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.

Damn, they really were close to the ground.

Its like crocodile levels, I never knew that, documentaries always gave them longer legs

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

I'm with an non-profit organization Adventure-360 (Paleo X) where we travel to northeastern Montana to prospect for dinosaur fossils in the Hell Creek Formation every summer. We stay in a little town called Jordan. We take, adults (many are science teachers), families and high school students into the field (state and federal sections) to search for fossils. The high school students can earn college credit in paleontology. Our staff does include a Paleontologist.

The poster will be posted in our prep and presentation area with all bones will colored and labeled for identification and measurement with the respect to the fossils we find. I am planning to do posters on triceratops and hadrosaurs as these are the predominant fossils we find in this area. I plan on sending you a draft version. I just need to know how to properly credit you for your art.

My first draft is Stan the T.rex. I download it, but I had no information on it's origin. With some research and searching I finally ran down your site to check for copyright information.

I one question. How do I can I get access to the JPG files for Stan the t.rex, triceratops and hadrosaurs (and others) so I can properly spend my points?

For your information I have included our website for you to checkout. This will give good idea how we plan to use your dinosaur artwork.

Well done Scott and thanks! Gene

I've seen a LOT of different takes on Tyrannosaurus rex skeletons, let alone "Sue" skeleton recreations. Most resemble the Jurassic Park style tyrannos. Others don't get the proportions not quite right. This one is PERFECT! Using the official Sue stats compared to this image, you've got it exactly the right size. Well done!

The Tyrannosaur at the bottom portion of the image is great for size comparisons and for showing the completed specimen. The upper portion showing how much the specimen was actually found (and with the accompanying info) are very informative as well. I knew that Sue was 90% complete, but didn't know where the 10% missing were from.

This is awesome, the skull is great, the legs not that much, i love how the vertebras are done, the arm is very good, the tail is a little bit short, if it had more five or six vertebras is would be perfect, the legs are to short, if they were longer Sue, the 12,3 to 12,8 meters T-rex would have her head height of 4,2 meters but this as just 3,5 meters, but great work it's as robust as it should be I give a mass estimate of eight tones, the mass of Sue when alive, it's almost perfect.

I think the legs are the perfect size, only reason it appears shorter to you is maybe the pose of the drawn skeleton, a dynamic running pose with the head bent downwards, but if it was on an standing still pose with it's feet closer to each other and more extended legs i think it would reach 4 meters at the hips no problem.

To be fair....
the general proportions of the skeletal are perfect...
Dimensional inequality derived from the bones support in the cast mount.
Another thing:
Animals are in moviment fossils and skeletal no, so this skeletal and the one by hartman on skeletal drawing have a different height (little obviously) vause neck posture is different, and for the cast mount is the same (so the hips heigt is near 3.5m and the head reach 4 m)
"Sue" is not 100% complete so is imposssible to say certenly that it was 12.3 or 12.8, it was very huge and it's a prove for a near to 12.5 m T.rex.

Thanks for the comments, but I'm curious what are you basing your thoughts on the proportions on? I only ask because I'm _really sure_ the ones in the skeletal are correct. Past estimates (e.g. those floating around on the web) are based on older (and incorrect) measurements.

Books, wikipedia, another blogs.
DrScottHartman's avatar
Yeah - unfortunately those sources aren't always as reliable as we'd like. I'm quite confident in the proportions of this skeletal.

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!

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.

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.
Franoys's avatar
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
