I've blogged before about Protodouvillina inaequistriata specimens from the Centerfield member of the Ludlowville formation in New York in a prior post. Today I'm showing off a silicified specimen that I found in the dissolved remains of some limestone from the same locality. It is in great condition, has both valves and an interesting color pattern. I think the pattern is related to how much of the original shell was actually replaced with quartz. The shell also has some very nice looking "Beekite" rings
As I mentioned above, this specimen has been replaced with quartz and I dissolved it from a limestone block using dilute Hydrochloric Acid. It comes from the Centerfield member of the Ludlowville formation (Devonian, Givetian stage) near East Bethany, NY.
