Solution for the Quadrupedal Spinosaurus

I'm not too sure if SPINOSAURUS had that the right muscles and bones to allow knuckle walking. Gorillas don't have claws so they don't cound as a good comparison. Sloths are better since they that've claws but this is a mammal and that is a reptile. Sloths don't use their claws like a SPINOSAURUS.

Spinosaurus had very strong arms and hands, so I don't see why it couldn't walk like that. As far as the gorilla comparison goes, sure they don't have claws, but the general position could be the same. And dinosaurs have many things in common with mammals(upright walking positions, warm blood, etc). Why couldn't this be a similarity too?

I guess so. And I was not shouting SPINOSAURUS it just autocorrects that way.

Well, I've nver thought of it that way...

Personally, I think Spinosaurus could switch from bipedal to quadrupedal when it wanted, but it would've probably been more comfortable walking on four legs. Apes can also move on two legs, but they usually don't. Spinosaurus would've probably been like this.

I agree with what's been stated. No doubt it could be a biped when it felt like it, but it most likely took a quadrupedal stance for the most part. 

scifie king i realy like what you said ubove this comment. i actualy didnt think of that.

I agree with you. Also National Geographic agrees with you, here is a video they posted. Here is the link in case the video doesn't show.

Bigger than T-Rex Spinosaurus

REX FAN 684 - I agree whole-heartedly with the assessment you've brought forward. Spinosaurus, in my opinion, has benefited immensely fom this revision; it's a much more insteresting and fantastic animal now that it's been given a unique niche!

    As for those whom state that Spinosaurus couldn't possibly have been a functioning quadruped for fear of blunting its claws, ask them this: how did other massive quadrupeds of the past walk about and not blunt their claws? It's patently simple: the very act of walking about sharpened their claws and kept them from growing too long - much in the same way that big cats scratch upon trees and rocks to keep their talons in check. We can even look to the giant monitor lizards of today for evidence that claws don't blunt under constant stress - they might crack and wear-down, but they continuously grow. Dulled claws, indeed! What nonsense. Sounds to me as though some individuals simply can't let go of their preconceptions that had Spinosaurus running about like some giant monster and eating other theropods that were 30+ ft in length (I'll point to Monsters Resurrected for this misconception).

    Regardless, thank you ever so much for sharing this theory with us! :)

Sure thing SR and I appreciate everyone's comments. I emailed paleontologist Peter Larson about this theory too. He said and I quote...

"Nice hypothesis!"

That must be a good thing, haha

REX FAN 684 - WOW! How very neat! That definately counts for quite a bit in my book! Keep up the excellent work! :)

Thank you SR :D

REX FAN 684 - You're most welcome, sweetie! You definately earned it! :)

YAAAAAAAY!thank you rexy for showing me the truth...of the world.

No problem Indy :)

SR, your statement was the quite the insult as i may point out. And i accept the possibility of this, but there is no inevitability to this yet, so am i going to accept its fact? Hell... NO.

Little rude/aggressive there S-Rex. Mind toning it down a bit?

Aggressive... rude... two words that absolutely do not describe my personality and mood, im being straight forward, there's a difference.

There's another way to do that...

You could say...

"It's possible, but I'll wait for further evidence."

Comes out a little nicer sounding don't ya think?

My overall tone was due to SR's comment, you didnt think i was going to be all rainbows and butterflies, did ya?
