White Smoker - Extremely Rare!
This particular type of "white smoker" is from a preserved freshwater vent from ancient Lake Gosiute, the Green River Eocene, Wyoming. Lake Gosiute is roughly 50 million years old. The stromatolite Chlorellopsis coloniata Reis grew in the lake in nearly half a dozen forms and shapes from brain like appearances to a flat coco brown mat algae form.
The white smoker form grew and flourished around a fresh water vent in a lake saturated with a very high lime and alkaline content. The lake also had saturated waste from the prolific stromatolites. The stromatolites tolerate a very high pH but prefer a more neutral habitat to thrive in.
With a closer inspection some "smokers" will have ostracodes preserved in them, and will exhibit calcite crystals. These crystals were the last of the minerals to come out of suspension as the lake dried up and fossilized in the process.
This "white smoker" came from a fossil fish mortality zone where the fish hung on until the water became unlivable.
