Clam shrimp from the Purbeck Limestone Formation

This dataset contains all the clam shrimp specimens collected from the Purbeck Limestone Formation in four sections in the southern UK: 1) northern Durlston Bay section in Swanage: the fossil horizon is the Freshwater Beds. One species was recovered, i.e. Liograpta subquadrata; 2) southern Durlstone Bay section in Swanage: the fossil horizon is the Freshwater Beds. One species was recovered, i.e. Liograpta subquadrata; 3) east Lulworth Cove section near West Lulworth: the fossil horizon is the Freshwater Beds. Two clam shrimp species were recovered, i.e. Carapacestheria? lulworthensis sp. nov., and Liograpta subquadrata; 4) Bacon Hole of Mupe Bay section: the fossil horizon is the Caps and Dirt Beds, only one specimen and its counter part were recovered. Because no ornamentation was preserved, the specimens can not be identified. In the data sets, the dementions of the newly collected specimens are included, such as the number of growth lines, the caarapace length, the carapace hight, and the ratio of Height/Length. All specimens are preserved in the collection of Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences, and the register specimen numbers are also clearly shown in the dataset.

本数据集收录了英国南部4条剖面的普尔贝克石灰岩组（Purbeck Limestone Formation）中采集的全部叶肢介（clam shrimp）标本：
1）斯沃尼奇（Swanage）境内的多尔斯顿湾（Durlston Bay）北段剖面：化石产出层位为淡水岩层（Freshwater Beds），共采获1个物种：亚方形丽肢介（Liograpta subquadrata）；
2）斯沃尼奇境内的多尔斯顿湾（Durlstone Bay）南段剖面：化石产出层位为淡水岩层（Freshwater Beds），共采获1个物种：亚方形丽肢介（Liograpta subquadrata）；
3）西卢尔沃思（West Lulworth）附近的卢尔沃思湾（Lulworth Cove）东段剖面：化石产出层位为淡水岩层（Freshwater Beds），共采获2种叶肢介：卢尔沃思壳肢介？新种（Carapacestheria? lulworthensis sp. nov.）与亚方形丽肢介（Liograpta subquadrata）；
4）穆普湾（Mupe Bay）的培根洞（Bacon Hole）剖面：化石产出层位为顶盖与杂土层（Caps and Dirt Beds），仅采获1件标本及其对应模。由于未保存壳饰结构，该标本无法进行物种鉴定。
本数据集包含了新采集标本的各项形态参数，包括生长线数目、壳瓣长度、壳瓣高度以及高长比。所有标本均保存于中国科学院南京地质古生物研究所馆藏，数据集内亦明确标注了每件标本的登记编号。
