Hi readers, I just want to show everyone that the estimates that I disagree with about theropods.

Length edit

There are sources for theropods, like Spinosaurus, which was originally 18m, [1]now revised to 15m. [2] For Giganotosaurus, it was somewhere between 12.2 and 14m. [3][4]In this subpage, I will talk about the estimates I don't agree. First, I think the 14m for Giganotosaurus and the 13m for Tyrannotitan is too large. But they come from a published source[4] so we have no good reason to remove them since there isn't a peer-reviewed scientific source claiming those estimates are wrong. I agree a bit with Tyrannotitan, because I did calculated 13m using its 141cm femur. I also think Saurophaganax and Chilantaisaurus's lower range is too high but what I could find is only a website which doesn't count as a publish source. For T. rex, I think it shall have a lower range of 11m based on small specimens. I also think Deltadromeus was 8.1-13.3m but it can't be on Wikipedia articles because what I did was original research.

Mass edit

The first one is T. rex. I think the 18.5t [5] estimate is really, really high but I don't think 20.9 for Spinosaurus, 14 for Giganotosaurus and 15.1 for Carcharodontosaurus is high. [6] I don't even think the concept of "Carnosaurs are more lightly built than Tyrannosaurs" by Dinoguy2 is correct. I think carnosaurs are more solidly built. I don't agree with the concept at all. However, 18.5t comes from a published source and we have no good reason to mistrust it, just like 35m and 75t for Mamenchisaurus.[4] I think there are lower estimates for Giganotosaurus and Carcharodontosaurus but they both come from that dml website in the previous section. I think Oxalaia was heavier than Acrocanthosaurus and that Tyrannotitan shall have a lower range but no sources for that.

Commons edit

My opinion about Giganotosaurus and Tyrannotitan's numbers rose. Did not talk about Chilantaisaurus - Could not find any high estimates but only 11-13m.
