Agreed.

laides and gentlemen...KONG, THE EIGHTH WONDER OF THE WORLD!!!!!!

thanks for all the support guys! i will try to get ep 1 this weakend! so if you want to hear from Robby's magigic adventures, then i sugeast following me.

agreed it would confuse the hell out of everyone. people dont exactly like change or in the case of dinosaurs pay attention to it. people still think brontosaurus still exists

The general puic.

You mean us?

It would confuse the heck out of the public.

I don't think it's going to change Spino being the favorite dino of people, just a size deduction and quite a bit of rethining about the Spinosaur family tree

Looks pretty cool, like a crocodile with a sail. If this turns out to be true I'd still prefer the spino to the rex.

I honestly just find if appalling.

Also, forgot to state this earlier, but I agree with S-Rex and all, but especially on this depiction, as in the drawing- it's God-awful! Seriosuly, it honestly does make me want to throw up for some reason,s ounds crazy, but just... no...

...

...

No.

I'm sorry for the short post guys. I am on my phone and it loggs me put constantly and I am eating and doing other things right now.

Thanks :D

any time, i gues...

Not saying it isn't possible, but with the physiology of theropods not being analagous to mammals i just don't see it as plausible..

Didn't really see this find shining the light it did on spinosaurus either, but eh i'm open to new things.

I think it was mostly bipedal and probably just occasionally went on all fours.

Ok. didn't know that. Thanks for the info.

(Just want to clarify that I too dislike that portrayal, as it seems disproportional to me.)

I don't like that reconstruction..seems to mammalian/theraspid in nature to me..

Gorillas have a gait Characterized as "knuckle walking", but they are capable of a bipedal gait as well. I don't think i need to show examples, mainly because we've all seem it at some point. Also, Gorillas don't have claws, they have short nails that aid in making the "knuckle walk" possible, as they aren't long enough to dig into the Gorilla's forearm.

Spinosaur arms seem a little thin for a quadrupedal gait, and the 6-9 inch claws it sported woulld have sank into the substrate of its time, not really idea for quadrupedal locomotion-  foot claws are oriented differently then those of the forearms, so that's why this wouldn't occur in the legs.

ontersesting.

No, I don't think it would wear out spino's claws, as it would likely walk similarily to a gorilla, as seen in this picture:

Ya those huge claws on its forearms would be bad to walk on .

First of all, nice find!

Also, I'm with TK and Carnosaur. I don't buy the bipedal theory. Also, it could have a bit of weight in its tail to allow at least a bit of bipedal movement. This would allow it to walk bipedally or quadrupedally as it pleased. Also, I don't really think its scyth-like claws would allow too much quadrupedal movement, as this would wear and tear its claws. It would probably move bipedally on land, and quadrupedally on the shore or in water. 

I say about 8 tons.

it's fine.

Going back to the first page comments that were made, yes Spinosaurus isn't the twenty ton bipedal slaughterhouse it was made out to be in the early 2000's, and man do i know some Spino fanatics that really take it to a new level, but we don't have that here. Idealogy on Spinosaurus' size was based on the assumption it was closely related to Suchomimus/ Baryonyx. Now...i don't know what this thing is "closely" related to, because its physiology appears completely different from what we were inferring.

That's the thing about this field...you never know what you're going to find..

3-5 tons is too light, as i see you put it at. 3 tons is Suchomimus sized! spino was a good 10-15 feet longer than it, it's quite obvious it would have a decent size advantage over it

I kinda figured people would assume I meant similar sized. Ah well, that's one thing about me is I tend to assume people know things when they don't. Sorry guys, next time I'll clarify if I remember. 

Awesome!!!!

should have clarified that a while ago,happy.

Any ways, it's almost a certaintythis thing was neither fully aquatic or Quadrupedal, it just shows adaptations towards a semiaquatic lifestyle. Crocodilians any one?

don't mentioncrocodilians are quadrupedal, that's irrelevant and basic knowledge...

That paper states that while most of the weight is in front of the hips, it's quite probably a partly bipedal creature.

Nice find.

I've found the paper onit, i'd advise all y'all go check it out

I'm not saying Rex can't be beat. I'm saying it would win more often than not. That can mean 10/10, that can mean 9/10, but tha can also mean 6/10. I'm not saying Rex was unstoppable, I'm not saying it was invincible. I'm simply saying it would win a one on one predator battle more often than it would lose a one on one predator battle. 

If it wasn't clear in my previous post, this is against similar sized predators. 

@ mr.hsppy why don't you think a other theropod can not defeat the tyrant lizard king？

Alright, last attempt at defending my opinion. 

IMO, Rex would win more often than not against SIMILAR sized predators. Against a predator that was, say, 4 tons heavier, the odds balance out and said predator would beat Rex more often than not. 

You know what I mean carnosaur:) rex is the only theropod with a bite study done on it. And people say rex's bite can not be topped. but many other theropods had strong bites.

KONG!

Rex's bite is stronger then the other theropods, with a median bite force of ~5-6 tons. Others came close or even exceeded that, but it's something that really hasn't been studied very much at all. If we were to put say, the top ten largest theropods in a bite force study, we might have some suprissing numbers - especially since the megalosaurs had jaw mechanics on par with the Tyrannosaurs. Edmarka rex - probably synonymous with Torvosaurus, was a 11-12 meter megalosaur, something that big would give Tyrannosaurus rexa run for its money in that department.

Cat, Penguin feet aren't useless by any definition of the term. While penguins are adapted to water bound locomotion, that doesn't mean their feet aren't useful.

In fact, some species are suprisingly fast and agile - mainly the Rockhopper species- Eudyptes spp. mainly. These species are capable of speeds up to 15 mph, fast for a bird with ' useless' feet, wouldn't ya say?

Why do you think it could win agsinst other predators da often and seriously many theropods can beat it in a fight. Do you think it will win because of its only true weapon. Why is Rex's bite so much deadlier then others? Seriously it'd not. It had no competition  when it lived so it is not a theropod killer as some say. And animals like spino, charcar, and giga lived with big, tough predators and constantly had cometition for resources. More do the rex. So don't say rex had an advantage  in that field. and Rex's binocular vision is not gonna help it place bites or anything like that and sill predators have it. Just Rex's was a bit more adapted and it is not going to give it an advantage.

In a one on one predator vs predator, I'm of the opinion that Rex would win more often then not, but that's because there were no predators that outweighed Rex by a significant margin. 

There were predators equally as large as it;they don't have to be substantially larger to kill it.

Well penguines are bipedal but its feet are almost usles

I never said it was unstoppable. I said that I'm of the opinion that it would win more often then not against other predators one on one. That's all. Where do you see "invincible" or "unstoppable" in there? 

Anywho, I agree with you Carno. 

Artistic depiction =/= factual evidence. Just because it isshown in a quadrupedal stance doesn't mean it was fully quadrupedal. I'll have to dig around for the paper on these new finds..

From that article, i'll just highlight something some of you seem to have glazed over a tad bit

"From tip to tail, he says, a digital reconstruction of those bones (done with funding provided by the National Geographic Society) tells a story of semiaquatic adaptation. The creature's skull sported small nostrils midway up the snout, perfect for breathing with the jaws submerged like a crocodile. Also similar to crocodiles, the tip of the snout possessed nerve and blood vessel channels, sensitive to sudden pressure changes in the water from fleeing prey."

It seems the idea This spinosaur was more crocodilian in nature are correct, and while the back legs are suprisingly dense for a theropod( most theropods have hollow bones) that doesn't mean it was 100% quadrupedal, saying otherwise is..again..nonsensical..c'mon guys you're better then this for pete's sake.

Experts remarked on similarities between the leg bones of Spinosaurus and Penguins, stating it helped maintain bouyancy in the water. Need iremind you penguins are still bipedal?

A Quadrupedal gait is likely, but not a 100% fixture in the life of Spinosaurus, It most certainly stood upright, if only a marginal percentage of the time.
