Coral Fossil

Recommended Posts

I found several pieces of coral in my back yard (small wooded area) and wondering what type this might be - it appears to have a lot of calcium or lime stone on top but in the crevices it is loaded with black specks.....I would appreciate any help

It's hard to tell what I'm looking at; maybe an overview picture with a size scale would help.

This might be heavily weathered limestone; the visible features are pretty random.

The specimen is not a coral, in fact I don't see anything organic about it. Corals don't just have a bunch of randomly sized featureless holes; the corallites are very regular in size and spacing, and they have internal features such as septa and spines.

I suspect the black thingies are lichen or algae growing on the surface. You could try and put some bleach on a small area. If the black spots disappear, they were probably some organism growing on the surface of the rock.

Here's a photo of one in my yard...found it near a hot spring in the Rockies near Cadomin, Alberta, east of Miette Hotsprings in Jasper National Park.

Mine was in wisconsin...several mile from any water

Away from any now, maybe, but this didn't come into being recently. :)
