Figure 10 in The exceptionally well-preserved Sauropleura scalaris (Nectridea: Urocordylidae) from the late Carboniferous of the Czech Republic: new information on ontogeny, lateral line and tail

Figure 10. Comparison of ossification sequences of neurocranial elements and the relative timing of their first appearance during ontogenetic development in selected early tetrapods. Elements within the same box appear at the same time. Otic capsules are marked in bold. Ossification sequences are based on the data from Smithson (1982) and Godfrey (1989b) for Greererpeton Romer, 1969, Vallin and Laurin (2004) and Olori (2015) for Microbrachis Frič, 1875, Witzmann (2006) for Archegosaurus Goldfuss, 1847, and Schoch and Witzmann (2009) for Sclerocephalus Goldfuss, 1847.
