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

Length
There are sources for theropods, like Spinosaurus, which was originally 18m, now revised to 15m. For Giganotosaurus, it was somewhere between 12.2 and 14m. 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 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
The first one is T. rex. I think the 18.5t estimate is really, really high but I don't think 20.9 for Spinosaurus, 14 for Giganotosaurus and 15.1 for Carcharodontosaurus is high. 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. 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.

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