Fig. 20. Phylogenetic relationships of Kryptops palaios gen. et sp. nov. and Eocarcharia dinops gen. et sp. nov., with arrows and dots signifying stem and node−based definitions, respectively. A. Strict consensus tree derived from parsimony analysis (Swofford 1998) of character data in Sereno et al. (2004) with the addition of Kryptops palaios (see text and Appendix 1). The two minimum length trees represent alternative resolutions among outgroups. Cladogram depicts relationships within Ceratosauria only, with the fragmentary genera Laevisuchus, Genusaurus, and Ilokelesia removed to reduce tree number and with multistate characters ordered. B. Strict consensus tree of carcharodontosaurid relationships showing the phylogenetic position of Eocarcharia dinops. C. Paleogeographic reconstruction of the earliest Late Cretaceous (Cenomanian, ca. 97 Ma) showing key land bridges (1–3) for intercontinental land connections (map based on Scotese 2001). A cross marks the location of the fossils in this report. Abbreviations: 1, Walvis Ridge, Rio Grande Rise; 2, Palmer Land Block, South Georgia Island Terrane; 3, Kerguelan Plateau, Gunnerus Ridge.
