 EDIT: Please note that most of this comparison is not really accurate and that I didn´t have very good material available at the time, see my blog for some newer skull restorations.
Posted Image
Allosaurus and Saurophaganax: extrapolated from smaller individuals to 12 and 15m respectively (call that speculation on the Monster of Minden or those 90cm footprints if you don´t like the figure ;) )
Torvosaurus: Mateus et al, 2006 (fairly obvious)
Tyrannosaurus rex: this is Sues measurement (154cm is mandible lenght measured along the curve a measurement mentioned by Holtz that I don´t know what it refers to and how it fits Brochus). there are rumoured bigger skulls, but there is no really reliable site stating so. Of course that toebone could belong to something with a significantly larger skull, and a partial maxilla was estimated at 4cm longer than sues in some blog comment I read (EDIT: and was in fact some centimetres shorter, isn´t that funny? T. rex literally forces some people to make up BS. not that I hadn´t also spread badly researched informations from time to time, but in no creature so far I saw so many specimens made larger than they where.)
Spinosaurus aegyptiacus: Dal Sasso et al, 2005
Carcharodontosaurus saharicus: Neotype, Sereno et al 1996
Giganotosaurus carolinii: Coria & Calvo, 1998 (EDIT: probably too elongated)
Mapusaurus rosae: from Greys scale. This is the only skull size estimate I have ever read for this animal, and it matches up well with both the fibula and some articles and experts describing it as larger than T. rex´s, as well as a reconstructed skull I found later.

Scale bar=1m, one grid segment is 20cm

 African wolf & golden jackal

Note that African wolf and jackal sizes do overlap, so really, the distinguishing features are the head, proportions and expressive behaviour.

click the image for a larger version
Apatosaurus = 28 meters, 46.363-53.387 tonnes
Tyrannosaurus = 12.4 meters, 6 tonnes

And people still believe that T. rex is the king, it's not a king...

Does anyone here know Cotylorhynchus? It's the largest non-mammal synapsid that ever lived

 I know it, but i´m not so shure whether is larger (=heavier) than moschops, elephantosaurus or that unnamed dicynodont.

Stop hating.
I know it´s annoying to read that in every post, but T. rex not being the king is a fact, not hating. i can also understant how he is annoyed by so many people considering it superior to other dinosaurs just because of it´s name and how famous it is.

If your Comparison is accurate, Tyrannosaurus would easily bite the nick and rip a small part of it, and this would make the Sauropod die.
