Callianassid shrimp in Bahía La Choya, Sonora, Mexico, overturn the sediment in theinner flats at an average rate of 0.56 m/m/year. Elasmobranch rays overturn the sediment in themidflats at an average rate of 1 .Ol m/m/year. Resin castings indicate that the shrimp are capable ofburrowing to a depth of at least 1.15 m and, where present, can completely rework this interval inBahía La Choya in two years.

Reworking rates arehigh enough to preclude the preservation of most physical sedimentary structures under normal conditions.Only large-scale sedimentary structures or those buried deeply and rapidly are likely to escapereworking. Rates of biogenic sedimentation by callianassid shrimp are high enough to generate subsurfaceshell beds.
