In a paper published on April 1, 2011, scientists in China have discovered a dinosaur similar to the Tyrannosaurus Rex in size and features. This creature, called Zhuchengtyrannus Magnus was excavated from a mine. It is slightly smaller than its Tyrannosaur cousin but is still considered to be one of the largest carnivores to walk the planet.

The article What Killed the Dinosaurs? goes into an in-depth discussion of the different theories of the extinction of the dinosaurs. It looks at the competing theories and delves into the differences and the reasons why scientists believe the different theories. Almost every scientist believes that it was a culmination of events that led to the disappearance of the dinosaurs, but what events culminated is the origin of the differences.

This article discusses the history of the theories of the extinction of the dinosaurs including related evidence supporting the most prevalent theory of an asteroid impact. The article goes into in depth reasons why the asteroid impact is the most widely accepted hypothesis. It also discusses the history of the paleontologists that first suggested this theory.

The theory that an asteroid killed the dinosaurs is accepted by the majority of scientists. Here we see that not everyone believes this is the case. With recent scientific discoveries, it is now believed that the asteroid impact that occurred off the Yucatan peninsula possibly happened 300,000 years before the K-T extinction. If this is actually true then the cause of the extinction of the dinosaurs would have to be reevaluated.
