Factors controlling upper Jurassic ammonite assemblages in north central Mexico
Lower Kimmeridgian to Lower Tithonian (Upper Jurassic) sections studied at Sierra de Palotes (Durango) and Sierra de Catorce (San Luis Potosi), Mexico, show low-energ deposits in which the composition of fossil macroinvertebrate assemblages, including megabenthos, reflects biostratinomic control.

| Sumario: | Lower Kimmeridgian to Lower Tithonian (Upper Jurassic) sections studied at Sierra de Palotes (Durango) and Sierra de Catorce (San Luis Potosi), Mexico, show low-energ deposits in which the composition of fossil macroinvertebrate assemblages, including megabenthos, reflects biostratinomic control. Monotonous siltstones provide continuous records of ammonite assemblages and reflect dominant deposition of shells in living areas |
