To much real-life information

Yesterday I deleted a huge amount of content from this article. I don't like to erase the hard work of my fellow parkpedians, so I owe you all an explanation. This article had a very long section discussing the real-life Spinosaurus. I don't like that for two reasons. 1) This is a Jurassic Park wiki, the animal is well described (by far more compitent people) on Wikipedia. There is no need for us playing a dinosaur wiki. 2) Extra sections of text are just more sections than can be vandalised. Since most of us don't know all the in dept details of this animal, there is a huge chance some of us will see improvement as vandalism and the other way round. We can better stick with JP related information.

Ofcourse, when scientific facts need to be told to criticize or defend the animal's portrayal in Jurassic Park media, we have to give that information. BastionMonk (talk) 09:41, November 12, 2013 (UTC)

Henry Wuu said the Dinosaurs are not like real life Dinosaurs so your argument is false and bs. Real life wiki info should only be used when we DON'T have info for the said Dino. In Spino's case we have plenty of info. QuakingStar (talk) 02:42, August 1, 2015 (UTC)


How can a dinosaur that's just trying to stay alive be "villainous"? The Spinosaur isn't an antagonist either. If trying to feed yourself is villainous, than everyone on this wiki is either evil or dead. Which is certainly not the case. So in short Spinosaurus isn't an antagonist.

In some ways I agree, but in others i don't. It is just trying to survive, but If anything were trying to kill me, i would definitely vilify it.
The Velociraptors were definitely villains, Muldoon said they would kill for sport, not only for food. Whereas the adult T-Rex in the film would kill just for food (Gennaro). In the book, the adult T-rex never killed anyone, only the juvenile did. I just think you wanted to give a shameless plug for Evil Dead.. hehe.--YingYang My Name Is Tom (Talk / Edits) 17:12, 24 July 2009 (UTC)

Lol. Guess your right.

In nature there is no good or evil, anything an animal does, no matter how cruel or disgusting it may seem, is simply an attempt to stay alive another day, which is something that Disney can't seem to get through their thick skulls (in fact, such thick skulls that I classify them as pachycephalosaurids). The Spinosaurus, having a brain the size of an apple, certainly could not be a villain. As for the raptors, possibly but even then I still wouldn't go as far as calling them "villainous".

I had another thinking. Is Jurassic Park films or novels can actually stated a creature as "villain"? Well, Dennis Nedry or Lewis Dodgson can be considered as evil, but how about the dinosaurs?

Would the editors of this article PLEASE stop calling the Spinosaurus villainous. Using words like "villainous" for non-human animals only has a place in Disney cartoons, and this certainly isn't Disney. Just because the Spinosaurus waited for the humans to notice it before it attacked doesn't make it villainous. It was probably just waiting until it was too late for the humans to escape, when it would have a guaranteed chance of getting a meal. Just because the raptors kill for pleasure doesn't make them villains either. In Africa, hippos kill more humans than any other animal in the region, often with little or no provocation from their victims. They very likely kill people just for the sake of killing, just like the raptors. But does that make them villains? No!

I agree - even though Spino relentlessly chased the group, it doesn't make him vicious. He was merely attracted by Amanda's megaphone and wanted to devour as much as he could. Even though he persisted trying to devour the group, he was eventually scared away by the fire caused by Alan's pistol. He didn't try to withstand it, but instictively ran away for good. It was just going on intincts, so he is no good example for villain nor main antagonist at all. Therefore, I suggest to remove him from Category:Main Antagonists.--844996 08:00, April 23, 2016 (UTC)

Spinosaurus in Jurassic Park IV

Soon Jurassic Park IV will be released. I have a question, will the Spinosaurus from JP III or a new Spinosaurus appears in the film? --VenT-rexBrennenburg, 08:45, April 1st 2012.

I always imagined that the JP3 Spinosaurus died in the fire, but maybe a different one will appear. Come to think of it, how the hell was there a fire on the lake? 14:30, April 10, 2012 (UTC)

Ehem, ehem. the oil from the boat splitted on the water surface, when Dr. Grant shoots the flare, it burns the oil. And no, the Spinosaurus escaped the fire. It's not dead yet, unless an adult T-rex defeat it. Maybe there's only one Spinosaurus on Isla Sorna. --VenT-rexBrennenburg, 19:42, April 10th 2012 (UTC)

Another possibility

Perhaps the JP/// Spinosaurus wasn't on the InGen list due to the following reason: perhaps Spinosaurus wasn't planned for the park, but was created later, after the disaster on Isla Nublar. Perhaps the Troodons managed to escape their extinction on Nublar by swimming to Sorna, where they got so out of hand that InGen created Spinosaurus as a sort of dinosaur exterminator that they released onto the island, hoping it would wipe out the Troodons. 14:39, April 10, 2012 (UTC)

Hmm, the fact that the Spinosaurus is the largest predatory dinosaur on earth might help him to eliminate, or at least controlling the Troodon population in Isla Sorna, IF they made it that far (Isla Sorna is on the West of Isla Nublar, 87 miles if I'm correct). But what will happen if Troodon Pectinodon become the apex predator in that Island, where they will rewarded as "King of The Dinosaurs", more than T-Rex? --VenT-rexBrennenburg, 19:30, April 10th 2012 (UTC)

i think that spinosaurus was a phase b attraction for jurassic park but he is never brought to the park because of the isla nublar incidentMarkosaurus 1 (talk) 13:22, August 14, 2012 (UTC)

What if the Spinosaurus was made in Sorna to go to Nublar, but InGen needed to test if it was safe enough to use as an attracion in the park because its awesome power. Then when they discovered it was too powerful for the park, they let it live out the rest of its days in Sorna. Sirmooasaurus Awsomi (talk) 22:22, June 18, 2013 (UTC)

Spinosaurus Actual Size

In some stuff, the spinosaurus is said to be 30ft long, in others, they say the Spino's length is 42ft, then in more stuff, Spino is said to be 60ft, in other stuff, Spino is said to be 72ft. I think Spino's length is the 72ft and 60ft because in 1914 (not sure if right year or not), spinosaurus agypticus was discovered, and estimated length was 60ft long, then its bone were blown up during WWII. After that sometime in the 80s, they discovered a lower jaw of spino, and that spino's estimated length was 72ft long, they named it Spinosaurus Morroconus, I just want to know what you guys think is the real one.  Sirmooasaurus Awsomi (talk) 22:22, June 18, 2013 (UTC)

I've seen estimates all the way to 60ft long, but most are somwhere in the upper 40's, somewhere around 45-50ft in length. Fredrich von Huene in 1926, Don Glut in 1982, and Greg Paul in 1988 all listed it as 49ft long, while François Therrien and Donald Henderson in 2007 restudied Dal Sasso's 2005 estimates (where he came to the extreme 59ft estimates) on spinosaurid skull length determining size. Unlike Dal Sasso, who assumed Suchomimus and Spinosaurus had the same body proportions (this is why assumptions can be dangerous :P), Therrien and Henderson looked at a larger variety of theropod skull to body ratios to make their estimates, and like others before them found estimates on the upper 40's range. Take a look at this diagram:

Spinosaurus skull length

Note that Dal Sasso's reconstruction isn't actually 175cm long when measured in the standard way (Pmx - Qj aka premaxilla (nose tip) to quadratojugal (back of the jaw). The 175cm that Del Sasso et al. published refers to the longest point of the skull, which in the case of Spinosaurus, happens to be the back of the TOP jaw, or squamosal bone. This is why Therrein and Henderson 'downsized' (more like corrected) MSNM V4047's skull length for their size estimates.

But frankly, the largest factor in preventing Spinosaurus from becoming both 60ft monstrosities is the environment, something that is as important to studying as the fossils themselves. Spinosaurus has two major terrestrial competitors: medium-sized terrestrial predator Torvosaurus and apex terrestrial predator Carcharodontosaurus. Spinosaurus literally does not have the room to grow to such a size. It was likely eating gigantic fish, with scraps on the side. Now, does that mean that this sort of environment can support a 55ft Spinosaurus? Yes, but within reason. Not every dinosaur grows to it's max, fossil evidence supports this. Tyrannosaurus, for example, can grow up to 43ft, but the average based on fossil evidence is 38-40ft. Not every animal reaches it's maximum, as I've explained. There's competition for resources and mates, and these competitions can result in the death or severe injury of one of the competitors. 

And finally, Spinosaurus marocannus has not been considered a valid taxon since the coing of the nomen by Russell in 1996. The specimen attributed as S. marocannus were later found to have been misestimated and thus the name is considered as likely a junior synonym to Spinosaurus aegypticus. {{SUBST:User:Jhayk' Sulliy/Sig}} 22:49, June 18, 2013 (UTC)

The actual Spinosaurus in JP3.. called Spino according to the directors was 70 feet long(roughly 21.336 meters) about 20 feet tall at it's crest and 12 tons. They say 12 here but in real life it was estimated to be at most 18 tons

Therefor Spino was the biggest carnivorous Dinosaur ingen ever created, including I.Rex. As shown here against the 14.5ft tall T.Rex Young Adult, Spino is MUCH larger.

QuakingStar (talk) 06:35, June 17, 2015 (UTC)

We can't know this because it is possible InGen recreated Gigantosaurus. Anonimo777 (talk) 10:30, June 17, 2015 (UTC)

Even in real life Spinosaurus was bigger than Giganotosaurus and Carcharodontosaurus the JP3 Spino had a confirmed 70 feet max length and towered over a 14.5 feet tall T-Rex Sub-Adult. It was more than 20 feet tall making it the biggest Dino InGen ever created, and I see exactly why they left it on Isla Sorna instead of bringing it to Nublar, because it was too much.. shown by how it busted right through that huge fence with its body alone. Somebody needs to add it to its page 04:29, June 18, 2015 (UTC)

 I will!
Spinosaurusrex, July 2015, 001:10

Here is my conclusion: Spinosaurus was 60 ft long, possibly even 78 ft long, and I think it outclasses Giganotosaurus and T-Rex in every way. As for the discussion about Spinosaurus VS Indominus rex, I think Spinosaurus would win. If it fought Vastatasaurus rex, it would probably kill it. This is my opinion and I personally think it is the most accurate. BETTER BELIEVE.

Spinosaurusrex, July 2015 008.59.

Against the 25 feet tall, 70 feet long Vastatosaurus Rex's from King Kong?? No.. I love Spino, but he can't beat a V-Rex their skin thickness and toughness, their weight and size, and their jaw power is FAR above a T-Rex's and if V-Rex only got ONE bite in, it is over for Spino.. Spino undoubtedly can kill a T-Rex or I-Rex.. but a V-Rex? that's pushing it man. QuakingStar (talk) 05:59, July 29, 2015 (UTC)

Well, not if Spinosaurus was 78 ft. Plus, Spinosaurus is 36 ft tall and weighs 23 tons. It would probably win. However, it still would at least be a difficult win for Spinosaurus. Spinosaurusrex, July 31, 2015, 009:28.

Spino from JP3 was no longer than 70ft tall and was 23 feet tall max, he was 12 tons max. The numbers you just used were made up.. He is shorter and lighter than a V-Rex by 2 feet and 3 tons. He does not have the same kind of skin as a V-rex. He would lose. QuakingStar (talk) 21:15, July 31, 2015 (UTC)

Henry Wuu made it clear these Dino's are different than real life Dino's. Hence this Spinosaurus being so Gigantic, so strong, bipedal, and so evil. Why has his length of 70 feet, and weight of 12 tons not been added yet? the real life wiki info should not be added on this sit as logn as it is not needed.. we were given sizes for the T-Rex's and Spino from JP franchise..  QuakingStar (talk) 21:32, July 31, 2015 (UTC)

movie mini series?

The "movie mini series" sounds like fanon because I doubt that a spino and a trex could be that anamorphic in the Jurassic Park universe.4DJONG 15:33, 6 August 2009 (UTC)

Please leave the video! I think it gives the page a dramatic sequence!


Spinosaur shown to be able take on young un fully grown Trex. As it was able to show great strength tp pulling small jet that broke in half easily as shown to be able to twist trex neck. It was even shown to be broke through a large metal gate to use great brute strength.  

Spinosaurs shows to be able to take the powerful jaw strength from young Trex that it was even to take attacks from it. 

With great stamina on its side was able to chase the humans long distance and able to fight off T-rex with no sign of problem. 

This spinosaur even shown to be able to swim well as it was able to hold its breath for certain period of time. 

Sign your sig next time...

Check this out Directors made Spino to be bigger, badder, and faster than a T-rex and that is how it was designed and built. Also the T-Rex that Spino fought was the size of the Lost World T-Rexes which were Rexy's size.. therefore the Spino is the biggest, fastest, strongest Carnivore ever including Rexy and Indominus. QuakingStar (talk) 06:30, July 29, 2015 (UTC)

Dinosaur growth rate

As to why we didn't see the Spinosaurus in The Lost World and why the Indominus grew so fast.. Jurassic Parks Novel has an answer to those basically..

"In this hatchery, we have produced more than a dozen crops of extractions, giving us a total of two hundred thirty-eight live animals. Our survival rate is somewhere around point four percent, and we naturally want to improve that. But by computer analysis we're working with something like five hundred variables one hundred and twenty environmental, another two hundred intra-egg, and the rest from the genetic material itself. Our eggs are plastic. The embryos are mechanically inserted, and then hatched here." And for how long they take to grow "Dinosaurs mature rapidly, attaining full size in two to four years. So we now have a number of adult specimens in the park." Spinosaurus was most likely a hatchling in The Lost World.

QuakingStar (talk) 08:54, July 31, 2015 (UTC)

Spino weight and size etc it was nearly 25,000lbs. The T-Rex was not a Sub-Adult, you people need to stop making shit up in fact they even used the Lost World Female T-Rex for the movie. But painted her to be a different color. I am removing that bullshit sub adult info from this wiki pages QuakingStar (talk) 21:52, August 22, 2015 (UTC)

Skeleton Identiy?

I've been looking around and stumbles upon this link regarding information towards the Spinosaurus in JP3. I need someone to verify this before I edit the page, I feel like this is the safest option. Thanks.



With the return of sigilmassasaurus; I think we all agree how inaccurate 2014 reconstruction 'was'

The One in JP3 Was A Hybrid

The real Spinosaurus had four legs, so I think the one in Jurassic Park III is actually a hybrid dinosaur. Who agrees with me?

By Misry6.

That's still being disputed due to those findings actually belonging to Sigilmassasaurus.

"*Sam Neill is 6ft tall. Using his height it can be determined that the Isla Sorna spiked Perimeter fences are 24+ft tall. Spinosaurus is shown being clearly the same height as the top bar of the spiked Perimeter fence as he is busting through it. The Animatronic for the Spinosaurus is also 45 feet long from Snout, to only the base of the tail(since no tail was made for it) Verifying Stan Winston Studios claims that the Spinosaurus is the largest theropod they ever made and introduced into the JP Franshise in all measurements."

Spinosaurus size

I'm a bit confused as to why the Spinosaurus' size is listed as a range rather than a singular number. It's official JP3-given size is correct, but the 15 meters length isn't, at least not for the movie animal. This is a Jurassic Park wiki, which I thought meant it would talk about the InGen dinosaurs, not the real life dinosaurs. The Jurassic World Dinosaur Field Guide is talking about the real life dinosaurs as it was written by two professional paleontologists; it's not the usual Jurassic Park/World-related material that's describing the animals InGen made.

KamikazePyro (talk) 20:26, September 8, 2018 (UTC)

Adding a trivia section?

If you watch the special features on the Jurassic Park 3 DVD, there are quite a few interesting tidbits that the crew mention. For example, it was said that at one point, they had the Spinosaurus running at 37 miles per hour but ultimately decided to put it down to 26-27. I think that's something worth knowing for the in-universe animal.
