This used to be the predominant idea. It has been shown to be untenable
through several lines of evidence.
1. Semi-aquatic tetrapods have wide bodies and proportionally larger than
usual feet (like hippos). Sauropods have narrow bodies, and merely
elephant-sized feet.
2. Statistical analysis of the distribution of sauropod bones in the
Morrison shows they occur in a pattern more like a terrestrial animal
(elephants, for instance) than a pattern like semi-aquatic animals (like
hippos and the extinct aquatic rhino). [This is based on a comparison with
fossil mammal bones].
3. The Morrison formation turns put to have been a semi-arid habitat, with
few large lakes - and many of the lakes that were there were seasonal.
