Sulphur River Black Fossils

Recommended Posts

Fossils from the red sandstone layer in the North Sulphur River.  Ladonia, Texas.  Does anyone know why the fossils in this layer are black, or what mineral it is?

I'm told they are black because of phosphate replacement. I love the way the white sutures show so plainly on the Baculites when they are black instead of red.

Very nice. I agree with BobWill, those Baculites are fantastic looking with the white suture lines.
