BEAST xml files

These are three relevant files for time-calibration analyses of Odontomachus. The multi-locus alignment with one specimen per species is in nexus format, whereas two xml files can be found, one following the calibration density approach (minimum ages of fossils) and the second following the Fossilized Birth Death model.本数据集包含用于钝颚蚁属（Odontomachus）时间校准分析的三份相关文件。其中，每份物种对应单份标本的多位点序列比对文件采用NEXUS格式存储；另有两份XML格式文件，其一采用校准密度法（基于化石最小年代），其二采用化石出生-死亡（Fossilized Birth Death）模型。
