JP3 Spinosaurus Hypothesis

I (like the rest of you) am stoked about the JW updates, but something has been wracking my brain for a while, and I figured for my latest post (in a long time compared to many of you), I'd bring this up.

The lack of a confirmation on the JP3 Spinosaurus' sex has lead to it being listed as a male on some sites, and as a female on a few others.  Other sources just don't list it at all, because it has never been confirmed by anyone.

I believe I have the answer.  It was a female.

"Why do you think that?" the masses ask.

Well, she had to have hatched sometime before TLW.  InGen abandoned their facilities on Isla Sorna after the Nublar Incident, allowing the young dinosaurs on that island to grow up into adults and start breeding on their own.  Up until abandoning Sorna and Nublar, they were still using frog DNA from the same breed of frog to fill in the dinosaurs' genetic gaps.  And all dinosaurs that were hatched in the labs were born as females, because InGen wanted to control the population and prevent breeding.  That Spinosaurus was hatched in a lab before she was shipped off to Sorna to grow up a bit.

According to this site, sex change in animals only occurs if the ratio of males and females isn't in equilibrium any more.  Since the dinosaurs that were hatched in InGen's labs and stayed on Isla Sorna had that frog DNA in them, some were bound to change from female to male.  That explains why there's a breeding pair of T.rex and several packs of raptors consisting of males and females, among other species.  But with only one Spinosaurus, there couldn't have been an equilibrium to stray from, SINCE THERE WAS ONLY ONE!!  There would have been no need or desire for that ONE Spinosaurus to become male when there's no "potential" breeding partner.  

Therefore, she remained female for all of her time on Isla Sorna.

SHE destroyed the plane.  SHE killed that young male T.rex.  SHE smashed through the fence and failed to break through the wooden door of the building.  And SHE attacked the boat.

And she was (is) a beautiful creature.

Unless her/his mate is the one on display in Jurassic World. BADABOOM!!! Plot twist.

No but seriously; I want to know the back story behind that spino skeleton in Jurassic World.

Welll during early jp4 discussions... before everything went to developement hell, they were talking about how the spinosaaurus would be back and she be bigger and badder then before... So your theory is possible...

Hm. I never thought of it that way. There's a good chance for this, plus she isn't really the most colorful creature out there, and in birds, the males are the more colorful ones.

 

Also, how do we know the Spinosaurus bones are real?

True. It could just be an artificial display piece in Jurassic World meant to act as nothing more than symbolism for audiences watching the movie.

I don't think it really matters if the spino is male or female; the point is we would run at the sight of it, but it would be nice to know for technical reasons what Universal claims what sex it is.

Yes Sci-FiKing25, that question is worthy of being pondered.  I say no, because having valuable fossils worth a lot of money in the middle of a large square with tens of thousands of people is a result of poor judgment.  They could be replicas though, like in most museums.

But those bones are definitely NOT those of the JP3 Spinosaurus.  Those bones aren't big enough for a 13+ metre Spinosaurus, the sail extends too far up the neck/upper back, and it has a crest just above and between the eye sockets instead of 1 crest above each eye (which was inspired by Suchomimus because in the late 90's, nobody had a complete Spinosaurus skull yet).

Plain and simple, it couldn't have been her, so we shouldn't feel conflicted if the T.rex smashes it on her way to fight Indy.

Rexy vs JP3 Spino anyone?

Rex Fan 684

May-16-2015 1:41 PM

I see what you mean about the female thing. My understanding is that the Spinosaurus was a male because of it's aggressive, territorial nature and relatively dull colors. But that's technically not confirmed, just a leading theory.

Rex Fan, I heard that theory too, and the aggressive behaviour is the evidence to support the theory that this Spinosaurus was/is a male.  But it's easily countered with how aggressive certain female dinosaurs were in the whole franchise.  Rexy could have been just as aggressive, the raptors were were right up there, and Indominus rex will be the most insane animal we'll ever see in the franchise.  It can be argued that the Spinosaurus was more aggressive than any of those because how the animal followed everybody intentionally, but even the male T.rex from TLW while in San Diego wasn't that scary, more scared.  He didn't cause as much damage or act as savagely, so the correlation between gender and aggression is weak.  Yes, different species are used in the sample, only because there's nothing else to compare the Spinosaurus with.

Tyrannwright, I would not take that action.  Too many times in years past a T.rex vs Spinosaurus debate here resulted in chaos, and I wasn't even a part of it.  I knew enough to stay away from it, and all the real stuff has been said about it.  So everyone can think to themselves about it, but I will not be involved in any kind of a Spino vs T.rex debate here, much less make one myself.

It would be fun, sure, but it has been proven to get out of hand too many times.

Not a debate, a written story. I already know Rexy would win since she was much older and more powerful that the sub-adult that challanged the Spinosaurus.

^Please, let's not start this again. Nobody wants to know who would win, and I don't think anyone really cares anymore about that bloody fight.

As for the topic at hand, it is plausible the Spino is a female. I recall hearing that the crests, while misplaced, could have been used as a sexual ornament to attract potential mates, although they don't really look that suited for display to me (little brown stubs, not that striking). And like RexFan said, the dull coloration of Spinosaurus and the rather aggressive behavior stand out more than other examples; one being the Tyrannosaur buck from TLW.

Be yourself, for everyone else is taken.

Battra, those crests probably weren't main display structures.  They were too small to be on such a large creature.  They probably were there to help accent the individual's sex, like how a strong jaw line is more common in men than women.  The sail was the most likely to be a display structure, some recent piece of scientific literature (which was probably about the Spinosaurus' new reconstruction) said that temperature regulation was ruled out for nw because of a lack of blood vessel grooves or the presence of them (I can't remember which).

Stating that the animal's aggressive territoriality could mean that it was a male is reasonable, and I originally thought that too.  But because JP is more about genetic engineering with dinosaurs being its medium rather than dinosaurs only, I reject the hypothesis using aggression to determine its sex.  Modern animals' behaviours are known enough that most males are more aggressive, while other animals have the females being moreso, such as hyenas and harpy eagles, but since we don't know exactly what those geneticists did and what real dinosaurs did in their behaviour, genetics has to be the basis for my theory.

Not going to go into full detail, but I always considered it a boy. I always say he/him, but this is not because "he or him is more common"thing people have told me, infact he is one of few males in JP. But yeah unless we get a confirmation, I will say he/him.

And yes she/he is beautiful...A magnificent creature.

Sorry... :( 

I love both T-Rex and Spinosaurus so it has always been hard for me to pick a side...

Does this make you happy?

May-16-2015 8:55 PM

Don't worry JPCerato, Spinosaurus became my new favourite when I first saw JP3.  T.rex was and will always be my default favourite, but to a 7 year old dino fan, any theropod that can take down a T.rex is a big deal :P

It's interesting that you bring up the tendency to refer to dinosaurs as male, no matter what the sex is.  If the average person were to see an animal, let alone any of JP's dinosaurs, they'd first think of the animal as a "him", just because it doesn't look "girly".  Says a lot about our own sociology, especially since most of JP's dinosaurs are female and would those theropods would gladly eat us for lunch.  Just because something is big/scary/not "girly-looking", it's got to be a him because strength, size, and even "ugliness" are associated with men.  Really sexist when thinking in the context of gender sociology.

Even in Jurassic Park the novel, Dr Wu said "We tend to refer to some of them as male-such as the Tyrannosaurus rex; we all call it a 'him'-but in fact, they're all female.  And, believe me, they can't breed."

I know, I just meant the average joe would usually say he/him, I don't I refer to them a she/her in JP, the spino is really one of the onyl ones I say him/he (aside from the Bull/Buck and some raptors)

The Tyrannosaurus Buck was definitely just as aggressive, possibly as much as Rexy. It challenged the Bus, Police cars, and attacked a house. I chased and attacked any large item in its path. However, I believe Rexy MAY have been male, but that is beside the point. I believ that in JP, bothe genders are equally aggressive.

I always wondered that, any of the JP dinosaurs could maybe be males, The Big One or Rexy etc. unlikely but possible.

^ Well, that's a good point JPCerato, but like Alphadino65 stated in his/her post that actually caught our attention in order to bring us to this thread, if there is no potential mate that lived with Rexy, there would be no need to change sexes. This actually brings me to my next point...

Alphadino65, what evidence supports that the Spinosaurus we saw in JP/// was the ONLY individual that existed on the island? We only saw three Tyranosaurs in The Lost World: Jurassic Park, but there is no way that with how much the herbivores have reproduced that the carnivores, especially with so much prey available, couldn't and/or wouldn't do the same.

*Facepalm*

With the new skeleton, I'm not sure how capable Spinosaurus was anymore. Not to mention, the Spinosaurus was GOING to be the new therapod for the movie anyway. No matter how strong/weak, fast/slow, or large/small the Spinosaurus was, it was going to kill dear old Timmy the Tyrannosaur no matter what. Any therapod could've taken it's place, like the originaly planned Baryonyx, and the same thing would've happened, so we're left to ask ourselves, outside of this partly fictional universe, who REALLY would've won? This is, of course, a debate for another day, but it's just something to think about. Food for thought, if you will.
