Lithology and environment
Primary lithology: | gray argillaceous "limestone" |
Lithology description: ... the Four Mile Dam Limestone contains a lower unit of dark gray, slightly argillaceous, coral biomicrite of unknown thickness and an upper unit of beige, crinoidal biosparite up to 4 feet thick. The upper unit is a small, crudely lenticular, crinoidal debris bank (Tyler, J. H., unpublished Ph.D. thesis, University of Michigan, 1963) which contains a rich and varied fauna with numerous species of gastropods, most of which have not been reported from correlative Centerfieldian units elsewhere. | |
Environment: | carbonate indet. |
Taphonomy
Size of fossils: | macrofossils |
