This is a very well-thought match, and hould render a good debate. I used to go with Tyrannosaurus rex, but I remain undecided now. Their advantages always cover disadvantages, and so on.

Welcome; For this match, as you requested it, we encourage our users to contribute to the thread. Anyway, thanks for sharing the picture Mecha, the femurs are nearly the same in axial length.

As well as having similar sized femurs, Tyrannosaurus and Tyrannotitan were also similar in overall length (~12 metres) so it seems that Tyrannotitan may of been closer to T. rex rather than other large Carcharodontosaurids in term of bulk.

Yes, Tyrannotitan chubutensis is supposedly very robust. Giganotosaurus carolinii (Coria & Salgado, 1995) specimen, MUCPv-Ch1, has a ~143cm femur, while MPEF-PV 1157 has a ~140cm femur. Considering both are in the Giganotosaurini, MUCPv-Ch1 has a femur that is ~2% larger, so based on a close relative, Tyrannotitan chubutensis should be ~2% smaller in axial length. Tyrannosaurus rex is apparently larger, but only by a little.

That is one shitty picture to use for T. rex lol

I think it is fine, but anyway, let's get back on topic. I did an analysis on Tyrannotitan chubutensis specimen, MPEF-PV 1157. The femur is ~2% smaller in axial length than the Giganotosaurus carolinii holotype's femur, MUCPv-Ch1. Novas et. al., (2013)'s cladogram puts both species as very related, so scaling them should be proper. My calculations gave me ~6.5 tonnes and ~12.1 metres, so I would say ~6-8 tonnes as a range and ~7.5 tonnes as an average.

t.rex wins, although tyrannotitan would not go down easily at all.

We have no acceptable number of any specie of allosauriods to suggest an average population size appart maybe Allosaurus and that size is changing all the time(since we have 60 specimens of Allosaurus).

I did never deny it wasn't speculation, and it is a possible number, despite the fact it is speculative. Furthermore, I never told anyone it was factual, so it's not really such a big deal.

Then what's the point of saying it though we have no evidence what so ever for any average Giganotosaurini

I said it as an opinion, not a fact. Is it a big deal, anyway?
