Fig. 4 in A new large-bodied theropod dinosaur from the Middle Jurassic of Warwickshire, United Kingdom
Fig. 4. Simplified cladogram showing the alternative possible phylogenetic placements of Cruxicheros newmanorum based on analysis of the modified data set of Benson (2010). Fukuiraptor was not included in this scheme as it was recently demonstrated to be a derived allosauroid and not a basal neotetanuran (Benson et al. 2010). C. newmanorum was recovered as either a basal megalosauroid (A), a basal tetanuran (B) or a basal neotetanuran (C).

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.
