The Spinosaurus

Technecly gharials and spinos are river predators and have many simillarities small jaws with pointy teath, have big body masses and leangth, and despite this have a fish diet

I was explaining to Cat something to cat about his statements, that's all.

Exactly Carno, another thing i have stated a number of times! And like i said, i look at it as more of an accessory for Spino.

Who knows, maybe Spino would hide in the waters and attack herbivores that came for a drink from the water.

Well, if we're doing this, here's how big I think the damn thing got.

Weight: 7-8 tons

Length: 50-55 feet

Here's why: The limited remains we have discovered of Spino are in poor condition. They were found in the Sahara desert, and erosion would have taken its toll on any fossil found in the desert. The remains discovered in 1912 may have been from a rather large individual because the average sized ones may have eroded away after millions of years of laying in the sand. 

What about the sail though? 

Another thing spino migth look bigger than he is by that frill on his back

Hiphop, your reasonings are opinionated, if you are going to say it was lightly built, please elaborate on that as well ;)

Cool. You can't compare s spinosaurs to anything living today because it is so different. My thoughts is that it had a different niche all together. I think it hunted 50% fish and the rest was hadrisUrids and baby sauropods.

@ Cat, technically, all crocodilians are river predators. They occupy that niche, and surely they do eat fish but the larger species are very capable of taking wildebeest, impala, and you name it( talking mainly about the Saltwater Croc) They have even been observed taking lions and wild dogs from time to time, so for a spinosaurus, a mid sized hadrosaur( ancestor of Ouranosaurus?) were to pass by, it surely wouldn't pass it up because it wasn't adapted to kill it. Shear size and possibly 6 foot arms with meathooks for claws are surely enough to cause death to prey

Theres not much to elaborat. On S-rex...

it simply means Spinosaurus didn't have a large amount of muscle compared to other theropods. in fact ALL spinosaurids appear to be loghtly bulit.

TY Nature has repeted designs that are succesfoul, like say rhinos to trikes, Wolves hunting in packs strategy to raptors, spinos long mouth to gharials, so maybe spinos design whas succesfoul by having lees competition for food

I agree with carno and was actually about to say that sorta.

But Happy, it seems that you always just take the latter side of anything towards Spino, so i dont think you should just do that strictly because its partial remains are in poor condition.

@ Tyrant King, well...yes we can. Morphilogically speaking ( i just butchered the hell out of the spelling on that..) Spinosaurus' skull is very crocodilian like. The conical teeth are also a shared trait, and that was one of our first hints to what this thing possibly ate. Conical teeth are good for gripping slippery prey, but they are also good at making sure prey doesn't escape the jaws also. Therefore, the diet of Spinosaurus can be established as not strictly Piscavorious, but also being able to take small - sized prey. Honestly, Spinosaurs weren't built to kill adults sauropods, so it wouldn't prey on them. Babies? Subadults? absolutely.

Spino rex, what do you think the bite force of spinosaurs is?

It's all just my opinion on the matter, and Spinosaurs were rather lightweight as stated by HHA. 

Well, the bite force is usally estimated at around 4-7 tons??

Closer to 2-3 tons 401. You're thinking Rex's bite there. 

I put it at 2-2.5 tons.
