Purbeck Group
http://dbpedia.org/resource/Purbeck_Group an entity of type: Species
Le faciès purbeckien est un faciès sédimentaire de calcaires souvent fins, de marnes, d'argiles et d'évaporites, déposé dans des environnements peu profonds souvent de type laguno-lacustres. Son âge couvre la partie terminale du Tithonien (dernier étage du Jurassique) et la partie inférieure du Berriasien (premier étage du Crétacé). Le faciès purbeckien affleure sur de grandes étendues (sud de l’Angleterre, Bassin parisien, Bassin aquitain, Jura, Bavière, etc.).

普贝克层 又译珀贝克层。英国侏罗系最顶部的地层单元（侏罗纪约始于1.9亿年前，持续约5400万年）。位于波特兰层之上，代表普贝克阶（侏罗纪的一格世界性标准时间地层单元）。该层岩石变化很大，显示出侏罗纪地理条件的主要更替。

The Purbeck Group is an Upper Jurassic to Lower Cretaceous lithostratigraphic group (a sequence of rock strata) in south-east England. The name is derived from the district known as the Isle of Purbeck in Dorset where the strata are exposed in the cliffs west of Swanage. The Purbeck Group is famous for its fossils of reptiles and early mammals. This sequence of rocks has gone by various names in the past including amongst others the Purbeck Beds, Purbeck Formation, Purbeck Limestone Formation and Purbeck Stone.

The Purbeck Group is famous for its fossils of reptiles and early mammals. This sequence of rocks has gone by various names in the past including amongst others the Purbeck Beds, Purbeck Formation, Purbeck Limestone Formation and Purbeck Stone. Rocks of this age have in the past been called the Purbeckian stage by European geologists. The Purbeckian corresponds with the Tithonian to Berriasian stages of the internationally used geologic timescale.
