The herbivorous dinosaurs that fed on these plants died, as did the carnivorous dinosaurs that fed on the herbivorous dinosaurs. The event is so striking that it signals a major turning point in Earth's history, marking the end of the geologic period known as the Cretaceous and the beginning of the Tertiary period. the era were.

Soft-bodied animals are well represented in these faunas. The Tertiary Period began about 66 million years ago with a mass extinction that 'clocked' the dinosaurs and ended when the ice ages of the Quaternary Period began, about 2.6 million years ago. In 1828, Charles Lyell incorporated a Tertiary Period into his own, far more detailed system of classification. As the period ends, dogs, cats and pigs become commonplace. It also began the Cambrian Period. The Cretaceous Period (145-66 mya) is one of the major divisions of the geologic timescale, reaching from the end of the Jurassic Period (i.e. The Cretaceous-Tertiary extinction event, which occurred approximately 65.5 million years ago (Ma), was a large-scale mass extinction of animal and plant species in a geologically short period of time.
