Spinosaurus: Bigger Doesn't Mean Badder

Hey Internet, this is MovieDragon009 back again with another blog post.
To start off, I just want to emphasize how freakin' awesome dinosaurs are to me. I was mad about dinosaurs when I was in kindergarten, and even as an adult I get excited whenever some news about dinosaurs comes up, especially if it redefines how we look at them. And how could you not get excited about dinosaurs? Even if you're one of those people for whom those colossal bones at the museum are just a bunch of bones, there's no denying the awe that comes from within when you come face to face with the reconstruction of such real world monsters, providing a glimpse into a world that, admittedly, none of us understand quite fully (and we may never will). With that said, it's easy to imagine how terrifying and awesome it would be to see dinosaurs alive again...and go head to head to see who would trump the other in a fight to the death.
 Yeah, we as a species should really reconsider what we consider to be entertaining.
 With that said, I now bring up one of the most heatedly debated topics in history. When this event first came out, it deeply divided the fanbase of the movie that portrayed it, resulting in flamewars that continue to this very day, tearing apart friendships and deeply disappointing hosts of people.
 I am of course talking about the match between the generational fan favorite Tyrannosaurus Rex and the newcomer burdened with a jack-ton of marketing potential, Spinosaurus.
The logistics of the battle are already screwed up enough; anyone who's seen the movie knows about how that particular match ended, with Spino somehow managing to grab the Rex by the head and use its larger arms to break his neck. This is in spite of the fact that Rex got in the first hit and, as anyone with any knowledge of the tyrant king will know, also the killing blow; the jaws of the Tyrannosaurus were powerful enough to crush bone, a tactic that it would have used regularly against its prey. That first bite on the neck alone should have been powerful enough to put an end to the Spinosaurus' reign of psychotic terror (yes of course the Spinosaurus was insane; why else would it try to go after a bunch of random humans like a serial killer?). The fact that the Spinosaurus won in the end with such a ridiculous tactic is clearly a marketing ploy to sell more Spinosaurus oriented merchandise to kids at the cost of a dinosaur who for years reigned as the king in the hearts of people across the world. But fans across the world consider the snap of the Rex's neck a vicious blow to their childhoods; even the Nostalgia Critic in his review of the movie was clearly hurt by the event, labeling the Spinosaurus a 'squiggly-jawed %@*$'.
I bring this up in light of recently published evidence regarding Spinosaurus; just in the past few years, with more and more bones coming to light, we have come to know that Spinosaurus was a piscivore, or fish-eater. Up until this past week, the common belief was that the big guy waded in water like an enormous stork, plucking gigantic sawfish with the help of pressure sensors in the tip of its snout. Sereno's discoveries, however, push the extent of this lifestyle to new levels; apparently, Spinosaurus is the first dinosaur to have pursued, at the very least, a semi-aquatic lifestyle, swimming in lakes and rivers like an enormous duck. You may have seen the new reconstructions of the skeleton; while the hind limbs seem a tad too small, the overall impression is of a dinosaur trying to be a crocodile...or the closest thing to a dragon we have ever found (look at that skeleton and tell me that you don't see a resemblance. To me, that is just so freakin' cool!). It's been all over the news on the internet, but while they have highlighted the unusual appearance of a dinosaur we only thought we knew, for some reason the headlines emphasize the fact that Spinosaurus was far larger than the T-Rex, bringing to mind that heartbreaking scene from Jurassic Park 3.
For some reason, in the eyes of journalists and the people at large, bigger ultimately means badder in dinosaur terms; in the past two decades alone, the headlines have emphasized this more often than I can imagine with the reveals of dinosaurs like Charcharodontosaurus, Giganotosaurus, and even the sauropod Dreadnoughtus attempting to put T-Rex to shame. I'm not going to argue with the fact that Spinosaurus and the afore-mentioned dinosaurs were indeed bigger, but badder? That's a pretty bold statement, especially when you take other factors into account.
What do we currently know about Spinosaurus? That it was a highly specialized fish-eater, possibly an experiment that could've brought about fully aquatic dinosaurs had the lineage been allowed to continue, that it was a contemporary with Charcharodontosaurus, which it outsized and quite likely clashed with when food supplies were low. However, this also includes the fact that its teeth were suited for grabbing, not tearing apart, it's cartilaginous fish prey, and that it also depended on said pressure sensors to detect its prey. In that regard, we do have to acknowledge its superior strength, but can't assume that Spinosaurus was particularly smart; who needs to be smart when you can detect fish with the tip of your snout?
Tyrannosaurus, on the other hand, is a completely different animal; all the evidence points to it being a fighter. It came armed with stereoscopic vision, thanks to it's eyes being positioned towards the front, like us humans. Theories also suggest that it could see further than hawks, had the best sense of smell in the animal kingdom, and was also fairly intelligent for a reptile. Another theory that I personally like is the theory that the T-Rex was a pack hunter; the younger, longer limbed juveniles chased prey like lionesses into the jaws of the adults. This would also include the factor that, quite possibly, the Tyrannosaur was a strategic thinker. And have I talked about bone-crushing jaws enough?
So, ignoring the fact that they were millions of years and continents away in real life, if you pit a Tyrannosaur against a Spinosaur, who do you think would win? Me, personally, my money's on the one who's got the tools and knows how to use them in a fight. Granted it depends on the setting; had they met at a lake, it's very possible that, like a crocodile against a lion, the Spinosaurus would have the upper hand (or claw?), but even then, you have to acknowledge what kind of animals they were. In my POV, the T-Rex was a 24/7 hunter, while the Spinosaurus, while larger and more powerful, was still a fisher.
To put it bluntly, bigger does not always mean badder.
