Another misconception, Spinosaurus as a quadruped is not exactly disproven. We don't have the forelimbs or the pectoral girdle. Compared to the 2014 model, in the 2020 model the center of gravity just slightly shifts backward given the now heavier tail. Therefore, they reconstructed it as a biped. I checked that supposed Spinosaurus arm again and it's probably a composite. So it seems unfortunately we still don't know much of the front half of Spinosaurus. It would take just a slightly heavier head, wider pectoral girdle, or some longer cervical spines to tip the 2020 model back to a quadrupedal position. I am not saying Spinosaurus was quadrupedal, but I am trying to illuminate this "disproven" misconception as most don't seem to understand the methods and the reason for the change. Reply
