Description
Here we go again, another speculative drawing.

As you may heard already, there are (there always were some anatomical issues by other experts) some problems around the Nizar Ibrahim Spinosaurus neotype. We know now the insanely strange proportions were caused by the "chimera effect". So the collected fossils contained Sigilmassasaurus fossils as well. Ibrahim was refering to the Spinosaurus B specimen which had a similar foot anatomia. But we know since that Spinosaurus B was a Sigilmassasaurus, and obviously that means the neotype contains pieces from Sigilmassasaurus as well.

So there were at least 2 Spinosaurids that existed in Kem Kem.

This also means that now once again the Scott Hartman version is the most valid one. But also the still fregmentary knowledge about this creature allow us to speculate widely.
Before the neotype, I used to have a speculation about Spino. I believed Spinosaurus was so massive compared to its other cousins, because even if it had almost the same piscivorous features as them, perhaps it was more terrestrial and prefered a little bit larger prey, like a Marabou (even if the fish in the rivers were also very big, but whatever). If we had only the bones of Marabou, we would thing it was as nice looking creature as a regular stork and probably feeding on small fish and lizards (while in real life they are feeding on even Flamingos, beside the fact that based on their bones they should need to be simple fish-eaters).
Dennonyx did a beautiful drawing based on my idea, but I think that pouch under the neck was a bit too much

Now, because there are problems around the neotype, I felt perhaps I should make this concept.

Although this creature is still not an "I'm going to kill EVERYTHING around me" awesombro monster, but still a little bit more terrestrial thing, beside fish-eating. It is roughly based on the Hartman version, but with a few changes. This one has a bit more massive legs. Not so fast, but allow to the animal to wander easily in the dry seasons. The sail is also as long as on the Hartman version but at the hip part it has a feature similar to that of Ichthyovenator, which is giving it a Basilisk lizard like appearance. The face and the neck are wrinkled like on a Marabou, which makes it a little bit savage looking beast. The tail is very long and muscular for the ballance.
You can also find my obvious clischés, such as the tail fluke, the skin-crest on the skull and the feathers which are replacing the too regular spikes.
But this is only one concept from the many versions that could easily be possible

Oh and also, because I have not seen yet any biological speculation about the appearance of a Spinosaurus genitalia, here is my version.
