Point clouds for the two samples show a homogeneous sample in the middle Eocene and a heterogeneous one in the upper Eocene. The two clusters in the upper Eocene sample are shown in different symbols and colours. Significant outliers at the 5% level are denoted in solid symbols but were retained for all analyses, as conclusions were not altered qualitatively (see "Model Diagnostics").
