Figure 5From: Algorithmic approaches to aid species' delimitation in multidimensional morphospaceThe difference between the two clusters in the upper Eocene sample in four of the raw morphological traits was often clear. The thick bar inside each box is the median, with the box extremities representing the inter-quartile range. The limits of each whisker are 1.5*(inter-quartile range), values beyond which are denoted by open circlesBack to article page
