Next fossil I think is some sort of cystoid from the Waldron Shale. It has a four petal flower shape at its base? There are also five petal patterns on its surface. Needs cleaning with air abrasion to reveal better surface detail. Fossil is small at just over 1 cm long.
Indiana State Museum collection database has a Waldron Shale algae fossil specimen cataloged as a Receptaculites sp.
The fossil could be some sort of bryozoan in weird shape. Fossil is over 1 cm long.
