The disappearance of dinosaurs - Artist view - Tylosaur and KT Event - Artist view - Impact of the asteroid responsible for the disappearance of dinosaurs about 65 million years ago. In the foreground, a tylosaurus, a large carnivorous marine lezard. The very end of the Mesozoic is marked by evidence of a devastating asteroid impact 65 million years ago, which is termed the KT event, referring to the Cretaceous (K) -Tertiary (T) transition. This impact likely contributed to the demise of the dinosaurs, although recent findings call into question how decisive the blow actually was. In this image, a huge tylosaur, a relative of today's varanid lizards such as the Komodo dragon, faces its last few minutes of existence in a Texas lagoon. Over the horizon looms the rising ejecta from the KT impact, which occurred in what is today the Yucatan
