    I found this in southeast Alabama in Houston county, it appears to be some bi valve fossils and others?. Please let me know if you can identify any of the fossils and the time period. Also the composition of the rock?

    Thanks!

    I think this is a chunk of dolomite, possibly from the Eocene Avon Park Formation. The molds/impressions seem to mostly be bivalves, but the second photo you posted looks like a partial echinoid (sea urchin). I don’t know the invertebrates well enough to give you any species names.

    Honestly, some parts of it look like a limestone or dolomite and other parts of it look like chert. It may not be from the Avon Park Formation, but it could be from a unit that is the same age in Alabama. This website mentions the “Claiborn/Jackson Group” which include “fossiliferous chert and limestone boulders”. https://mrdata.usgs.gov/geology/state/fips-unit.php?code=f01069https://mrdata.usgs.gov/geology/state/fips-unit.php?code=f01069
