FIGURE 5. Distribution of p3 patterns (PR0-PR2 sensu Čermák et al., 2015) in Eurasian species of Trischizolagus during the late Miocene-early late Pliocene (MN13-16). In T. dumitrescuae, black symbols represent particular localities bearing at least four p3 specimens, grey symbols are mean values for particular MN zones. Data taken from Radulesco and Samson (1967, 1995), de Bruijn et al. (1970), Janvier and Montenat (1971), Topachevsky (1980, 1987), Melik-Adamyan (1986), Cai (1989), Averianov and Tesakov (1997), Qiu and Storch (2000), Popov (2004).
