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
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.
