125 Million Years, Down the Tubes

In Utah this past Thanksgiving, we went to a dinosaur museum, where Colby bought a sand-dollar fossil.  A 125 million year old fossil.  I went to school today and cleaned out Colby's desk, where I found the fossil in 5 pieces.  It survives 125 million years, facing all that nature can throw at it, and then lasts two months with my seven year old son.  Yeah.  That's about right.
