There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

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.
