Abstract

A new species of the “living fossil” crinoid , , is described from lower Campanian phosphatic chalks in southern England and northern France. The squat, robust stalkless crinoid lived in high-energy conditions in phosphate chalk basins, attached to the surface of the basal hardground. Other Cretaceous and lower Paleogene occurrences of the genus, from France, the Czech Republic and Denmark are briefly reviewed.

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.
