FIGURE 1. Cladogram depicting phylogenetic relationships among basal sarcopterygians. Phylogenetic information was mainly compiled from: Cloutier & Ahlberg (1996) and Zhu et al. (2009, 2012) for Sarcopterygii; Zhu et al. (2009) for †Achoania, †Ligulalepis, †Meenmania, †Guiyu, and †Psarolepis; Lu & Zhu (2010) for Onychodontiformes; Friedman (2007b), Dutel et al. (2012), and Zhu et al. (2012) for Actinistia; Ahlberg (1991), Ahlberg et al. (2006), Cione et al. (2007), Cavin et al. (2007), Friedman (2007a), Agnolin (2010), and Clement & Long (2010) for †Diabolepis, †Powichthys, †Youngolepis, and Dipnoi; Cloutier & Ahlberg (1996) and Clement (2001) for Porolepiformes; Ahlberg et al. (2003) and Swartz et al. (2012) for Tetrapodomorpha [despite Holland (2013) having proposed important changes in tetrapodomorph phylogeny, his work was not here considered because many dipnoan terminals were lacking]; Holland et al. (2007) for Rhizodontidae; Ahlberg et al. (2008) for Elpistostegalia; and Carroll (2007) for Tetrapoda. The cladogram was built with the software Mesquite, version 2.75 (Maddison & Maddison, 2011). Names of terminals that have extant members are marked in black.
