摘要

在阿尔及利亚下切利夫盆地的一个舌骨炎右瓣外表面上，描述了一个精细的蚀刻痕迹，Renichnus arcuatus。这是地中海南部海岸上新世以来的第一份精美蚀刻版画记录。负责蚀刻的装饰使用双壳壳作为附着的硬基底。vermetids使用粘液网进食，如果它们在活的双壳类动物身上定居，它们可能会从宿主的进食流中受益。类似蚀刻记录的古地理表明，上新世的地中海地区普遍存在vermetids。

First record of the trace fossil Renichnus arcuatus Mayoral, 1987 in the Pliocene of Sidi Brahim (Lower Chelif Basin, NW Algeria)

A vermetid etching trace, Renichnus arcuatus, has been described from the outer surface of a single right valve of Hyotissa hyotis from the Lower Chelif Basin, Algeria. This is the first record of vermetid etchings from the Pliocene of the Mediterranean Sea's southern coast. The vermetids responsible for the etchings used bivalve shells as a hard substrate for attachment. The vermetids used mucus nets to feed and they may have benefitted from the feeding currents of the host if they colonized a living bivalve. The palaeogeography of similar etching records indicates that vermetids were common in the Mediterranean region in the Pliocene.

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.
