Ichnological evidence from the Ravenscar Group (Middle Jurassic) of
Yorkshire reveals a distinctive type of swimming track associated with
walking tracks of the ichnogenus Deltapodus. The morphology of the
prints suggests that both track types were made by the same type of
animal. Since Deltapodus is interpreted as having been made by a
stegosaur, the associated footprints suggest that stegosaurs could
swim. This has significant implications for their palaeobiology and
dispersal. The swimming prints are assigned to the ichnotaxon
Characichnos isp.
