Fig. 8. Stratocladogram of tetrapod phylogeny. Although extending the known body fossil record, the stratigraphic position of the diadectomorph and synapsid footprints from the Bochum Formation of western Germany fits well the phylogenetic pattern. Black bars indicate the known record of skeletal remains (Reisz 1986; Kissel and Reisz 2004a, b). Cladogram topology and minimum times of divergence are based on Kissel and Reisz (2004a, b), Müller and Reisz (2004), and Reisz (2007). The chronostratigraphic scale is adopted from Menning (2005).
