It is one of the biggest dinosaur yet found. == Habit and diet == Sauroposeidon lived in what was then a [[river delta]] flowing into a bay rather the [[Bay of Mexico]] is today. It was a [[plant]]-eater that probably ate from the tops of trees, probably mainly [[Conifer|conifers]], and [[Arecaceae|palms]]. == Estimations == Estimates of ''Sauroposeidon'''s size are based on a comparison between the four ''Sauroposeidon'' vertebrae and the vertebrae of the HM SII specimen of ''[[Giraffatitan]]'' in the [[Natural History Museum, Berlin|Humboldt Museum]] in [[Berlin]]. The HM SII is the most complete [[brachiosaur]] known. Comparisons to the other relatives of ''Sauroposeidon'' are difficult due to limited remains.<ref name=Wedeletal2000b> Wedel, Mathew J; Cifelli R.L. and Sanders R..K. 2000.

This is based on the assumption that the rest of the neck has the same proportions as ''Giraffatitan'', which is a reasonably good conjecture.<ref name=Wedeletal2000b/> ''Sauroposeidon'' was probably able to raise its head {{convert|17|m|ft|abbr=on}} above the ground, which is as high as a six-story building.
