Diagnosis
ReferenceDiagnosis
V. M. Arbour et al. 2024Ruopodosaurus trackways include a pentadactyl manus and tridactyl pes, and can be differentiated from other putative tridactyl thyreophoran ichnotaxa by the outward (rather than inward) rotation of the pes tracks from the midline, and the rounded or bilobed heel. Pes tracks have robust digits ending in blunt triangular or U-shaped toe tips, and are weakly mesaxonic. Divarication between digits II and IV between 60–80°. Manus tracks wider than long and crescentic, with short, blunt digits. Manus tracks are rotated outward relative to trackway midline. Trackways are narrow gauge (pes track ratio is 50% or greater).
