Are you looking for the most unusual birthday presents ever?

Prehistoric objects and fossils always get great reaction when they come on to the private sale market - the odder the better! This week a new paleontological oddity has made its way to auction: a coprolite, or piece of fossilized feces, that is allegedly the longest ever to go on sale.

The fossil is being auctioned by the I. M. Chait gallery in Los Angeles, California. It was uncovered in a formation in Washington State that dates back to the Miocene and Oligocene epochs, between 33 and 5 million years ago.

The auctioneers are expecting this one fossil to go for $8,000-$10,000.
