There is nothing on the planet older than rocks and minerals. As a matter of fact they are bits of the planet itself. All of them formed back in the beginning of it all when the Earth had formed itself out of the swirling mass of space and star stuff. We have just stocked a great geologist's cache of mineral, rock and fossil specimens. Quartz, Calcite, Amethyst, Petrified wood, Galena were all formed as the planet was coming of age. And we also have fossils of of Ammonite and Trilobite, some of the earliest life on our fledgling blue planet. Hold these in your hand and marvel at time. Own a piece of the planet and appreciate all it has given us.
