Rex Fan 684
MemberCompsognathusOct-14-2013 4:07 PMSo, why is the specimen known as Thomas the T-rex so important to the size of Tyrannosaurus rex? For one thing, Thomas the T-rex is about 34 ft long and 7,000-8,000 lbs at 17 years of age. This length and weight are close to what many say an adult Rex would average. However, at 17, Thomas still has a full year of rapid growth yet to come. Since T-rex put on nearly 10 lbs a day during this growth, Thomas would have gained over 3,650 pounds. So, at age 18, he would be 10,650-11,650 lbs. Probably would have been about 36-38 ft in length. That's comparable to what they say an adult Rex would average. But, Thomas would have had about 12 years of life before he died at about age 30. Tyrannosaurus rex grew throughout it's life. During those 12 years or so, Thomas probably could have put on over 2,000 lbs at least, probably more. With that, he would at least be over 13,650-14,650 lbs by the time he died with a length of over 40 ft. That nearly rivals Sue in size! Seems to me the average Rex was actually 40-43 ft in length and 13,000-15,000 lbs by the time it died. With some being bigger than the average(possibly C. Rex and F. Rex), it's max size would be considerably higher. Approaching over 45 ft in length and 16,000-17,000 lbs or more. Just a thought about T-rex size and growth.
*Size estimations for estimated max adult size based on a combination of my theories and estimates, plus the estimates gathered from Thomas the T-rex and other Tyrannosaurus specimens.

MemberCompsognathusOct-14-2013 4:14 PMIndeed. One step closer to proving our theories about T-rex size DinoSteve. One step closer.

MemberCompsognathusOct-14-2013 5:28 PMThanks. I thought so too.

MemberCompsognathusOct-14-2013 5:52 PMYes, but the growth slowed to what was almost a halt around that age. Perhaps he was like me: a big teenager that would have grown very little after age 18. I was. 6'0 at age 14 but I only grew a couple more inches by 20 and at 22 I'm sure I'm done growing.
Sue is the one of oldest at 30 and most would average around 25 as an old adult so I can see Thomas growing to Sue size, but not into a 45 foot monster.
You can't argue evidence, and evidence indicates that out of 45+ specimens the mean size was 35-38 feet, though a considerable amount are 39. Sue is the longest at 40 feet and the heaviest as well, so how could they average 40-43 feet when only around less than 10% of known specimens top 39 feet and only one or two top 40 feet, still being below 43?

MemberCompsognathusOct-14-2013 5:58 PMHmmm... I think dinosaurs were growing like modern reptiles: the more you eat, the more you grow. So maybe him could has had a chance growing 43ft

MemberCompsognathusOct-14-2013 6:41 PMDinoFights, I never said Thomas could have reached 45 ft. I said 40 ft. With so many Rexes approaching the 40-43 ft range, I can't help but think the max size was obviously higher(45+ft).

MemberCompsognathusOct-14-2013 6:48 PMBy so many approaching 40, I'm assuming you mean one in ten adult specimens. None except for Sue and one other even get close to 43, and none hit that mark unless you give it liberal spine extensions.

MemberCompsognathusOct-14-2013 7:24 PMHere's a list of specimens that are about 40 ft or more....
The Holotype- 11.9 meters(39 ft)
AMNH 5027- 12 meters(41 ft)
Thomas- 12 meters(40 ft)*
Devil Rex- 11.6 meters(38 ft)
Sue- 12-13 meters(40-43 ft)**
Stan- 12 meters(40.1 ft)
Scotty- 12 meters(40 ft)
Samson- 11.9 meters(39 ft)
Possible Tyrannosaurus' rivaling Sue-
C. Rex- 13-14 meters(43-45 ft)
F. Rex- 12-13 meters(40-43 ft)
*Projected adult size for Thomas
** Depends on your estimates

MemberTyrannosaurus RexOct-14-2013 8:03 PMI didn't realize there were that many Rexes that big. I see 45 feet as a maximum for Rex. Average of 38-40 feet, but max of 45 in my opinion.

MemberCompsognathusOct-14-2013 8:05 PMThat's why I say the average is 40-43 ft. There are many specimens in that range. I usually say 45-50 ft as the max, so I agree with ya there.

MemberTyrannosaurus RexOct-14-2013 8:09 PMThat sounds reasonable. We agree on a lot of things Rex related.

MemberCompsognathusOct-14-2013 8:14 PMTrue.
PS- DinoFights, Sue was 28 when she died. Just a minor detail.

MemberTyrannosaurus RexOct-14-2013 8:16 PMThat's pretty good for a Rex, seeing as to how dangerous the late Cretaceous was for anything, even the apex predator.

MemberCompsognathusOct-15-2013 1:56 AMI thought Stan was 39 feet?
Anyway, yeah, but F. Rex and C. Rex appear to be carcharodontosaurids judging by photographs that recently surfaced.

MemberCompsognathusOct-15-2013 3:09 PMNope, Stan was a little over 40 ft.
Anyways, one or two pictures does not mean it's true. Going by pics can be dangerous(Horror Mouth and company for example). They've been considered Tyrannosaurus' for many years now. Suddenly, their validity as such is questionable? Seems strange to me.

MemberCompsognathusOct-15-2013 6:06 PMYou know rex fan, C. Rex and F. Rex could be a different, but similar species of tyrannosaur. They have that with Tarbosaurus and Z-tyrannus, so I'm wondering if that are different tyrannosaurs. Also, if Thomas was a teenager, and around 17, I think he could have gotten to about 41 feet by the time he's 18, at least. And given another twelve years, I bet your looking at a tyrannosaur at least 44 feet long, which is a both what my max estimate for them is.
Hi
Rex Fan 684
MemberCompsognathusOct-15-2013 8:34 PMKeep in mind he was only 34 ft at 17. But Thomas's projected adult size is debatable simply because it's estimates.
As far as C. Rex and F. Rex go, that's possible. However, as long as their genus remains Tyrannosaurus, then their sizes still increase the overall size for Tyrannosaurus as a whole. If that makes sense.
