Whats wrong with dinosaur reconstruction?

if the female had the structure then it would have made mating a complete mess, as you mentioned earlier. it makes much more sense for a male to possess such a structure

A hump would be no problem. A sail would indeed.

My guess is that Spino hunted fish during wet deason and on land at dry season. Similar to bears. I agree with you, that his jaws were not as weak as an gharials but it could not compete in bite force with carcharodontosaurus (which head operated like an axe.
 
spino could have been a scavenger if the season did get so dry. Charcadontosauris was not the only other predator and stealing a kill from deltadromedus, afrovenator, or dromeosaurs would have been easy for a spino
 
Many non-extinct animals will starve instead of changing diet. What is the proof that something, millions of years old, wouldn't have starved to death instead of changing diet? Proof...not theory.

evry predator today is also a scavanger. Its an easy meal that no meat eating animal passes. Beside that, bite marks were found on fossils of various sauropods which were too large to be hunted down. Some Spino just ate at a carcass.

The spines of Spinosaurus are also very massive and very similar to that of a Bison. Look here:

Spinosaurus was a notorious fish eater. We know that from fish scales that were sticking in his tooth. He needed massive muscles to move his head through the water. The sail is impossible. If Spinosaurus would have a sail and he would have fallen or simply rolled on his back, his spine would break and kill him instantly. The sail theory got completly thrown away from scientists today. It would have looked like that:

That hump could also save water and fat rescources.

About sauropods trunks, no there are no fossils found yet, which prove 100% for shure there was a trunk. While sauropod fossils are not rare, their heads are. In most cases the head is missing and in the cases a head is found we found no imprint of a trunk yet. What has been found are collagenous spikes similar to an iguanas on Diplodocus back.

And about Stegosaurus plates on his back. Beside the fact, that they would cause huge problems during mating, they are not combined with the bones. Those plates are heavy and would hang down at the sides.

Parthogenisis is a difficult topic, since we know dinosaurs had sexual dimorphism. We know male and female fossils so its most likely they reproduced sexual.

Ill buy the stego, but then what was plates hanging do?

No evidence of a trunk then. So passing your opinion as fact is BS, because there is 0 evidence to support such a theory.

That hump would still interfer with mating. The thickness of those spines is no where near what the thickness of a bisons bones are as. It also is completely smooth. Look at your typical bones. Where muscles attach its not smooth like those are. And what benefit would the hump provide? You listed water, but if they where a primary fish eater, a hump would be moot to store water if your hunting something that only exists in water. What other animals exist today with a hump to store water? Camels who would only run across water once in a blue moon. No species of reptilian fish eater today posses such a hump, nor do the various species of fish eating birds(theropods like spinosaurus).

Female hyenas have a mock penis. But thats beside the point. You have one fossil of a spinosaurus, one. With one mere specimen it is not possible to say, they lived like X because there isnt enough evidence to support X. I shall now hypothesize they lived like Y. Neither of us have any evidence to support our arguement.

MN brings up alot of good points. His jaws werent thin and fragile, they actually appear to be somewhat beefy. Sure not T Rex beefy, but not gharial thin.

Have proof that these where spino bites?
