FIGURE 1 in Tooth enamel microstructure in North American Phytosauria (Diapsida:Archosauriformes): Implications for biogeography and ecology of a Late Triassic clade of crocodylian-like predators

FIGURE 1. Geographic distribution and phylogenetic position of phytosaurs. 1A—Global distribution of phytosaur specimens from Middle and Late Triassic modified from Stocker and Butler (2013). Palaeomap from C. Scotese built into the Paleobiology Database for the Late Triassic (220 Ma) 1B—General cladogram of archosauromorphs that have been sampled for EM with the two possible positions of Phytosauria marked in red. Based on Heckert and Miller-Camp (2012) 1C—Locality map of specimens used in this study. North Carolina not to the same scale as western states. Locality numbers from NMMNH (western states) or NCSM (North Carolina).
