The scale is divided into eons, era, periods, and epochs. An . Eon, billions of years ago, is divided by the . Cambrian boundary. when the variety of life forms exploded. An . Era. includes mass extinctions that mark the boundaries between eras. A . Period. includes blocks of time when a unique rock series was laid down. Fossils

The timescale is divided up into eons, eras, periods, epochs and ages. There are three eons – the most recent of which is the Phanerozoic. The Phanerozoic eon extends from the present to 545 millions of years ago (mya) and is divided into three eras: Paleozoic, Mesozoic and Cenozoic.

Title of item (5 words)
eras are divided into periods. periods can be further divided into epochs. Major information found on the geologic time scale includes: Precambrian is the name given to the earliest span of time in Earth history. Geologists divide the time between Precambrian and the present into three long units called eras (Paleozoic, Mesozoic, Cenozoic).

Notes on Diversity of Life, Fossils and Geologic Time
The Geologic Time Scale is accurately reflected throughout the project. Correct dates are given for Eras, Periods and Epochs. Fossils are correctly identified with their names and appropriate time. The Geologic Time Scale is accurately reflected throughout the project with few mistakes. Mostly correct dates are given for Eras, Periods and Epochs.

Contrasting several dating techniques chronicling Earth’s history to produce a geologic Time Scale. Geologic Time Scale- divided into Eons, Eras, Periods, and Epoches. Phanerozoic Eon (evidence of life began) divided into three eras. Paleozoic (ancient life) dominated by marine invertebrates. Mesozoic (middle life) dominated by reptiles

773 Each era is divided into smaller units called periods. 774 The changing fossil record also played an important part in establishing each of the periods. 775 Periods may be divided into epochs. Seven epochs are names for the periods of the Cenozoic era. 776 The epochs of other periods usually are just termed early, middle, and late.

Geologic Time Scale (GTS) Eons, Eras, Periods, Epochs
The Earth’s years have been marked by geologic, environmental, and biological changes. Earth’s history is broken into large divisions called eons then eras, periods, and epochs. These categories help geologist better understand Earth’s long history. In this project you are going to take a closer look at one small part of Earth’s long ...
