Data for: High-resolution taphonomic and palaeoecological analyses of the Jurassic Yanliao Biota of the Daohugou area, northeastern China

The six data files contain all data used for statistical analyses in this research. The file “Faunal composition (aquatic communities)” contains mean densities of clam shrimp, mayfly nymph and water boatmen on 35 bedding planes from two excavation sites. The file “Faunal composition (terrestrial insects)” contains the composition of terrestrial insects from 11 levels (north site). The file “Fossil preservation” contains data from 9 levels (north site). The preservation quality of terrestrial insects is classified into five taphonomic grades. The exact number of individuals per grade is recorded by taxon in this file. The file “Plan-view orientation” contains data from 9 bedding planes of the north site. The plan-view orientations of aquatic insects are classified into 6 segments. The number of individuals per segment is recorded in this file. The file “Clam shrimp size” contains the individual size of 3869 clam shrimp collected from 19 bedding planes. The file “Clam shrimp size & growth band crowding” contains data of 106 individuals from 4 bedding planes. The presence or absence of growth band crowding and individual size are recorded in this file.本研究用于统计分析的全部数据均包含于这6份数据文件中。 文件"动物群组成（水生群落）"收录了两处发掘点的35个地层层面上，蚌虾（Clam shrimp）、蜉蝣稚虫（Mayfly nymph）以及划蝽（Water boatmen）的平均密度数据。 文件"动物群组成（陆生昆虫）"收录了北部发掘点11个层位的陆生昆虫群落组成数据。 文件"化石保存状态"收录了北部发掘点9个层位的数据。该文件将陆生昆虫的保存质量划分为5个埋藏学等级（Taphonomic grade），并按分类单元（Taxon）记录了每个等级对应的个体精确数量。 文件"平面方位"收录了北部发掘点9个地层层面的数据。该文件将水生昆虫的俯视方位划分为6个区段，并记录了每个区段对应的个体数量。 文件"蚌虾体型"收录了从19个地层层面采集的3869只蚌虾的个体体型数据。 文件"蚌虾体型与生长带拥挤"收录了4个地层层面上106只个体的数据，该文件记录了个体是否存在生长带拥挤现象以及其体型数据。
