Individuals at the centres of their clusters, identified as that with the minimum summed pairwise distance between it and all other individuals in their respective clusters. Panel A is from the middle Eocene sample, with B and C being from the two upper Eocene clusters. These images have been cropped and are therefore no longer to scale; high-quality SEM images are available in [40].
