Abstract
There is great interest in calculating accurate values for Earth’s palaeogravity. One fundamental technique to quantify palaeogravity is to compute weight against mass estimates of ancient animals. This technique is applied to the theropod dinosaur Megalosaurus bucklandii BMNH 31806 specimen. The results indicate a tentative palaeogravity of 0.51g ± 20% for 167 Ma.

Keep up the good work. Either the accepted methods for calculating animal weight are entirely wrong, or else you've made a great case for reduced gravity in the Mesozoic. Either way, mainstream scientists cannot ignore your results. One test that you might try would be to apply the accepted weight-estimation methods to modern bipeds that we know live in 1g, such as ostriches, to see if the methods come up with the right weight, i.e. a weight that we can actually measure. Coelophysis from the Upper Triassic, which you've already analyzed, was approximately the same size and mass as an ostrich.
