Spinosaurus in Saltwater?

I wish that the pictures worked, but I'm completely okay with this idea. I find it completely plausible, and to a point even hope it is true. Yet another reason why spinosaurus is possibly the most interesting dinosaurs discovered.

LORD OF THE SPINOSAURS - Oh, now this is a very neat and compelling topic! I happen to believe that, given the information you've presented for comparitive analysis, the hypothesis you've generated is quite feasible! Nature has a tendancy to "recycle" concepts within the biodynamics of various ecologies - especially the ones that yield high survival rates. I'm certain that, if Spinosaurus Aegyptiacus was a solid water-going animal, it would have definately learned to at least venture out into the oceans and seas from time to time in order to take advantage of the plethora of prey items therein. I would definately place this within the realm of plausibility! Thank you ever so much for sharing this incredibly interesting notion with us! :)

It's plausible. Most crocodiles can survive short amounts of time in saltwater.

Your hypothesis is as good as anyone could make it, and it is a cool idea to think that Spino ventured out to sea every once in a while to feed like a saltwater croc.  But I will only say sometimes, because despite its size, there were creatures out there that would make a meal out of Spino.  As well, it doesn't look like Spino was a truly fast swimmer, so I doubt a long open-sea voyage was a good option.  If and when Spino ventured into saltwater, I guess it was in brackish water.  Still shallow enough to be like it's freshwater habitat, but with a high enough salt content.

Thanks guys! Alphadino, I don't think there would be many (if any) creatures in the sea that would have odds in there favor against Spinosaurus, the biggest was Kronosaurus I believe, and Kronosaurus was only about 10 meters I believe.

^Even more adapted to water though.

True, but Spinosaurus could use those claws. Though in reality if the two met (which I am convinced they did) they would probably both avoid each other to prevent injuries.

I'm agree with that actually. I believe that Spinosaurus went into saltwater and that it had some feathers like penguins.

What an interesting thoery! Never thought about this. Sad I can't see the pictures but I know what you mean by this. Looging at the penguin and the Spino does suggest some salt water travel. If the Spino lived in the sald water is up to disscusion but I wouldn't dismiss the possibility of Spinos migrating during droughts. If there is a drought in Africa, swim over to another island/continent where there isn't a drought.

Very interesting, wouldn't be surprised if it did venture off here and there.
