Sedimentary rock often contains fossils because it is formed differently. It consists of sandstone, limestone, or shale that was once mud or sand in which the bodies of dead animals settled.

Nearly 100 m of shale lie below this fossiliferous interval in the Burgess Shale Formation. Assuming 40% post-depositional compaction of strata below the Phyllopod Bed, a conservative estimate for minimum water depth at the time of deposition would be approximately 100 m, essentially the lower limit of the effective photic zone.
