The Timeline of Life 2019-20 Edition

Updated: Oct 15, 2019



The 2019-20 Edition of the ETC Timeline of Life has recently been released, and is the most accurate and up-to-date Timeline of Life on the market!


ETC created this timeline and continue to update it with information contributed by scientists in the Smithsonian Institute and Columbia University. Keeping true to our motto of "Total Montessori", each scientist was handpicked so that in addition to their degrees they also have Montessori credentials. 


What's New:


This new version has replaced the Pangea Globes with new and original work depicting detailed information about the continental drift. The globes are bigger and better curated. Accompanying the continental drift, ETC designers replaced the mountains from the previous version with actual pictures of the mountains being depicted. Knowing ETC, and the way they interconnect their curriculum it will be interesting to see how the new additions will play out.

What Remains:


This model continues to have the color lines to designate the various lineages making it easy for children to follow the evolutionary patterns that lead to modern animals. They have even made it easy to spot the Devonian explosion of plant life. Each lineage line is clearly marked along with detailed images that beautifully illustrate the originating events which lead to various evolutionary patterns such as the development of mammals. In addition, all major extinction events are clearly marked, and we have included all the glacial events, beginning with the two major ones that occurred during the Proterozoic Era.



Abundant information allows children to understand events that shaped the evolutionary process. Discover how the great glacial periods along with the great extinction events changed phyla and species. What sets our timelines apart is the interconnectivity and the consistency with other materials. Therefore, the pictures as well as the lineage lines are consistent with those students will find when using the Tree of Life (Cladistic model).


The working model of the timeline of life includes:

  • Two Timelines:Control with text and pictures

  • Mute with lines and background

  • Movable Pieces printed on transparent material

  • Labels

Dimensions: 18 in. x 9 ft.
