Figure 3 in Osteological characters of birds and reptiles are more congruent with molecular phylogenies than soft characters are

Figure 3. Differences in pooled average character transition ages in millions of years between morphological partitions in all bird and squamate datasets. Dashed lines indicate mean ages of osteological (older) and non-osteological (younger) characters. Data is coloured by partition, with osteological data in purple and non-osteological data in green.
