Summary
USNM_35227 (pictured) and USNM_35225: Multiple trilobite fragments are fossilized in the same rock, these are commonly known as hash beds. "Hash" is an indicator of a near-shore environment, where waves could have broken apart trilobite exoskeletons and molts then re-deposited them. These particular “hash” beds are composed of trilobites Wilbernia walcotti (USNM 35227) and Idahoia wyomingensis (USNM 35225). Both samples were collected during the early 1900’s in the northern region of Yellowstone National Park, from an exposed section of the Upper Cambrian (~500 million years ago) Snowy Range Formation.;
