Which North American sauropod is noted as being extremely long but typically estimated to be lighter than Patagotitan?

Answer

Supersaurus

The giant titanosaur group is small, making direct comparisons useful for contextualizing the scale of Patagotitan. When comparing Patagotitan's immense body mass accumulation against other giants, the Supersaurus is brought up as a counterpoint. While the North American Supersaurus possessed extreme length, its estimated total mass generally falls short of the massive weight calculated for Patagotitan. This distinction emphasizes that Patagotitan excels particularly in the dimension of body mass rather than solely maximum linear dimension.
