Fossil Friday!

I encountered this week's fossil at the AGU conference in San Francisco.  I love this peculiar specimen!  Is it a plant?  A seed?  An animal?  A fungus? Can you guess which era it dates from? 

When you take a good look at it, the answer is so obvious it might sting!  As always, the first person to identify it wins bragging rights for the week!
