Well, they are both of course unusually complete skeletons, but the variation among the other specimens is in the parts that are preserved, not the parts that are not. If anything, the others would be even more different if they were more complete, since inevitably missing elements are restored based on, and hence the same as, the equivalent elements in other skeletons. Their tibiae are literally exactly the same length though. Yes I am quite aware of that. As for the ilium though, that one is frankly weird, it looks nothing like other T. rex ilia which all have that pronounced notch in the anterior ilium. When you look at the paper describing it, the ilium as figured in the composite in fig. 1B actually looks a lot more like what you would expect, and when you look at the most recent revision of randomdinos’ skeletal, you’ll see this has seemingly been accounted for now: www.deviantart.com/randomdinos/art/Tyrannosaurus-rex-skeletal-reconstructions--759469239Also, reptiles don’t have lumbar vertebrae  Well, the evidence for dimorphism in T. rex is still pretty sketchy, but that is a possibility. There isn’t really a big difference in the pelvic bone structure between sue and scotty though. There’s literally a bigger difference between the two ilia of sue than there is between sue’s well-preserved ilium and scotty. The ischia seem to vary a bit between all T. rex specimens, scotty is no exception. And the pubis looks very similar to sue’s. MOR 555’s pelvis, at least going by randomdinos’ skeletal, looks a lot more unusual than scotty’s. |

Someone I have been talking to recently whipped up this comparison between the African lion ( P.leo) and the American lion ( P. atrox).  |

Various large theropods vs Therizinosaurus (ignore the Spinosaurus btw) I think it best to avoid taking Wikipedia's size comparisons with anything more than a grain of salt as much as possible. |

I agree with Infinity blade especially with that comparison it is really outdated the newer ones on wiki are much better but still are not completely perfect.

Well other than the Spinosaurus, the dimensions of everything seemed right. But yeah, you do have a point |

Some big theropods and the African bush elephant Isn't the Mapusaurus somewhat undersized? From what I know, 12-12.5 meters and 7 tons is the average, while the max is 13.6 meters and 8.5 tons as per specimen MCF-PVPH-108.145 (pubic shaft fragment) NOTE: That is not MCF on the chart. It's undersized as the pubic shaft is 10 percent larger than the Giganotosaurus holotype |
