Lithology and environment
| Primary lithology: | gray,white silty,sandy marl |
| Includes fossils? | Y |
| Lithology description: The Caloosahatchee marl consists predominantly of shells, sand, and silt. Fresh unweathered exposures are generally pale cream-colored to light gray, although green clay marls have been included in the formation. The sand and shell variations of the Caloosahatchee marl can be separated from the marine formations of Pleistocene age only by identification of the mollusk faunas. | |
| Environment: | marine indet. |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | mesofossils |
Collection methods and comments
