T.rex was bigger (=heavier) than Spinosaurus

That's great! Other evidences for my and RexFan's theory. Thanks for the article link Gigadino! ;)

Also, 4,4 t for Spino, it should be a reasonable minimums weight.

OFF TOPIC- Gigadino, sei per caso italiano? :)

Sì, sono italiano ;)

Ne ero sicuro, haha. Anche io lo sono, pero adesso vivo in Romania. Ho vissuto in Italia per 12 anni comunque... a Milano.

Comunque, grandiose notizie!

And Spyrannosaurus called me insane for believing this! This is a great find. I've always felt 4-7 tons was a reasonable range for Spinosaurus.

He called everyone but Gigadino and S-Rex insane, not to mention got banned for it. This is awesome, and 4.4 ton area, that's freaking light. Some theories have been proven right, thank you Gigadino.

Good point MrHappy. Either way, I'm really excited right now.

This is exciting news. Not sure if S-Rex or any other members of team Spino will like this (the Rex-Haters especially).

Well, like it or not, it's a very accurate, very possible theory/study. And I'm not just saying that cause it coincides with my theory. 

True. Does this make Rex the undisputed King again? Of course, Giga and Charcar are a side note, but besides them.

It certainly helps T-rex out. Giga and Carchar are likely lighter too(more slender), so T-rex is probably heavier than them too.

Exactly. The King is back, and bigger than ever (that would be a cool line for Jurassic World, Eh?)

Haha, it would be good.

Everybody knows me, im not gonna let go of spinosaurus being bigger in every way than trex, especially wieght. Those are that sites opinions, not facts and never will be until absolute proof.

I was waiting to see what you'd say S-Rex. As has been said in EVERY Rex vs Spino, everyone has opinions, and that's fine that you think Spino is bigger than Rex in EVERY way (bite force excluded, right?). Our opinion appears to have SOME scientific evidence however, but as you said, we may never know (never say never, have you heard about the T-Rex soft tissue discovery, we're that much closer to JP IRL).

Hey, I'm not gonnna tell people what to believe. But I will say the support for the theory that T-rex remains the largest land predator is building. In fact, there may be more evidince and support for T-rex being heavier than Spinosaurus than vice versa at this point.

I think that's impossible. Maybe Spinosaurus was 55% heavier than Tyrannosaurus, but not 55% of its size. If you looked at reconstructions of their largest specimens side by side (Sue and MSNM V4047) and actually measured out the surface area, you would see that Spinosaurus is much larger than Tyrannosaurus. There is no way around that. Sue may have marginally outweighed the first Spinosaurus specimen (14 meters) but could not outweigh MSNM V4047 (16-18 meters) assuming it had the same build as Suchomimus, Baryonyx, and other spinosaurs. If anything, it would have a thicker build to support the greater weight.

As said before, everyone has opinions, so I respect yours so long as you respect mine.

Also, welcome back Philosiraptor, haven't seen you in a while.

We may never know how much was big Spinosaurus. Spinosaurus was likely longer (maybe around to fifty feet), though T.rex, according to Cau, was heavier. Hell, I think too that 4,4 t it's feak light, I think that 1-2 tonnes more than that is more likely, but hey, it's just me.

Not just you Gigadino, there are at least two other members (me among) that share this very thought.. 4,4 t is certainlly a minimum. Also, Spino is too fragmentary for a precise size to be estimated.

But, hey, this is no Rex vs. Spino. Is about Rex being heavier than initially thought by people.
