Figure 5From: Parallel evolution controlled by adaptation and covariation in ammonoid cephalopodsEvolution of Dmx, FCI, NLb and OLb in auguritids and pinacitids. Bivariate plots of the evolution of adult size, flank convergence index, number of lobes and relative depth of the lateral lobe through the phylogenetic sequence of the two studied ammonoid lineages, separately. Grey line indicates empirical evolutionary trend.Back to article page
