...ANTHONY R. FIORILLO; RONALD S. TYKOSKI Abstract We report on a paired set of manus and pes tracks from the lower part of the Upper Cretaceous Cantwell Formation in Denali National Park, Alaska, USA. The tridactyl track is bi-lobed in the ‘heel' and the morphology allows attribution to a hadrosaurid...
