shower fossil

Empty or used items left in a shower or bath.

I went to wash my hair and picked up two shower fossils before I found a shampoo bottle that had anything in it.

snowpocalypse fossil

Any missing item found after all the snow from the winter of 2010 has melted away.

This spring I hope I don't run across a snowpocalypse fossil of my missing lab rat.
