Diet of Mesozoic toothed birds (Longipterygidae) inferred from quantitative analysis of extant avian diet proxies

Spreadsheets and R code used for data analysis and figure creation in the BMC Biology paper "Diet of Mesozoic toothed birds (Longipterygidae) inferred from quantitative analysis of extant avian diet proxies" (doi 10.1186/s12915-022-01294-3). Outputs from all finite element models are provided as well. A README text file is included to explain the file types included and best practices for running them to recreate our outputs.本数据集包含发表于《BMC生物学》（BMC Biology）的论文《基于现生鸟类食性代理指标定量分析推断的中生代齿鸟（长翼鸟科）食性》（DOI: 10.1186/s12915-022-01294-3）中用于数据分析与图表制作的电子表格与R代码；同时提供所有有限元模型（finite element models）的输出结果。此外附带README文本文件，用以说明本数据集包含的文件类型，以及运行相关文件复现本研究输出结果的最佳实践。
