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 implicit question about these descriptions of the Spinosaurus: How were the relationships between spinosaurus and big crocodiles like sarcosuchus ? If the spinosaurus was quadrupedial on land, the coexistence between them would have been hard. Spinosaurus quadrupedial is supposed to be less fast, less "movable" than bipedial... And, on the other hand, despite being an aktive swimmer, under the water among these formidable opponents... I don't know.
Rather to imagine interactions with big theropods, spinosaurus had certainly to share his environment with various species of crocodiles. And I have some difficulties to imagine him as a top predator. Unless the crocs with which he coexisted were not so great and huge.
I believe there are always numerous unknown facts !
