Comment on Spinosaurus aegyptiacus All Yestered by Rodrigo-Vega
You realized that spinosaurus' snout was carefully examined right? Trunks like these (reptiles have few muscles on their faces so such strong and muscular trunk on the face of a reptilian creature should probably be already counted as an innacuracy). Muscle attachments leave distinctive scars on the bones and if spinosaurus had such muscles, such marks would have been found. But instead, croc like "snout holes" were found, which means that it could not have had any extrmely muscular structure on it's snout, or the sensors on the snout would be useless.
Spinosaurus had both thick and thin sail bones, but as we see in modern animals only thick sail bones can sustain a hump, while both think and thick ones can sustain a sail (and in humps the top of the "sail" bones looks rougher than the rest of the bones, something that is not seen in spinosaurus). Also spinosaurus lived on a very rich environment and if it was a warm blooded semi aquatic animal, no droughts could happen or it would starve.
Every theropod would be unbalanced if we removed the tail, now if spinosaurus had a very long tail, it would be able to balance itself.
Bear lips are useless when catching salmon. The lips would not be able to hold the fish, the teeth would.

I made this to be purposefully silly, unlikely and fun.
Except the quadrupedal thing, I now stick to the idea of more-often-than-not quadrupedal-aquatic spinosaur.

Ah, sorry.
But spinosaurus would not be completely quadruped as it's arms were not made to walk and as it's legs were long enough to allow it to be bipedal. Also spinosaurids had very flexible necks. Keeping it's head more upright (I think this is the word I am looking for) and closer to the sail bones would move the center of gravity closer to the hips.
