明的颚和趾印，这很可能是一只蜥脚类恐龙的足迹。脚趾印显示了四个脚趾，也可能是五个脚趾，因此非常类似于Brontopodus和Parabrontopodus的脚印。它们在此被称为 Brontopodus cf. pentadactylus Kim 和 Lockley，2012 年。螯部周围有鳞片状的外皮。这些指纹很可能是臀部高度在 1.92 米至 2.83 米之间的蜥脚类动物所留下的。

Sauropod manus and pes prints with impressions of integument from the Ravenscar Group (Middle Jurassic) of Whitby, Yorkshire, England

Well-defined manus and pes print couple, likely from a trackway attributable to a sauropod dinosaur are revealed on a fallen block of Ravenscar Group sandstones in a cliff fall at Whitby, Yorkshire, England. The pes print displays four, possibly five toes and thus closely resembles that of the ichnogenera Brontopodus and Parabrontopodus. They are here referred to Brontopodus cf. pentadactylus Kim and Lockley, 2012. Impressions of a scaled integument are present around parts of the pes. The prints were likely made by a sauropod with a hip height of between 1.92 m and 2.83 m.

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.
