I've probed around in probably 50 quarries and banged on a couple of hundred road cuts across the United States in my life. Most limestone i've run across contain fossils to some extent. Some are solid fossil and some have sparse marine fauna, but there are always a few exceptions. You may want to read up on cold water "tufas" and hot water "travertines" (2 non-biogenic limestones). In fact, Brown's description of the waters depressurizing as they were expelled from the depths sounds alot like the scenario we see occurring at Yellowstones Mammoth Springs Travertine Deposits..
