Palaeogravity calculations based on
weight and mass estimates of four
Tyrannosaurus rex specimens

by

Stephen W. Hurrell



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 four specimens of Tyrannosaurus rex, representing some of the most complete theropod dinosaur skeletons known.  For the Tyrannosaurus rex specimens "Carnegie" CMNH 9380, “Wankel rex” MOR 555, "Stan" BHI 3033 and "Sue" FMNH PR 2081, the results indicate that a palaeogravity of 0.67g, 0.66g, 0.61g, and 0.64g ± 20% respectively are reliable estimates for 67 Ma.
