When linear dimensions are doubled the cross section increases four fold and the weight increases eight fold.(The square and cube of the increase ratio.) The legs of elephants are columnar of necessity to carry its’ weight of around 6/7 tonnes. The legs of elephants scale at about one seventh of their shoulder height. So a dinosaur of the same weight would not be able to supports itself on two legs especially of the style of Tyrannosaurus Rex.

It seems to me that the conclusion that birds developed from dinosaurs raises the question why did light bone structure develop it makes sense that it was to cope with size. If we take birds as the comparison and look at the proportions of the swan, it has a body weight of 13.5kg and a shoulder height of around 0.6M. The dinosaur of comparative shape to the swan is Tyranosaurus Rex. Shoulder height 3.5M. 5.8 times the height of a swan, so if it was the same structure the weight would be 5.8³ = 195 times the weight ( 195 * 13.5kg = 2.6 tonne)lighter than the currently accepted 7.2 tonnes. The swans leg is around 2cm diameter. Using the same logic the Tyrannosaurus leg diameter would be √195 = 14 times that. This would make the T Rex leg to be 28cm diameter. Which makes the ratio of height to leg diameter = 12.5. ( This appears about right.) Dbeck20ntlworld(talk) 16:10, 9 October 2011 (UTC)
