This table is not for pooping. It's for tea. But it is made of poop — specifically fossilized hunks of fish poop, encased in a crunchy shell of clay and rock. The fossilized poops — called coprolites, which is basically just fancy Latin for "fossilized poop" — are the spiny-looking bits in the center of each circular inlay on the table top. (Technically, the name translates as "dung stone".)
The table belonged, appropriately, to the Rev. William Buckland, the man who gave coprolites their fancy name and proved that they were, in fact, fossilized poops.
The table resides at England's Lyme Regis Museum. You can read more about Buckland's work and the details of the craftsmanship and restoration behind the table at their website. Earth Magazine also has a lovely article on coprolites, including important information that will help you distinguish between fossilized poop and stuff that just looks like fossilized poop.
