Figure 10 in Osteology and relationships of the temnospondyl genus Sclerocephalus

Figure 10. Phylogenetic relationships of late Palaeozoic temnospondyls, with focus on the position and intrarelationships of the genus Sclerocephalus. Derived from a strict consensus of three most parsimonious trees found by PAUP 3.1: A, general topology, with supporting synapomorphies mapped at each node (the numbers refer to the character list, 'H' indicates homoplastic character states); B, intrarelationships within the genus Sclerocephalus as found by the present analysis.
