Stan 'n Sue comparison



With Stan and Sue now overhauled, I decided it was time to dust off the idea of comparing T. rex specimens. Eventually I'll update all of them (and add some new ones in), but for the next month or two this will have to suffice. Thanks to better scaling I can corroborate the femoral length of both specimens as published in Hutchinson et al's 2011 paper on computational analysis of tyrannosaur limb and body dimensions, as well as the overall length of FMNH PR2081 (Sue).

On the other hand I am unable to replicate the length estimate they provide for BHI 3033 (Stan). Stan's skeletal, as restored here, has a length of 11.28 meters, half a meter shorter than the 11.78 of the scanned mount. The discrepancy seems to stem from how long the reconstructed distal caudals are in the mount, as well as some very odd spacing in the scan (i.e. the mount) between the neck and skull. Otherwise the individual elements match up quite well between the scan and my reconstruction (which is good, because scan data rarely suffers from scaling errors).

What length have you restored FMNH PR 2081’s skull here? I know restorations of the uncrushed skull vary from 144 to 152 cm.
