And you thought the Green River sandstone beds only produced fish and palm fossils, eh? Well, I did. I personally never realized that the TYPE LOCALITY for this rare sodium/calcium carbonate was in Wyoming, before now. This specimen is exceptionally rich with gemmy shortite crystals embedded in the sandstone, to 1 cm in size. This is rather large for the species, and for specimens from this locality, if what I see on MINDAT is any indication.
