Dwarves' Earth Treasures: Mushroom Thundereggs from Indesonia, Asia


.	Dwarves' Earth Treasures Museum: "Mushroom Fossil" Thundereggs Indesonsia, Asia	.

I saw a dealer at Quartzite with those weathered agate cores that were mislabeled as petrified mushroom fossils and I was able to clear up with the dealer and the miner on the origins of those agates. The miner also a geologist dug them up in a heavily weathered clay bed that had beem widely mistakened as the ash beds. The so-called "Mushroom Fossils" agates are actually the weathered agate cores of the thundereggs which the rhyolite shells had been erodeda way leaving behind the characteristic cristobalite striations on the cores. The agates are generally dark colord and lacking in banding features and some came with good plume inclusions.
