“Alison’s Timeline of Life now has a number of important features, including the five great extinctions, the Cambrian biota, the Devonian explosion of plant life, and illustrations of the synapsid lineage, which led to mammals. I was pleased to help with the hard work of updating this valuable learning material for Montessori elementary classrooms. – Priscilla Spears, Ph.D.”

This comprehensive timeline of life is a great resource to have in your classroom. It features over 142 visually appealing pictures and text that is simple and easy for your children to understand. All the pictures are hand painted and detailed to give a beautiful and attractive look to the timeline.

Timeline ranges from the Cambrian Period to Cenozoic Era. It is printed on synthetic paper that will not tear or curl when rolled for storage. (Research cards, mute chart, and decals are not included.)
