  • Handmade

A handy tool for students, professionals, and enthusiasts of the Earth sciences, use this bookmark as a reference when reading scientific literature -- or for those times when you just need to step out of the present and get a little perspective.

This bookmark shows the divisions of geologic time to scale, without distorting the relative duration of each division.

The front side breaks down the eons and eras of Earth's history from the present back to coalescing cloud of dust. The reverse side is a close-up of the most recent eon of Earth time (the Phanerozoic) zoomed down into eras, periods, and epochs.

Pair it with our Layers of the Earth Bookmark to make a veritable travel reference guide.

Water and tear resistant coating makes this bookmark durable and ready for fieldwork.

This product is printed, packed, and shipped from New York, USA using all recyclable paper packaging materials.

Product Specs:
Size: 2" x 8"

Bookmark is great! I needed it for my geology field book and while it's big it's perfect for helping me remember events. I definitely recommend this product.

Very cute!! Will be very helpful, for remembering the geologic time scale is one of the hardest things for me to do, so having a mini timescale on me at all times will make things so much easier!!
