Figure 32 in The postcranial anatomy of Whatcheeria deltae and its implications for the family Whatcheeriidae
Figure 32. Principal components analysis visualizing comparisons of forelimb/hindlimb length, forelimb/trunk length, and hindlimb/trunk length ratios from Table 2. A, PCA results with schematic representations of the three principal morphotypes and their corresponding areas of morphospace; B, phylomorphospace based on A with colours and symbols representing stem tetrapods, stem lissamphibians (temnospondyls) and stem amniotes. The phylogenetic scheme in B is based on (Ruta & Coates, 2007), assuming a temnospondyl origin of lissamphibians, a monophyletic Whatcheeriidae containing Whatcheeria and Pederpes, and a stem amniote identity for embolomeres. Skulls for silhouettes in A are based on the skull of Acanthostega in (Porro et al., 2015). See Supporting Information, Additional results from Principal Components Analysis.
