Due to the Covid-19 emergency, the Fossil Atmospheres project will not be accepting any Ginkgo leaf samples for the 2020 collection season. Happily, your amazing response to the 2019 collection season means we have many samples to analyze and that the science of our project can continue. Thank you all so much for your continued interest in Fossil Atmospheres and please consider visiting our Zooniverse site to help with leaf cell analysis.
