A diverse diapsid tooth assemblage from the Early Triassic (Driefontein locality, South Africa) records the recovery of diapsids following the end-Permian mass extinction
Fig 11
Ordination plot of first two major nMDS axes of diapsid tooth morphospace and temnospondyls.
Colored, transparent polygons are convex hulls of each reptile tooth morphotype and the temnospondyl morphotype, colors and symbols correspond to different morphotypes. There is some overlap in morphotypes A and C and between morphotype D and temnospondyl teeth as the new analysis results in new optimal distances. The first major axis is still split by serrations, though now positive weights are non-serrated and negative weights are serrated.
