Here we have a rugose coral (likely Heliophyllum sp.) with numerous strings of the bryozoan Hederella filliformis. The two fossils contrast against each other well with the coral partially replaced with Quartz while the Hederella is still Calcite. This fossil was found in the Centerfield mbr. of the Ludlowville formation (Devonian, Givetian stage) near East Bethany, New York.
