Figure 11 in Evolutionary morphology of the coelurosaurian arctometatarsus: descriptive, morphometric and phylogenetic approaches

Figure 11. Bayesian inference-derived phylogeny after matrix of Holtz (2000), showing distribution of the arctometatarsus and observed ligament correlates on theropod metatarsals. Posterior probabilities (in percent) are shown at each node. 'Arcto.' designates a complete arctometatarsus, while '(Arcto.)' indicates a variant of the morphology. Taxa with proximal intermetatarsal striations are highlighted in grey, and double asterisks signify distal ligament correlates. Phylogenetic bracketing (Witmer, 1995) indicates the presence of proximal intermetatarsal ligaments in taxa between Torvosaurus and Tyrannosauridae. This condition is interpreted as preceding the evolution of distal ligaments in the arctometatarsus. Outgroup comparison indicates broader distribution of proximal metatarsus ligaments in the Dinosauria (see text).Published as part of Snively, Eric, Russell, Anthony P. & Powell, G.
