Count cells of modern & fossil leaves.  Help us track climate change over millions of years!

Fossil Atmospheres

If you're just starting on this project use 'Practice Count' to learn how to identify cell types and compare your answers to expert classifications in the field guide.  Next you have a choice of two levels to work on: 'Easier Count' or 'Stomatal count'. We need your help with both sets but Easier Count allows you to improve your skills while you count. Stomatal Count is great for  once you're feeling more confident and are ready to tackle tougher images.
