Fig. 2 in Mitochondrial DNA sequences suggest unexpected phylogenetic position of Corso-Sardinian grass snakes (Natrix cetti) and do not support their species status, with notes on phylogeography and subspecies delineation of grass snakes

Fig. 2 Parsimony networks for haplotypes of Natrix natrix helvetica, N. n. lanzai, a N. n. helvetica x natrix hybrid (left) and Corso-Sardinian grass snakes (right) based on 3,806 bp of mtDNA (ND1, ND2, ND4, cyt b). The large symbol for N. n. helvetica indicates that this haplotype was found twice; small black circles, missing node haplotypes. Connections between haplotypes show number of mutation steps. Connection of haplotypes in left network enforced; 95% connection limit: 27 steps

Fig. 6 in Hypotheses on rostral shield evolution in fossorial lizards derived from the phylogenetic position of a new species of Paracontias (Squamata, Scincidae)

Fig. 6 Evolutionary origin of the rostral shield in Paracontias. Two hypotheses may explain genesis of the rostral shield; both involve the same first evolutionary step: fusion of the rostral with the supranasals and the postnasals. In the one step hypothesis, the rostral shield results from fusion of the first supralabial with the rostral scale. In the two step hypothesis, a rostral pseudo-shield constitutes an intermediate
