Figure Lengend Snippet: How differential depth of manus and pes may affect trackway configurations. Note manus only and manus dominated trackways are common in the sauropod track record (left). The possibility of a pes deeper than manus scenario to explain apparent evidence of a bipedal crocodilian (right) is considered a possibly, but highly unlikely. See text for details.

Figure Lengend Snippet: Left to right: Comparison of trackways of modern Crocodylus acutus , Batrachopus grandis ichnosp. nov., Mehliella jeffersonensis (with tail trace) and the pterosaur trackway Haenamichnus uhangriensis (right) , showing difference in trackway width. Note that B. grandis ichnosp. nov. trackway indicates a biped and that the trackway is narrow with inner trackway width negative.
