Lets see, spinos jaws are too small to get a good grp of anigthing big, even if they had a big bite force they  would have a hard time, 2 animals that run out of patiance look for pray that is already dead or ding, 3 spinos claws where never found, 4 spino lived with hervivores to big to hunt if they wherent sick or young, 5 spino didn't only whait for fish he also whent underwater to get them, 6 spinos if no other option would unt pteradons, this means he whas around 80% psicover, 10% scavenger, 10% hunter

Hipho, calm down. You don't need to leave, and my sayings are the same as of Carno and S-Rex.

Hiphop, theres no reason to get hostile dude, you just arent elaborating anough on what you say, we are just using real life situations that still go on today to pinpoint how animals lived back then.

first, relax a bit HHP.

Secondly, we were just explaining that predators don't go charging into herds, nor are the actively chasing their prey for miles( with the exception of wolves, which simply run their prey to death. They hunt via ambush, and looking for the sickeest/oldest/smallest/ easiest to kill animals.

That dosent mean it couldn't hunt terrestrial prey!

Do you guys think I'm stupied? Obviously I know it would go for the youngest/straws of the herd but, Spinosaurus was a relatively slow animal, and was much more suited for hunting fish!

I was simply stating animals do run out of patience.

It would ambush and maul the prey to death.

And words cannot even describe how much research Michael Crichton went through to write that "fiction" book, Catzilla.

Raptor we are not basing on fiction, besides when animals run out of patience they don't hunt even larger prey they scavenge a lion for example intimidates cheetas

 would fil more often then not HPP but once it got its claws on it. Well bye bye herbivore.

Even the biggest predators go for the young!!! Especially the ones that run off the herd/pack.

No predators go looking for the biggest, healthies animals in the herd. They survey the herd/ animal in question, and if they judge it just right, they go for the attack. S-rex is right, the sick, old, and weak are what predators look for - which in turns keeps herbivore populations disease free and strong.

Are you kidding me? Strays are what predators look for, that and the sick ones, and if desperate enough, it would have no problem with picking off a member of a herd.

Yes your right CZ

@ Cat - yes, but it would appear we may have actually found a bit of its arms with this new mount by Sereno, as this is probably why the arms appear disproportionally short, rather then the longer ones we estimated using Suchomimus and Baryonyx.

So your saying a hadrosaur that can run at about 25-30 mph or a baby saurpod that's constantly protected by its herd are easier then fish?

Correct me if im wrong but wherent spinos claws never found and are estimated by asumtion?

Baby sauropods require more energy to hunt, plus spinos thin jaw means it can't have a very big bite force, even tough it migth scavee, by intimidating other predators

Even int he novels the dinosaurs get impatient!!! In soem scenes it describes the dinosaur getting impatient whenever they can't see Grant since their vision pecularities were based on movement.

@Tyrant king, actually, A study conducted in i believe 2009 shows that Dromaeosaurs actually very likely could have climbed trees; an excerpt:

The Manning team also compared the curvature of the dromaeosaurid "sickle claw" on the foot with curvature in modern birds and mammals. Previous studies had shown that the amount of curvature in a claw corresponded to what lifestyle the animal has: animals with strongly curved claws of a certain shape tend to be climbers, while straighter claws indicate ground-dwelling lifestyles. The sickle-claws of the dromaeosaurid Deinonychus have a curvature of 160 degrees, well within the range of climbing animals. The forelimb claws they studied also fell within the climbing range of curvature.

Spinos huge arms cause serious wounds to prey.

and if you really think tere like crocs then I say spinosaurs could hunt anything it wanted by ambush.

Hiphop, they most certainly do run out of patience. In predation in almost all cases, the predator goes for the easier-to-get prey, hence my reasoning.

Animals do run out of patience. Evidence? My dog. Other animals.

I estimate Spino's bite force as 3-5 tons, as well.

S-rex, lets not forget these aren't people. Animals when looking for food, don't run out of patience.

Spino'slong jaws and claws made catching fish easier than tring to claw swipe a biig prey, the reason he could be so big is little competition and the saill intimidates other predators, he won the figth wihout a battle

I agree with spino rex.

They don't have the exact same lifestyles. Would droneosUrs leap from trees down to there prey like modern birds of prey?

And I do belive the arms would be an advantage. A couple of slaps could kill a well-sized herbivore.

Good point Cat!

If I'm not mistaken, Spino had sensors on the end of its snout, similar to what Vipers have. That would help it in catching fish and such, and keep in mind, fish weren't small back then. 

It doesn't matter if crocodilians are bipedal or not, because we're talking about the skull. Mainly the dentition, which is similar to that of the Spinosaur family. That's a pretty good reference point, considering these guys have been dead for Millenia..

We can infer about its lifestyle by the skull, as that's pretty much basically all we've found of it with the exceptions of scant remains found here and there - though the Sereno find might prove me wrong.

3 to 4 tons is where i put its bite, more than enough to suffocate a large dinosaur.

PX see they are very simmillar

Yes, Cat, but another thing is that its hard enough to catch a fish with a fishing pole, so biting at fish that arent always to be claimed as his, it would lose patience and go for a more sizable and easier meal.

I put it at 3 to 5 tons.

T-K, Spinosaurs were very closely related to Crocodiles. That's like saying Raptors weren't birds because they couldn't fly.

Baryonyx Walkeri, scaled up to 55 feet in length, would have a bite force of ~2.5 tons. A Fully grown spinosaurus therefore would have a bite force of 3-3.5 tons

@ carnosaur are crocodiles bibedal? No. So we can't compare them. They had a niche similar to that of other spinosaur. 

Everything else you said I agree.

Thanks Allotitan!!!
