Geologic Time / Geological Eras Booklet / Cheat Sheet
My daughter is studying the geological eras at school (in 3rd grade - something I find quite fascinating), so I made her this booklet (meant to be folded into an A5 size booklet), which can be quite handy. The website I got the information from - https://sites.google.com/site/paleoplant/geologic-periods - has a wealth of useful information about the different eras and periods. I removed the ages in their list when making this booklet though, as they don't seem to study the different periods and epochs to that depth, so too much information, basically.
Here's the link to our booklet: http://ronny.ager-wick.com/6d3e7726/Geologic Time Booklet.pdf
