Abstract

Some 65.5 million years ago, there was a mass extinction event which is known as the Cretaceous–Tertiary or KT event. This article explains the hypotheses that have been posed about the cause of this extinction, in particular a meteorite that collided with the Earth, yet this theory still raises many questions. The KT extinction caused the disappearance of many, but not all species, which suggests that the case is still far from being resolved.
