This last week, I gave you a tricky fossil with the most basic of questions: was it animal, vegetable or mineral? Well, obviously mineral at this point, but when it was once alive, this little puffball was actually a now-extinct stingray!

This Heliobatis sp. was found in the Green River Formation in Wyoming. It dates back to the Eocene, 58-36 million years ago.

Kudos to those who guessed it! You get bragging rights for this week and next week, since this fossil lady is going on a much-needed vacation. 

We'll see you in the new year!
