Let me reveal mine now.  Before I went on vacation to Alaska mine was the Iguanadon. After going to an Arctic dinosaur museum it is now an Arctic T-Rex. I cannot find much information on this species but it existed.

Dinosaurs in the Arctic?
Fossils of a carnivorous dinosaur have been found in the Canadian Arctic - high above the Arctic Circle.

Hans Larsson, a Canadian paleontologist, found the bones of a tyrannosaur on Bylot Island, off the northern tip of Baffin Island.

This beast would have been huge - perhaps up to 10 meters / 33 feet long and weighing as much as 2,500 kg / 5,500 pounds - with razor sharp teeth and claws. If polar bears had been around 70 million years ago, they would have had to give up their title of "largest land predator".

This is the first time any evidence has been found to put these predatory dinosaurs at such a high latitude. The Arctic was a very different place then - Bylot Island was forested - but a lot can happen in 70 million years.








I'm gonna try to stay this time. For real, real.

is not a T-rex, its a tyrannosaur...theres a difference...LOl, it sounds a lot like Cryolophosaurus of the Antarctic..execpt Cryolophosaurus is sweeter...with its head crest and all...

I have read some rather naive comments on this thread that stated spinosaurus was a "weak-jawed specialist fish eater".  This is total nonsense, and based only based on the fact that spinosaurus has a head/jaw structure similar to a crocodile.  I wonder if these writers are aware of what big crocs mainly eat?  Basically everything in africa smaller than an elephant, rhino or hippo that wanders close to a watering hole.  And as for "weak jaws", guess what, crocodiles have the most powerful jaws of any living creature today, and very probably, the strongest of any animal that ever dwelt on this earth, because there were also giant crocs in prehistoric times that no dinosaur would ever want to tangle with.

The now famous duel between T-Rex and Spino in JP3 was created with the technical advise of knowledgeable paleontologists.  Yes if the same size, a t-rex has a weight advantage, but the spino would have a wider mouth gape, and much larger, powerful arms to fight with compared to the almost useless arms of the T-Rex.  Now, make the spino 25 feet longer than the T-Rex, like the original Spinosaurus Aegyptus, and the outcome is a "no brainer", obvious win for the Spino, for it now has every advantage, including weight.  And if it wasn't noticed in the movie, yes, this spino was considerably larger than the T-Rex.
This is very apparent when you see the full size robotic dinos side by side, and its larger size is remarked in the movied diaglogue as well.

Spinosaurus still rules as the biggest, deadliest theropod ever discovered, and with its huge croc-like jaws, and the largest, strongest arms of any theropod, is more than a match for the biggest Allosaurids like Gigantosaurus as well.  Some spino teeth have been found that suggest monsters of over 75 feet!   I believe the spino grew larger than any other known theropod because it apparently shared the same swampy enviroment as the gigantic prehistoric crocs, and had to intimidate them to survive.

Oh, spino is very rare, but their teeth have been found imbedded in the vertebrae of two different pteranodon, and bones of an Iguanadon were found in the stomach region of the spino relative Baryonyx.  They definately ate more than just "fish", just like crocodiles do.

Your speculation about the size of Spinosaurus aegypticus is your opinion...just like evreyone else's view....I could easily make an arguement that Carcharodontosaurus saharicus/ Giganotosaurus carolinii are the biggest carnivorous dinosaurs of all time...
The facts do not lie, to date, the largest dinosaur teeth ever found were 7 inch "steak knives" belonging to Giganotosaurus!

Also, you have no right to call people who say "Spinosaurus ate fish"
naive...I did not hear anyone call them weak-jawwed (correct me if I am wrong). Spinosaurus's teeth were adapted and designed to hold fish...They were conical and curved back...no way they were designed to slice through the meat of another dinosaur. Yes, I agree that they could of eaten other dinosaurs, and They did, BUT, it was because they are oppurtunistic feeders...just like how Crocodillian teeth are designed to snag fish, they don't mind snapping at birds, turtles, and mammals...

Also, to call JP accurate is higly doubtful...If the Spinosaurus was so carefully designed, then why were the Velociraptors blown way out of proportion? The allure of money and thematics is way too powerful for them to model the dinosaurs accurately original.gif

Saying Spinosaurus is the "largest known theropod" is neither speculative or opinon, it is fact, until fossil evidence of a larger theropod is found.  Though incomplete, the original Holotype was calculated by competent paleontologists to be 65 feet long, and this has never been seriously challenged.  As for tooth size, you can probably buy an original 7 inch spino tooth on ebay today if you look.  I have one almost that long.  Common sense should dictate that a spino tooth is a far deadlier "weapon" than the fragile "meat slicers" of the other theropods, very narrow and prone to breakage, unlike the stout, conical, indestructible, but equally long teeth of Spinosaurus, set in huge jaws that could easily punch through a giant turtle or T Rex skull with the same alacrity.

I agree that there are many faults in Jurassic Park, but in this case they merely took the largest sized, documented T-Rex and Spino and drew the "logical" conclusion.  It is indeed naive to think a 40 foot theropod *without arms" (meaning arms too small to be useful in combat), would have any advantage against a 65 foot theropod with probably the largest arms of any carnosaur, much larger jaws, and the advantage of weight/mass.  I did not even mention the thermal regulating sail, which may also allow Spinosaur to be active when other theropods are sluggish due to ambient terperatures. True, if the creatures were exactly the same size, Spino would not have all these advantages.  Then it would be a fairly even match, with T-Rex's greater weight countered by Spino's much larger arms and jaws.  Realistically though, I doubt the real life dinos, if they could be brought together, would risk a fight to the death unless they were starving.  One would normally "back off".

Crocodiles are born as fish eaters, just as I am sure many theropods are born as insect eaters, irregardless of the dentition.  But most large Nile Crocodiles however subsist almost entirely on large warm-blooded prey.  Similar structured American crocs, even as adults, largely consume fish, but availability of prey has a lot to do with it.  I have a 5 foot  monitor lizard that has serrated narrow teeth exactly like a miniature T-Rex, and can swallow whole rabbits, but loves to eat banannas!

In short, the largest predatory dinosaur yet discovered probably ate "anything he wanted to", even if born a small, probable eater of fish and frogs in its apparent swampy environment.

Consider too that only one Spinosaur A. has been found and it was a huge monster some 35% bigger than the next largest Theropod. Over 20 T-Rexes have been found and around 40 feet is about the max.  From only one specimen we have no idea if this is just a small, or average spino yet just this one is far bigger than every other known theropod.   And even more significant, I even recall something in the description about certain bones not being fused yet, which indicated this huge spino was not even an adult yet!  This is why an estimation of 75 feet for an adult is quite realistic.  This would make it almost twice the size of an adult T Rex!

It is unfortunate that this greatest meat eating dinosaur ever found was blown to bits in Berlin during a WWII bombing raid.  I hope more will be found soon.

ps. Yes the Velociprators were "too big" in JP, but we both know there were large Dromaesaurs by other names these could have accurately represented.  They chose "Velociraptor" only because they thought the name was important, and they were right, for now it is a household word.   Oh, Raptor Red was silly, and I believe most serious paleontologists count Bakker as something of a charlatan and ehibitionist, but don't take my word for it, talk to some of them.

There are several "faults" with what you say about Spinosaurus. First of all, the Specimen that was housed in berlin during WWII was only 45 feet long. It never was over 50! The media always stretch the truth. Still, the largest ever documented teeth belong giganotosaurus...no teeth has been documented longer.

Second, it is still not proved that Spinosaurus is the largest...Of right now, Carcharodontosaurus is the leader with 46 feet...That might change in the future...but untill then, Carcharodontosaurus  is the heavyweight champion.

Third, I never said Spinosaurus never ate large herbivores, I just stated that their teeth are meant for fish, just like crocodiles...its a proven fact that they eat other dinosaurs....just like you said, availability of prey, and they are also oppurtunistic feeder.

Fourth, the "Velociraptors" in JP, although their size could fit another dromaeosaur, are way too fast and samrt, no way they could know how to open doors and push out wents, and no way they could run as fast as ostriches...

Fifth, for large prey and meat, teeth that belong to tyrannosaurs (steak knives) are much better suited than the stout, conical teeth of Spinosaurus and its realtives (baryonyx, Suchomimus, Irritator, and a albeiasaur in Madagascar).

PS, before you attack Bakker and my taste in books, please read his other books. Some people like Fictional stories...Bakker was just adding some creativity and humor to paleontology...RAPTOR RED is purely fictional.

There are other paleontologists that would say he added "fiction and creativity" to his supposed, "scientific" works as well.  Many say his theories are flawed and reckless.  Much of "Dinosaur Heresies" can be thrown out for what we now know about dinosaurs today.

A number of scholary works state the Berlin Holotype of Spinosaurus a. was 65 feet long, as well as the fact that it was appaently still a juvenile.   Some paleonotologists are as "big a kid" as anyone else, and I am aware of those who are now trying to dispute this, wanting their favorite theropod to be "biggest" even if it obviously isn't.    

The point though, from the very start of this discussion is that the JP3 Spino reflected this size superiority, so it was not unrealistic for the far bigger spino to be the victor in this battle.
