Why Spinosaurus Wins

I'm a T-Rex fan and didn't like its substitution in JP3, but definitely not because the Spino killed it. I disliked Spino taking over simply because, to me (and I really mean me), the Jurassic Park magic, the one that took my breath away in 1993, lies in the T-Rex. It was the T-Rex that made me speechless when I was 12 and watched JP for the first time. It was the T-Rex that took me to the movies 4 other times to watch the same movie. It was this dino that made me watch the film over 40 times on tape (yes, until the fortieth, I counted). When I listen to John William's amazing soundtrack, it's the T-Rex that comes to my mind. That's why I couldn't care less when I read about facts that account for which of the two would actually win a fight due to strength, size or anything. If I wanted real facts, I would go watch a documentary instead of the JP films. If I wanted facts, I would completely disregard JP films because, come on, what are the chances of anything depicted there ever being real? That's why I didn't like to see the Spino rule JP3. At least to me, that was not the JP that completely overwhelmed me when I was young and kept doing it with TLW. And I don't dislike Spino. I just don't think it should be JP's star.

Well said, RexFan. That was very moving. . I'm on team Spino, but that's only because I like the dinosaur itself better than t-rex. I totally agree that Rex would most likely have the advantage in a fight, and I admire and respect both dinosaurs and think they are both awesome!!!

if only spinosaurus was discovered first, thinks would be different, MUCH different

RexFan90 has a point (that is truly the only reason I didn't like JP3 as much as the other 2). And I agree with Dinosaur.Fanatic, both are great, but I like T-Rex itself better. Spinosaurus Rex (nice name by the way), not as much as you think would be different (maybe Spino would have been called Tyrannosaurus Rex, which means Tyrant lizard king). But seriously, spine lizard king just doesn't have the same ring to it. Their names may have been different, and maybe what we know about them (T-Rex was discovered over 100 years ago and we are still learning about it, so really, Spino is like a child and our knowledge of it is limited, but that will change).

Ur right in respect that it would be called something different . It got called rex because at the time it was the biggest ! But it would t be spinos name . Cos spinos name is already quality! It dont need the rex bit on the end , i love the "eagypticus "! And there is still alot to learn and discover about spinosaurus! But wht we know about T rex as a fact ! Not opinion or theory, is that it has the binocular vision for a 3D world like us n any bird of prey due to the narrowing of the bridge of the nosel ,it has the sense of smell the equivalent of 50 bloodhounds , has thicker bone density , thicker skull density to absorb shock n sustain jaw and neck muscles to innisiate the bite force, banana sizedcurved surrated spikes as teeth with a 5inch route so they never broke wen biting down to the bone or biting tanks like ankylosaurus or battling with triceratops. He is so advanced evolutionary -wise is prob y he is so popular!! In 50 years spino may get his turn in the spotlight wen we know more about him and more have been discovered

Jhawkins That is also true that it had the evolutionary advantage. And Spino could get his time in the spotlight in 50 years when we know more about it (and possibly time travel). Spino probably would have been called Spinosaurus (or something similar due to it's sail). I think T-Rex was discovered before Spino due to location (seriously, who would even think to check in a desert).

@spinosaurus rex whats your problem? What do you have against T rex the animal? I like both creatures, though they messed up on spinos teeth in JP3 and gave him/her T rex teeth. Your hatred for T rex shows through when you bash t rex on everything including the poor creature's name. Spinosaurus has a great name, no need for it take T rexs name. Aegypticus sounds like a cool name, but they could latinized the word Pharoah. I'm on team Tyrannosaurus, but I love all dinosaurus equally. T. rex has Binocular vision and has more of a avian (Bird) brain opposed to spino's more reptilian brain. Tyrannosaurus might of had feathers therefore might of been Warm Blooded. Tyrannosaurus also has the strongest bite force. As for T. rex's vestial arms, he or she didn't really need them, also Tyrannosaurus hunts in packs like their raptor cousins.

Xenotaris If T-Rex did hunt in packs, it would most likely be family groups (parents and 2-4 kids that survived).

I know, I watch a lot of Dino-documentaries ever since I was a kid. Also wanted to add in that raptor part because both are coelurosaurs meaning they have feathers.

how would we know if it had binocular vision or not, we have no skin preservations or any thing of trex

They looked at how the eye sockets are in comparison to the snout and believe that T-Rex had binocular vision.

we've only had skin preservation on maybe 2 or 3 dinosaurs the most recent one being a hadrosaur we've never recovered a carnivore most of the time its nearly impossible to tell.... we have to make and educated guess also dont go hating rex fro being found first no one looks in deserts one look and i think its just a barren wasteland with nothing in it. stop hating t rex for being found first and being said to be better....

Hey "Spinosaurus Rex" I don't trust your opinion one bit.. Ya know why? On the thread I started "resurrect dilophosaurus" you said that the dilophosaurus grew as big as a Tyrannosaurus Rex which is completely false. (Do some research) Also, spinosaurus had a crocodile like head but it is very thin and flimsy and thoughit is bigger it wouldn't have "2 to 3 times a crocodiles bite force" it would probably have more but it wouldn't have more than a T- Rex. And to be completely honest that whole duel in the 3 film was completely ludicrous anyways because it was just a Godzilla jab and just made these animals look like monsters. Plus I believe that they would be very closely matched in a fight. Plus they were separated geographically I got my spinosaurus tooth from morocco and my T- Rex bone fragment is from South Dakota! No one should listen to Spinosaurus Rex because he doesn't know what he's talking about!

In-Gen It was Paden that said Dilo got to the same size as T-Rex. S-Rex (doesn't have the same ring as T-Rex) said Dilo got to 20 feet long. I do agree with the 2 to 3 times the bite force of a croc (probably just assuming, like how everyone assumes T-Rex was a hunter, I think it was, scientific evidence proves it, but apparently that's not good enough for some people).

correction i said it grew to about the same height and length not exact there was a slight height difference of about an inch and thats compared to a bull t rex not a female t rex (female Rex's were bigger then male rex's) dilo probably couldn't compete much with the rex, in terms it was "outdated" in "weaponry" due to being one of the first carnivores int eh early years of the dinosaurs

I thought you would have meant in height and length. Even if that was the case, Dilo would have been so light compared to T-Rex, and yes, it would be "outdated" due to the fact that T-Rex had two periods of time to evolve versus Dilo that was one of the first dinosaurs. Dinosaurs just didn't get T-Rex or Spinosaurus big early on. Where any of the big carnovores around in the Jurassic, or where they in the early Cretaceous and on?

I am amazed that all of you are willingly dense! Dilophosaurus lived in the Triassic period and nothing got as big as the tyrannosaurus! Length wise or height wise! I don't believe that you all believe this, do some research!

In-Gen I looked it up, Dilo lived in the early Jurassic. Some got as big as T-Rex. Gigantosaurus, Charcharadontosaurus, Spinosaurus, Mapusaurus.

Did ya notice that trex get to 43 feet in length not 23 feet! I can't believe you are also taking early jurassic yes but how much did you cross reference because they are so early it is early jurassic late Triassic . Dilophosaurus was the apex predator of its time there is no denying that but the jurassic brought along bigger predators that quickly outcompeted the dilophosaurus into extinction! You all need to go to a museum once in a while and see some of the skeletons and read up a bit on it:)! I can't believe you guys are being so dense about accepting the fact that you are wrong! Dilophosaurus never got as big as trex! And especially not any of the species you list above (

I'm not saying Dilo is as big as T-Rex. It doesn't take a genius to know that. I will be honest that I am pretty dense at times.

If your talking about when I said I thought paden had meant height and length, I didn't mean I thought that was how big Dilo got, that's just that I thought that was what he meant.

Ok that makes a lot more sense! I figured there could be one big idiot on this forum when it comes to that sort of stuff but not two, cool good to know you have got it. Please disregard all that I said to yourself but paden needs to read it

Apparenly you need to do some research In Gen, there were plenty of carnivorous dinosaurs bigger than Trex, mayyybe you need to refer to my discussion!

And another thing In Gen, when the HELL did you see me post that dilo is bigger than trex, x padenis the one who said that and i corrected him, so back off!

And dilo wasnt near the height or the length of trex paden, i have no idea where you are getting your info

AND I KNOW EXACTLY WHAT IM TALKING ABOUT IN GEN, DO US ALL A FAVOR AND MAKE YOUR FALSE COMMENTS ON YOUR OWN DISCUSSION AND GET THE HELL OFF MINE !!!

I think Spino would win. I don't have a top favorite dinosaur but Giganotosaurus, Spinosaurus, and T-Rex are definitely at the top.

Sorry for coming in on this but, I google searched and felt that you guys are missing quite a bit about both creatures. T-Rex's Bite - Most powerful bite known on Earth, contrast its bite to a Great White Shark (650 PSI) to a Crocodile (largest found was 5,000 PSI) T-Rex has a 6,000 PSI bite (ranging anywhere up or down from that point. The T-Rex's jaw shape gives it more damage and crushing power than that of the Spinosaurus. The Spinosaurus bite was NOT strong, rather its bite was intended to grab and lock in its prey (Like a Stork or Crane) and bring the victim in close for its claws to mangle. THIS would be a weakness if the T-Rex was an equal sized foe, but given that a T-Rex's head could fit into a Spinosaurus mouth, the Spinosaur could wrangle a T-Rex small in size like a Crocodile could do to a Lion or Zebra. If the T-Rex was big, the Spinosaurus would have an extreme disadvantage because its primary combat style is useless. It would have to resort to full body tackles and attempt to overpower a T-Rex, which may or may not work to its advantage. Spinosaurus physique - The Spinosaurus resembled a Crocodile in stature and biologically, therefore; its body favored MUSCLE over bone strength and because of this the Spinosaurus primarily cruised wet climates or areas. Spinosaurus adapted to the conditions they thrived in and took down bigger (defenseless) prey, T-Rex endured the conditions (Mexico, Texas, Mongolia vs Egypt for example) Diet - The Spinosaurus, like a Killer Whale, could round up hundreds of fish to eat and sustain its daily needs where the T-Rex would bring down a single prey to feast for a day or two. (Depending on size and injuries sustained for either creature.) Both would settle for scraps if they needed to. (Any predator follows this principle) Because of the environment they were raised in, its reasonable to assume that the Spinosaurus was able to obtain a consistent food source almost 24/7 from land and sea. Now getting back to the Killer Whale, the Killer Whale only has 1 other competitor in the ocean and that is the Great White Shark. Killer Whales have been known to attack and eat Dolphins, Penguins, Sea lions, and Sharks. Are T-Rex and Spinosaurus as intelligent as Killer Whales? Probably not, but my point is that the Spinosaurus' size gives it at the VERY least an ego that it can take down a T-Rex, easily. (This is the Spino's opinion, not necessarily fact) The T-Rex is equally as egotistical as T-Rex have taken down sauropods who were heavily armored, muscular, and as strong (if not stronger) than the Spinosaurus. Spinosaurus Fin / sail - It's weight is null and void and a stupid argument. The Sail is a liability to the Spinosaurus in that it constricts its mobility and flexibility. The Tail - The Spinosaurus tail is known for helping it balance and nothing else. The Tyrannosaurus Rex's tail is known for two reasons, Counter balance to the T-Rex's large and heavy skull and second for improved agility and was very flexible. The Arms - The Spinosaurus arms are 3 feet long, an additional 2 feet or so for its claws... The T-Rex's claws are 2 feet long with its arms roughly 1 foot. Additional abilities - T-Rex was one of few dinosaurs with depth perception and excellent eye sight (Ironic Jurassic park made that a weakness, in the books its a weakness to all the dinosaurs.) T-Rex had large nostril cavities meant for picking up the scent of prey like a Bear, the T-Rex probably could detect prey ranging from 4 to 6 miles away. (A bear can smell up to 2 miles for comparison) Finally the part EVERYONE is missing... Jurassic Park. Jurassic Park does not have dinosaurs, as Alan Grant stated in the beginning of Jurassic Park 3. They are mutants, therefore; possess abilities, characteristics, and unknown whether they are true or not. T-Rex vs Spinosaurus can swing either way in both reality or in Jurassic Park, but in the example of the movie they wanted to stir some feelings and change things up a bit. The Spinosaurus in Jurassic Park is not characteristic of what we know of Spinosaurus but, it's hollywood directing and writing. Just as the T-Rex has the same changes. Raptors also have a large change to them. As did the Dilophosaurus. People seem to forget these facts.

Okay dude, get your facts strait. 1: Spinosaurus had HUGE arms, probably at least 6 feet long, while T. rex had 3 foot long arms that where super strong and could probably lift up to 450lbs. 2: there is only one sauropod that we know of from late Cretaceous North America, and it didn't have armor. It wasn't a Titanosaur (I might be wrong though, I haven't checked my sauropods in a while) 3: T. rex probably didn't have the strongest bite. That would belong to Sarcosuchus, Deinosuchus, Megalodon, or maybe Prussasaurus. One of those animals probably had the strongest bite. 4: compare a Spinosaurus bite to a regular Crocodile, and it would be at least 2 tons at the minimum (if crocodiles and Spinosaurs have a similar jaw structure and bite). Crocodiles have stronger bites as they get larger, and the largest croc today, the Saltwater Crocodile, has a bite force of 2 tons, and its only around 20 feet long. Being a bit conseritive, a bite foce for Spinosaurus would be around 4 tons. 5: Spinosaurus was probably around as heavy as a T. rex. Now, this is debatable, but I have good reason. Once again, I refer to a 60 foot Ornithomimid being around x tons (I really can't remember everything, but the X I think is around 6-7 tons, and that is how heavy I would consider an Ornithomimid that long) and, because Spinosaurus is a lot thicker than an Ornithomimid, it would be a lot heavier, at least 9 tons.

Alamosaurus, the only sauropod from late Cretaceous was a titanosaur. T-rex's arms were about 3 ft long and could lift about 450 lbs. Now, it's claws were only about 3 inches long. Spino had arms in the 5 ft range and claws well over 1.5 ft in length. Both were titanic killers with their own strengths and weaknesses. It's nearly impossible to say which would win.
