Fig. 7 in Diversity of diapsid fifth metatarsals from the Lower Triassic karst deposits of Czatkowice, southern Poland -functional and phylogenetic implications

Fig. 7. Schematic relations between distal tarsals and metatarsals in Archosauriformes. A. Erythrosuchus, Erythrosuchidae, Early Triassic, Africa (after Gower 1996). B. Euparkeria, Euparkeriidae, Middle Triassic South Africa after Ewer 1965). C. Riojasuchus, Crurotarsi, Late Triassic South America after Sereno 1991). D. Rhamphorhynchus, Pterosauria, Late Jurassic, Europe, Africa (after Wellnhofer 1991). E. Pteranodon, Pterosauria, Late Cretaceous, North America (after Bennett 2001). F. Scleromochlus, Ornithodira, Late Triassic, England (after Benton 1999). G. Marasuchus, Dinosauriformes, Middle Triassic, South America (after Sereno and Arcucci 1994). Dorsal (A, B) and plantar (C, G) views. dTIV, MttIV and MttV shaded in grey. 3, saurian synapomorphy: neckless hooked MttV; 5, ornithodiran synapomorphy: MttV straight, reduced in size and importance. Not to scale.
