Notes
Limonitized steinkern (originally siderite) in pedicle view and external mold of brachial valve.
Diagenesis
Absence of compression in the sample indicates mineralization prior to sediment compaction. Organic decay released carbon dioxide, reacting as carbonic acid with ferrous-ion-enriched pore water to form siderite, subsequently altered into limonite.
