The name “trilobite” is derived from the three longitudinal divisions, or lobes, of the trilobite body. What is often referred to as 100% natural and authentic in trilobite collecting - is a trilobite found in a cross section (the only way to find complete specimens is by splitting rocks), prepared out of the rock (matrix) and all parts glued together (and so a crack running through the trilobite and matrix is therefore a good sign of authenticity).Cambrian Period, earliest time division of the Paleozoic Era and Phanerozoic Eon, lasting from 538.8 million to 485.4 million years ago.
