FIGURE 10 in New material of Alierasaurus ronchii (Synapsida, Caseidae) from the Permian of Sardinia (Italy), and its phylogenetic affinities
FIGURE 10. Cladograms obtained by including the basal caseid Eocasea martini (in green) in the cladistic analysis. Strict reduced consensus of three equally parsimonious trees with basal Caseasauria (in blue) not resolved (1); E. martini falling more basal then Eothyris could be external to Caseidae (2); E. martini as sister taxon of Eothyris, thus representing an eothyridid (3); E. martini represents the most basal caseid as suggested by Reisz and Fröbisch (2014) (4).
