Bouyancy model from Henderson at #PeerJ suggests #Spinosaurus model (based on Moroccan material) is top heavy and floats, but does not sink. Not good qualities for a diver/aquatic pursuit predator. Other large theropods better swimmers. https://t.co/qujWINV3xF #OA (Free PDF)
New data suggesting Spinosaurus was not a fully-aquatic adapted theropod. 3D modelling physics suggests it was not very competent in the water. https://t.co/ARz6eQmIhn via @thePeerJ
