Summary Introduction
To review:
The event that has occurred 66 million years ago and state its time of occurrence if the graph is compared to a clock starting at noon.
Introduction:
The Phanerozoic eon is a geologic eon in which abundant animal and plant life existed. It includes 541 million years till the present. In the graph, the Phanerozoic eon is shown and various other eras are represented. The extinction was observed in the K–Pg (Cretaceous–Paleogene) boundary, which was 66 million years ago. The given graph shows the overview of the events that occurred 180 million years ago representing the time range of selection of theropod dinosaurs.
