Recently there has been a study on Spinosaurus legs that shows that he couldn’t support the weight he has on such short legs and that legs must have been 4 times bigger in order for him to function properly. So the small legs were probably from totally different species mixed with Spino skeleton or a juvenile.
Finally he is back to normal.
I sure hope he had normal sized legs. The JP3 spino was a godless killing machine. The current model with tiny legs looks terrible at hunting both in and out of water.
