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 Coelophysis bauri specimens AMNH 7223 and AMNH 2704. The results indicate that palaeogravity estimates of 0.44g ± 20% for the AMNH 7223 specimen and 0.42g ± 40% for the AMNH 2704 specimen are reliable estimates for 210 Ma.

From Facebook - Tony Lucas. A nice tight argument Stephen. Palaeontologist ignoring bone circumference calculations of weight is a case of discarding data that does not fit their hypothesis. Hardly compliant with the scientific method. Raises some scientific quality assurance issues.
I like the way that you pulled together all the available data to show that there are very few variables (volume / mass), that they are tightly constrained, and that the clear and simple implication is a much lower gravity.
