Trilobites are ancient marine creatures who lived 400 - 500 million years ago. These hard-shelled, segmented creatures grew in various sizes from just three millimeters long to a length of 70 centimeters. These particular specimens were collected by my father and I in a remote region of Utah and are believed to help overcome fears, act with courage, and speak truth. Trilobite fossils are also thought to aid in transformation and overcoming difficult situations.
