Data on taxon preservation from three Burgess Shale-type deposits

The dataset represents the type of anatomical structures found in all fossil taxa from three Burgess Shale-type deposits: the Burgess Shale (Cambrian, Canada), the Chengjiang Biota (Cambrian, China) and the Fezouata Shale (Ordovician Morocco). These structures were divided into five categories: mineralized, sclerotized, and cuticularized parts, and soft tissues that are in direct contact with sea water and internal organs. These data were acquired during a 3-month period from scientific publications, books, and through examinations of museum collections. This dataset allows for the exploration of the difference in preservation patterns between three iconic sites and shows that the proportion of the five identified structures differs between them. These data can be reused for comparison when investigating the preservation potential of a newly discovered locality with soft fossil preservation and to help reconstruct paleo-biodiversity independently from preservation biases.本数据集涵盖了三处布尔吉斯页岩型（Burgess Shale-type）沉积矿床中所有化石类群的解剖结构类型，这三处遗址分别为：加拿大寒武纪布尔吉斯页岩（Burgess Shale）、中国寒武纪澄江生物群（Chengjiang Biota）以及摩洛哥奥陶纪费祖阿塔页岩（Fezouata Shale）。 这些解剖结构被划分为五大类别：矿化结构、硬化结构、角质化结构、与海水直接接触的软组织以及内部器官。 本数据集的数据采集工作历时3个月，数据来源涵盖学术期刊论文、专业专著以及博物馆馆藏标本的检视工作。 本数据集可用于探究三处经典化石遗址的化石保存模式差异，研究结果表明，五类已识别解剖结构的占比在三处遗址中存在显著区别。 该数据集可被重复利用，用于在研究具备软躯体化石保存特征的新发现化石点的保存潜力时开展对比分析，同时可辅助摆脱保存偏差的影响，独立重建古生物多样性。
