T-rex theory gets challenge by a fossil.

The T. Rex theory gets called out and challenged by a... fossil. The article was called "Fossil Find Challenges Theories on T. Rex" I read was in the New York Times. It was all about how the theory is getting challenged by something not alive. I wonder how that will do. The theory is “about the evolution of T. rex, which was about 5 times longer and almost 100 times heavier.” There was another predator before the T. rex who was roughly nine feet in length. But it only weighed 150 lbs. It was said in the article to live close to 35 million years before our “king of the dinosaurs” even walked on Earth. It was estimated to live 125 million years ago. But 65 million years ago the whole group became extinct. “The thought was these signature Tyrannosaur features evolved as a consequence of large body size,” Stephen L. Brusatte exclaimed. Then how’d did they become bigger than there so called ancestors? Wouldn’t that mean they would have to grow their skeleton to fit closer to the skeleton of the massive T. Rex. The “ancestors” of the T. Rex was called Raptorex. Well like people say “how could something so ‘small’ cause something so big?”
