The Mount Stephen trilobite beds (UNSM locality 14s) are a series of fossil strata on Mount Stephen, British Columbia that contain exceptionally preserved fossil material. Part of the same stratigraphic unit as the Burgess Shale deposit, many non-mineralized parts (such as anomalocarid claws, sponges, and trilobite legs) are preserved; in addition, a high density of trilobite fossils is present.
