An old T. rex drawing, size comparisons etc...

[robban]

Here's a T. rex skeleton model I've built. It's a poor copy of Kaiyodo's 1/20 T. rex skeleton. I've made alot of modifications to it, most of them to the skull. It's not ready yet though.



Here is an old drawing of T. rex I made many years ago.

Here's a size comparison I've made in photoshop.

Hope you all will like them!

Nice drawings! even with the pronated hands the Tyrannosaur looks very good. The other theropods are cool too.

The size chart looks fine and updated ( Probably the Spino should be a little bulkier...but either way looks good) ...what´s the point of having 2 specimen of T. rexes btw? maybe other Tyrannosaur like Tarbosaurus would be more interesting

Thanks arioch!

Well, the topic of sizes is usually very intense on some forums. We know how large Sue was, as her skeleton is almost complete. Very few remains have been found of the Spinosaurus yet many people are dead certain it was 17-18 meters long. So, the MOR 008 skull is just a skull, but it is almost intact, and it is larger than Sue's skull so I figured what the heck. How large could the MOR 008 rex have been? I just scaled up the body to fit with the larger head. Is it correct? Who knows? Was Spinosaurus 18 meters long? Who knows?

I feel like people usually make too big of a deal about big theropod sizes. It doesn´really matter if Spino was 18 or just 14 meters long, it still would be heavier than any other theropod (thanks mainly to the hump mass and bone density) and by any means a big game hunter. Is a big scaly heron anyway. A slighlty larger Tyrannosaur would be equally deadly, although slower. There is no point in getting so big if you can´t catch your prey! ;D

The Giganotosaurus should be larger. It had a 6' long skull versus about 5.2' for the largest TRex. Ergo the Giga skull (and the entire animal) ought to be larger. Not longer, but definitely larger.

[robban]

But the skull of the Giganotosaurus in the drawing is 2 meters long, or 6ft. The total length of the animal in the drawing is 13.2 meters.

[arioch]

I think the Giga is ok. Carcharodontosaurs skull are proportionally bigger than tyrannosaurs. And it would be overall a bit longer but no heavier or more robust.

[simon]

Yeah ... Trex skull would be more robust ... I wish Horner would release the measurements for the partial "C-Rex" skeleton, particularly the head (I believe that most of the upper part is preserved) as it appears to have been 13.6 - 14.1 meters long and about 10% larger than 'Sue' ...
