The source of #paleozoic (hemi-) #pelagic calcareous #mud (before the rise modern pelagic calcifiers) has been bugging me, again, recently.
I have seen arguments for calcification of #cyanobacterial filaments, calcareous #dinoflagellates, breakdown of thin-walled fossils, and I'm not negating #abiotic sources.Does anyone have any thoughts on the topic?
