摘要

摘要在荷兰的马斯特里赫特类型区发现了一只与Ctenochelys有亲缘关系的晚白垩世海龟的下颌骨。三角形下颌骨有发育良好的联合骨脊，两侧被磨痕表面的大凹区包围。这是马斯特里赫特类型区首次发现栉水母。这一发现增加了从马斯特里赫特类型地区已知的海龟动物群的多样性。

The first report of Chelonioidea cf. Ctenochelys from the Late Cretaceous of the Maastrichtian type area

Abstract A mandible of a Late Cretaceous sea turtle with affinities to Ctenochelys is reported from the Maastrichtian type area of the Netherlands. The triangular mandible has a well-developed symphyseal ridge surrounded on both sides by large, concave areas on the triturating surface. It represents the first potential occurrence of Ctenochelys from the Maastrichtian type area. This finding increases the diversity of the turtle fauna known from the Maastrichtian type area.

期刊介绍： Netherlands Journal of Geosciences - Geologie en Mijnbouw is a fully open access journal which publishes papers on all aspects of geoscience, providing they are of international interest and quality. As the official publication of the ''Netherlands Journal of Geosciences'' Foundation the journal publishes new and significant research in geosciences with a regional focus on the Netherlands, the North Sea region and relevant adjacent areas. A wide range of topics within the geosciences are covered in the journal, including "geology, physical geography, geophyics, (geo-)archeology, paleontology, hydro(geo)logy, hydrocarbon exploration, modelling and visualisation." The journal is a continuation of Geologie and Mijnbouw (published by the Royal Geological and Mining Society of the Netherlands, KNGMG) and Mededelingen Nederlands Instituut voor Toegepaste Geowetenschappen (published by TNO Geological Survey of the Netherlands). The journal is published in full colour.
