Re: Sauropods in wet versus dry environments... a tip of the hat to some past artists (Was Re. Lost Worlds)

Indeed. Because, one mustn't forget that theropod footprints occur at some
of these localities as well. I'd imagine they wouldn't be highly aquatic,
just happened to be traveling across an area that happened to be good for
footprint preservation. Either extrapolate paleobiology for the whole
ichnofauna based on the substrate, or...do something else...
