based on 3D skeletal models. These estimates suggested that Patagotitan was 10% larger than Argentinosaurus. In 2019 Gregory S. Paul estimated Patagotitan at 31 m in length and 50 - 55 t in weight using volumetric models. This made it smaller than Argentinosaurus, which he estimated at over 35 m in length and 65 - 75 t in weight. In 2020, Campione and Evans yielded a body mass estimate of approximately 55.7 t. In 2020, Otero and Carballido published a lower mean
