Giganotosaurus is one case, and looks like that website has 1.29 m for Scotty's femur length (Persons et al. 2019 reports 1.333 m). In mammal bones, the difference is a few millimeters at best. Perhaps the larger the bone, the more difference in measurement between two observers? For instance, measuring a hemimandible of a cat, the measurement is shorter if the hemimandible is rested on its lateral or buccal side, and longest if measured in its natural in situ position (resting at the inferior base).

A lot of it comes down to just bad descriptions and hearsay really. It took years and years to actually properly dig up Scotty because of its size and the specimens bones were deeply packed in thick iron-laden sandstone which took more than twenty years for the team to fully remove then excavate and assemble the majority of the skeleton properly then it was finally studied and its bones were measured this is much better than instead of people just going from pictures of the mounts and stuff like that. So much when it comes to dinosaurs on the internet is really outdated and often it never gets updated then people carry on using it as a source and the cycle continues just checking the theropod database shows this. Does not help either that good detailed descriptions take so long to be done then to go through the review process. Might take another 20 years until we get another good description for a big theropod dinosaur. Reply
