How to know the weight of a dinosaur? Find a big ship, draw a line on side of the ship, and load it with heavy objects? If it weren’t for the fact that the dinosaurs have already been extinct, this would be a good idea to measure.
Scientists have conceived two methods with no need for physical objects. Luckily, according to the research published yesterday in the famous Biological Review, both could produce very similar results.
Dr. Nicolás Campione, the lead author of the study, said that these findings would give scientists confidence that they could explore the biological information of prehistoric behemoths with higher precision.

Dr. Campione, a member of the Paleontology Research Center at University of New England, said: “Body size, especially weight, determines almost all aspects of animal life, including diet, reproduction and exercise. If the accuracy of weight estimation could be confirmed, there would be a solid foundation for tracing and understanding their life history.”
Dinosaurs once enjoyed the absolute hegemony on earth, but now only bone fossils remained. In order to accurately estimate their bone mass, scientists have painstakingly studied for a century.
The research team led by Dr. Campione edited and reviewed the data set of dinosaur weight, dating back to 1905, to assess whether different methods could make the information clearer or more complicated.
