A new sun star (Echinodermata, Asteroidea, Solasteridae) from the mid-Miocene of Lacoste, France

A new genus and species of starfish in the family Solasteridae, Lacosteaster lauerorum gen. et sp. nov., are described from the mid-Miocene of Lacoste, south-east France. The genus differs from all known extant solasterids and the only other fossil (Middle Jurassic) representative of the family in the presence of single, large conical spines on ossicles of the undersurface, and large bladed spines surrounding the mouth.

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.
