By Nature Gallery specializes in the very finest rare fossils, minerals and related natural pieces available in the world. In addition to museum-quality pieces for collectors, we provide fine natural decorative pieces for the office or home and fine jewelry as well. We exclusively offer authentic specimens, never reproductions. The pieces we have carried and sold include large woolly mammoth tusks, dinosaur skulls, dinosaur teeth and bones, a complete giant ground sloth, a complete cave bear, pterosaur fossils, spectacular crinoids, ichthyosaurs, fossil palm fronds, fossil fish, stingrays and turtles. Beautiful large geodes of amethyst and citrine, framed insects and butterflies and amazing petrified wood tables also grace our galleries.
