Crystalized Welks (W2)
Notes specific to this specimen: Fossil welks are much rarer than the clams found at Rucks Pit and most of them have no crystals. But, when you do find a nice crystal-line specimen, there’s nothing like it in the world! This is a single welk with a natural opening on its dorsal (top) allowing you to see the crystal lining of the shell and the gray sparite “floor” that was the sediment which partially filled the shell after the animal had died. Very unusual.
SIZE: 4″
NAME: Mercenaria permagna
AGE: Pleistocene 2 million years
UNIT: Nashua Formation

Rainbow Stromatolite (RS1)
Notes specific to this specimen: This is one of the original discovery pieces, collected by us in August 2025. It is characteristic of all the variety of colors found in this site. We’ve never seen such a variety of colors of stromatolite from a single site. It reminded us of all the colors of Arizona petrified wood – known as “Rainbow Wood” – and this became the source for our naming this new discovery “Rainbow Stromatolite”.

Cerdito Prospect Rift Crystals (CP2)
Notes specific to this specimen: Incredible combination of small clear quartz crystals with purple fluorite crystals over top of botryoidal green fluorite. Nice standup piece has sawn-flat bottom and back showing the dynamic cracks and infilling produced by the North American Midcontinent Rift which happened about 1.1 billion years ago.  Because of the fluorite, it fluoresces very strong purple/blue.
Documentation: This authentic mineral specimen comes with a Certificate of Authenticity and Origin.
