Well, that is hardly the same metod that puts the largest T. rex at 9,5t. if the Giganotosaurus holotype is about the same weight as an average T. rex, half a ton heavier at maximum is easily possible given MUCPv-95 is 8% larger in linear terms. And 13,8t is BS, just like 9,5t T. rex If Acrocanthosaurus at 12m was ~6t, a Giganotosaurus at 13-14m would be 7,6-9,5t. Assuming an average T. rex was ~6,5t at 11,5-12m (which is the range it is probably in) Sue would have to be 7-8t As said, imo both are probably a bit much, in T. rex case I recall what Hartman, Brochu and Paul state, in the case of Giganotosaurus, the neural spines are not as pronounced as in Acrocanthosaurus. |

But it was said, "at least". The minimum would be ignoring the paratype. |

Oh yes, then it is BS (and its not a paratype, it was described in a different paper than the holotype), but minimum should be taken with a grain of salt considering it would be a comparison of the smallest Giganotosaurus and the largest T. rex. |

I too got that wrong for over a year. It seems there is no term for an ordinary referred specimen, so I have finally started to use MUCPv-95 |

Well If you can direct me to a source indicating some degree of parity of weight I'll make it. Comments like "similar in size"are too vague especially on Wikipedia.

if the original description written by two of the worlds leading palaeontologists is not enough for you, I don't really know what source could convince you, but if you will have a look at this: http://archosaur.us/theropoddatabase/Carnosauria.htm#Mapusaurusroseae I don't really think I'll have to repeat all the quotes and figures from the description paper, but keep in mind wikipedia was absolutely enough for you to deduce, erraneously, that Mapusaurus was only 10m and 3t, so I think it would be appropriate to believe what the authors state. Also, I must note for a femur only 1 cm shorter than that of the largest known Tyrannosaurus rex, 10m and 3t is a very conservative estimate. If you want some scaling based on these conservative figure, fine, here you go: assume Mapusaurus was 110% the dimensions of the giganotosaurus holotype (12,2-13m), we can deduce it was at least 2% longer in linear terms than the largest known Giganotosaurus, or 13,4 (vs 13,2) to 14,3 (vs 14) metres. Scaled up from the 10,2m/3t (regardless of whether that figure is really correct for the given specimen) we get 6,8-8,2t. This almost exactly corrleates with figures for Giganotosaurus, in fact 8,2t is the weight estimated for MUCPv-95 by Mazetta in 2004. Convinced? Mapusaurus is the same size as Giganotosaurus, if not slighly bigger, and probably dimensionally larger. |

Just based on similar bone measurements - not necessarily . What I wanted was the best weight estimates from reseachers for the two species please (preferably with a link) That's all you had to post.
