Mad, When did the world acquire the strong gravity we have today???? The Dinosaurs were too huge for their bones (which were not steel) and muscles to hold them up. In S. America they cut a 200 ton stone from the solid rock and moved it over 200 miles over mountains terrain to top of the mountain. We have Stone Henge, the pyramids and endless other things. The gravity must have been very weak during the early billion years. Bill Stott (A real mad amateur scientist).
