These specimens were collected from the blast crater prior to the 1950s ban

This dust was created during tusk cutting and carving and we felt it should be salvaged and loved

Trilobite Fossils, Acastoides oddities FeO/MnO = 75-81These are real, complete, fossilized trilobites (Acastoides)! Trilobites were an extremely adaptive marine arthropod that first evolved roughly 521 million years ago and rapidly spread across the globe. They diversified into approximately 17,000 species and were one of history's most successful animals existing for over 270 million years before extinction!
