This is specimen FMNH PR2081, the largest, most complete, most awesome, most hyperbole-filled specimen of Tyrannosaurus on the planet (the known universe, really).

In all seriousness it's a very nice specimen, but in many ways too much has already been written about it (especially on the interwebs). Still, such a lovely and quite complete specimen needs to be restored, so here it is.

Edit: A perceptive question by bLAZZE92 led me to re-evaluate the skeletal reconstruction again, and I was able to leverage newer data to catch some scaling errors I perpetuated from the original monograph. Thankfully the nips and tucks were much smaller than the recent Stan update, but the legs are a bit shorter now (on the order of 4-7%, depending on the element). Some even more minor adjustments were made to the presacral column. I now have much better references for the skull than I did back in 2006, so I redrew it from scratch; the changes aren't dramatic there either, but it does look a bit different.

Perhaps most pleasantly out of this whole process, I got a better constrained scale bar (since I was able to eliminate the scaling inconsistencies inherent in the original publication). The result is an animal that measures almost exactly 12.3 meters (12.32 by my hand), which (for those of you who are metric-impaired) gives us a T. rex specimen that actually reaches 40 feet.

I saw the latest version of this one. Shouldn't have the gastralia needed an increase in size/length based on how big the gastralia are on the mounted skeleton? Franoys and randomdinos did increase the size of the gastralia in their skeletals based on it, you can check them if you're interested.

 Fabulous work you've got there, and its' the single best T.rex reconstruction I've ever seen so far. The proportions are ideal for what I think of the animal, especially the ratio of the legs to that of the torso and the head. I also use this Picture as a reference for all my T.rex drawings. Keep it up. The ceratosaurus is equally awesome

Hi Scott! Please respond to what Franoys and bricksmashtv found! I'm very intrigued about this, like Franoys, too!

All the dinosaur art work in this gallery is outstanding.  I downloaded Sue the T.rex and we plan to use in an educational poster for elementary and high school students.  Well done Scott!

Hi Scott. I've been thinking on how your Sue restoration hindlimbs look a bit short when compared to the mount and the mount replicas. Your Sue also seems to be within centimeters in hip height to all your other restored Tyrannosaurus while Hutchinson et al states Sue's legs to be 25 cm longer than the other specimens (all the other specimens being very close to each other). Did you measure the hindlimb bones yourself? Or are the leg proportions purely based of Hutchinson et al "A Computational Analysis of Limb and Body Dimensions  nTyrannosaurus rex with Implications for Locomotion, Ontogeny, and Growth"?

Because if they are, they gave a 3,3 meters stimate for the hindlimbs  journals.plos.org/plosone/arti… while in your restoration the hindlimbs seem to be 3,12 meters in length (I measured the skeletal with gimp, it yielded 1,31m for the femur, 1,20 for the tibia and 0,61 for the Tarsus+metatarsal lll). With a 3,3 meters leg length, then Sue would be about 3,6 meters tall to the hips (in the same position as in your drawing) instead of the 3,45m tall she is now, and would be more coherent with the 25 cm difference in leg length between Sue and the other adult Rex specimens.

According to the measurements in the JVP monograph appendix (link here in case anyone needs it) the measurements are as follows (in cm obviously XD):

Femur: 132.1 (right); 130.8 (left)
Left tibia: 114.3 (without tarsus); 124.5 (with tarsus)
Metatarsal III: 67.1

so Scott's metatarsal III seems to be too short.

my bad here's the JVP monograph drive.google.com/file/d/0B8Yj0…

So, checking the anatomy really close it is something like this:

Using the measurements table:

Femur (1,32m)+ Tibia+ calcaneum+ astragalus (1,245)+ tarsal bone (0,03m)+ Metatarsal lll (0,671) = 3,266 meters.

While when measuring Scott's skeletal I get legs no longer than 3,12m.

Hutchinson et al got 3,3 m for the legs when Lidar scanning the mount.

Ibrahim et al is the only source that gets legs 3,13 m long, but they ignored the calcaneum+ astragalus for calculating the leg length.

Also Larramendi has got this exact same bone measurements for his Sue. So I believe this is pretty much settled. The legs are like 15-17 cm too short in this restoration.

Indeed so

It is like 16,3 cm shorter than it should be, considering I measured the metatarsal and the tarsus together. The leg length with the measurements you provided would be 3,26 m which is close to what hutchinson et al suggested.

Hi Scott. What are your thoughts on this? If you had the time to answer, I would be gratful since I'm intrigued about this. Grettings!

I've seen your dinosaur skeletals in the book Dinosaurs: How to Draw Thunder Lizards and Other Prehistoric Beasts

can i use this as a skeletal reference?

Sure thing.

How long is the skull at its greatest length? Also, can you show me the T. rex skeletal made by Kenneth Carpenter? I've never seen it, and I failed to find it on the web (Paleo-reptiles wrote he send it to you on Facebook).
