- The largest and most deadly of all Mass Extinctions in the history of Earth came at the end of the Period, when only 5% of the existing species survived. Nobody knows exactly what caused this event, so it remains a mystery to this day.

- why is it not 55-34; Eocene if the Eocene period was 55 million - 34 million years ago as opposed to the Paleocene which was 65 million - 55 million years ago?The eon comprising the Cambrian period up to the present is called the (1). It is divided into three eras: Paleozoic, Mesozoic, and Cenozoic. The Paleozoic era, first (2) appeared. Finally, the Cenozoic era is where (3), flourished, lasting up to this day.After the Great Dying, we enter the Era which covers the evolutionary history of the dinosaurs up until they go extinct. Cambrian O Mesozoic Paleozoic O Cenozoic
- The Precambrian is characterized by several major evolutionary milestones. Which of the following is a significant event that occurred during this time? The diversification of flowering plants The first appearance of dinosaurs The first appearance of photosynthetic organisms A mass extinction caused by a meteorite impact.It has been suggested that the current time should be made into a different period. In other words, it should not have been part of the Holocene period due to the extreme changes man has made to the earth. If you were a scientist tasked to give a name to the period of today what name would you give it and why?The “age of fishes”, which began with the Cambrian Period (about 541 million years ago), and ended with the Permian/Triassic extinction event (about 252 million years ago), is also known as: the Mesozoic Era the “age of birds and mammals” the Cenozoic Era the “age of reptiles” the Paleozoic Era
