T-Rex VS. Spinosaurus - The Reality of Jurassic Park III.mpg

Ever since I saw Jurassic Park III, I've wanted to do this video. There is NO WAY Spinosaurus would've won that fight against T-Rex. So, I went to Isla Sorna to find out what REALLY would've happened! This is a project I made for my sixth grade film-making students. It took me about a month to put together and for what I had to work with, I think it came out pretty well. Note from Creator Many viewers have been criticizing this video (some more colorfully than others) on its scientific accuracy. I want to make perfectly clear of one thing: THIS IS MY OPINION. There is no way we can conclusively say who would be the victor of this fight. Spino and T-Rex lived on two separate continents (Africa and North America), at two different time periods (Middle and Late Cretaceous), and ate much different things (Piscivore and Carnivore). However, I simply didn't like what they did in JP III. Here are my facts to support my video: 1) Teeth - T-Rex had the largest and thickest teeth of any land predator. They were thick D-shaped teeth, sometimes called "banana teeth" with serrations on both the trailing and leading edge. Spino's teeth lacked serrations and were hollow. Carcharodontosaurus and Giganotosaurus had thin teeth, perfect for slicing and tearing meat, but not for crushing, which was the main goal of the T-Rex. It wanted to grab in its jaws, crush in a single bite, then shake it until it was dead. Spinosaurus has been proven to be a fish eater time and again, so it would not be capable of the carnage seen in JP III. However, I will say that the film was accurate about one thing: the scene in which Spinosaurus rose from the water to attack the boat. In that regard, the behavior of Spinosaurus is plausible. 2) Mouth Shape - T-Rex had a rounded snout, similar to an ice cream scoop, to rip enormous chunks of meat off prey items. In one bite, it is estimated to rip approximately 300 - 500 lbs. of meat. Spino's jaws were narrow and long, excellent for quick fish traps, but not for attacking or ripping meat off large animals. Giganotosaurus and Carcharodontosaurus had triangular jaws that came to a point. Nasty, but not as large as T-Rex, meaning that they could rush in and take quick chunks of meat off of prey to wear it down. When compared to Spinosaurus, Tyrannosaurus Rex had the larger jaws for taking down larger prey. On the other hand, Spinosaurus had a quick snap-trap set of jaws for snapping at fish, incapable of tackling anything larger. 3) Bite Forces - Given the difficulty to measure, this is subject of debate, but with the advent of mapping muscles on skulls, it's estimated that T-Rex had enough force behind its jaws to bite with over 3,000 lbs. of force, the largest bite forces measured on a land animal. It's skull was also adapted in such a way to handle excessive forces and distribute those forces so that it could maintain the bite. Although it hasn't been fully measured yet, given the sizes and shapes of the other large predators mentioned, they couldn't come close to the same numbers as T-Rex. We do know, however, that relatives of Giganotosaurus and Carcharodontosaurus, like Allosaurus, were capable of extending their jaws much wider than other predators. Again, perfect for grabbing fast bites and puncturing with tremendous forces, but nothing comparable of T-Rex. Based on the relatives of Spinosaurus, such as Suchomimus and Baryonyx, the bite forces could be estimated to be enough to snap at a fish and clamp it in its jaws, but nothing close to T-Rex, given the differences in how they hunted. So, in summary: Teeth: Winner - T-Rex Jaw Shape: Winner - T-Rex Bite Forces: Winner - T-Rex Prey: Winner - T-Rex (Triceratops + Duck-Bills) Although nobody can ever say conclusively, "who would win," those were my arguments for making the video. If you plan on leaving a comment, please do so, but don't expect me or anybody else to take you seriously if you don't plan on supporting your opinion with evidence. All footage is owned by Universal Pictures and was simply used to prove a point. This film was made by a fan of dinosaurs and the Jurassic Park films.
