You know what your place is missing? Mammoth. This cross section of mammoth tooth exposes the inner structure and brings a little of the Pliocene into your home. Unless the boffins get their skates on with cloning a mammoth, this may be the closest you ever get to the real thing. Mammoths, like modern elephants, were grazers and their teeth were what is known as hypsodont, acting like a pestle and mortar for their tough diet. This section of mammoth tooth can be yours for a mere $20, delivered to you in a lovely presentation box, but if you're feeling flush, you could also go for this incredible female mammoth tusk for a cool $7,200. You should also consider sorting out your spending priorities.
