Fig. 1 in Dyrosaurid (Crocodyliformes: Mesoeucrocodylia) Fossils from the Upper Cretaceous and Paleogene of Mali: Implications for Phylogeny and Survivorship across the K/T Boundary

Fig. 1. Alternative hypotheses explaining the phylogenetic relationships of dyrosaurids. A, ''manual cladogram'', not based on a cladistic data matrix, hypothesized by Buffetaut (1978b). B, cladogram presented by Jouve (2005), based on cladistic analysis of 12 characters. C, cladogram presented by Jouve et al (2005b), based on cladistic analysis of 30 characters. Note basal position of Phosphatosaurus and highly nested position of Hyposaurus common to all hypotheses.
