Figure S4 from Does exceptional preservation distort our view of disparity in the fossil record?

The effect of missing data on the distances of sauropterygian taxa from the morphospace origin. Linear regressions between a taxon’s percentage missing data and its Pythagorean distance from the origin of PCO space on the first two PCO axes. PCO was performed with and without negative eigenvalue correction on raw, Generalised Euclidean (GED), Gower Coefficient (GOW) and Maximum Observable Rescaled (MAX) distance matrices generated from the cladistic matrix of Benson and Bowdler [43].
