Abstract

Foot skeletons of small (young) hadrosaurid dinosaurs were compared with those of large (adult) hadrosaurids to assess the extent of pedal shape change during ontogeny. Foot skeletons of juvenile hadrosaurids were also compared with those of similar-sized adult, bipedal, non-hadrosaurian ornithischians to which the juvenile hadrosaurids were closer in size, to investigate the possibility that pedal shape change during hadrosaurid ontogeny would have been great enough for feet (and therefore footprints) of young hadrosaurids to have been more similar to those of small-bodied ornithischians than those of large adult hadrosaurids. Although possible allometric shape changes in hadrosaurid pedal proportions are detected, these are so subtle that the feet of young hadrosaurids are far more similar to those of adult hadrosaurs than those of small-bodied, non-hadrosaurid,ornithischians. Footprints made by conspecific hadrosaurids of different size and age are therefore likely to have been similar in shape, and footprints made by juvenile hadrosaurs are unlikely be misidentified as prints made by adults of smaller-bodied, more gracile, bipedal ornithischians.
