Protosuchus missed a lot of the before-the-dinosaurs documentaries associated with the Walking With series. There is very little video evidence of Protosuchus models in use in any situation actually. That which does exist is a somewhat loose interpretation of Protosuchus walking through an illustrated forest. Considering the limbs of Protosuchus it is not too unrealistic to compare the high walk of crocodiles with this animal. Be aware, though, that this is in no way completely and 100% analogous. We do not want to start a fight about how they are not crocodiles and are only vaguely similar.
