A screenshot of a Smithsonian post. There is a picture of a fossil crab partially extracted from the surrounding rock. 2 little barnacles on its shell are also fossilized. The text says: This crab has never had to log into outlook at 8 am on a Monday morning. Crabs and other fossils are often found at the center of hardened spheres of rock known as concretions.
Cool crab but how do they know what time it logged in to Outlook?
Geologic record? Pardon, if you need me, I'm gonna settle down into this lovely muck for a while.
