Jurassic Park Three was wrong. Spino could not kill T. Rex. Why did it in the first place? Fans wanted something new, and now that they got it, the facts are getting twisted with the fiction.
Who was stronger? Tyrannosaurus Rex had more powerful legs, that could run and withstand pressures. They were much stronger than those of Spinosaurus legs. T. Rex had a much stronger neck. It's muscles were two feet thick; enough to lift up a large hippo and toss it. It's powerful jaws were five feet long, armed with over fifty sharp, serrated teeth that were solid and could crunch right through muscles and bones. The bite force of Rex was over 12,000 pounds per square inch, and this wasn't the mouth of a slow, weak scavenger.
Spinosaurus had thin jaws that were weaker, with straight, hollow teeth with no serrations or curves. The teeth couldn't tear flesh, or absorb shock and pressure given off by prey. They were made to trap fish.
Spinosaurus faster and more agile? I don't think so! Spino had a heavy sail on him, granting him a slow top speed, not much faster than that of a human. In fact, it would have to stand on all fours to support all that weight on land. Therefore, it could not use its claws for fighting, and much less break a neck with them.
First, SPINO HAS NO THUMBS!!!!IT CAN'T TWIST A NECK! ALSO T. REX HAS MUSCLE TOO THICK AND A BONE MEANT JUST TO KEEP THE NECK FROM TWISTING MAKING BREAKING A NECK IMPOSSIBLE!
Spino if it fell would land on the sail and break its spine. T. Rex could head butt with its powerful head, and one push could kill it. Even if the Spino somehow didn't break its spine it still needed time to get up and Rex would just go ahead and finish the competition!
We know Rex was faster because it had a muscle running from its tail to its thigh to increase speed. This could make it run over than twenty five mph! THAT'S NEARLY TWO TIMES FASTER THAN SPINO!!
ALSO SPINO MAY BE BIGGER BUT IT ISN'T BETTER. IT WEIGHED 6 TONS, AND REX WEIGHED SEVEN! ALL REX HAD TO DO WAS STEP ON IT. SPINOS SKULL WAS PATHETICALLY WEAK COMPARED TO REX, AND ALL THIS PROOF SUGGESTS T. REX COULD KILL SPINOSAURUS AEGIPTICUS EIGHTY PERCENT OF THE TIME!!
