摘要

在英国约克郡克利夫兰盆地Scalby组Long Nab段发现了一种罕见的中侏罗世大型兽脚亚目恐龙化石。这是自1934年克利夫兰盆地首次发现这种类型的标本以来，仅有的第六个标本。目前的标本与以前的一些标本属于相同的，但略有改变的形态型Bxviii，因为它显示出包括细长的后足部在内的其他特征。该标本属于巨龙属，可能是由一种类似巨龙的兽脚亚目恐龙制造的。后足部的拉长可能是休息或蹲伏行为的结果。

A new giant theropod dinosaur track from the Middle Jurassic of the Cleveland Basin, Yorkshire, UK

A new specimen of a rare large theropod dinosaur print of Middle Jurassic age is described from the Long Nab Member of the Scalby Formation, Cleveland Basin, Yorkshire. This is only the sixth specimen of this type recorded from the Cleveland Basin since they were first discovered in 1934. The present specimen is included in the same, but slightly modified morphotype Bxviii as some of the previous ones, since it shows additional features including an elongated metapodium. The specimen is assigned to the ichnogenus Megalosauripus , and was possibly made by a Megalosaurus -like theropod. The elongated metapodium may be the result of resting or crouching behaviour.

期刊介绍： The Proceedings of the Yorkshire Geological Society (PYGS) has been published without a break since 1839. It is one of the leading journals of British geology. Each year two parts are issued containing original research papers on all aspects of geology. Traditionally the Proceedings has given particular attention to the geology of northern England and its neighbouring areas. The submission of papers on related topics but of a more general interest is encouraged. All papers are subjected to the full scrutiny of two independent referees.
