Dinosaur Bones (D4)
Notes specific to this specimen: This is a distal manus digit (“finger”) bone of Edmontosaurus. In vertebrates, the ends of the front appendages are called the “manus” (aka hand) while the back are called the “pes” (aka foot). The fine detail on the bone surface is remarkably well preserved. This piece has a small amount of reconstruction as shown in the dark paleoclay area.

Iron Stromatolites (ME5)
Notes specific to this specimen: Beautiful deep red agatization in these colonies attest to the classic origin of this specimen as being from the old Mary Ellen Mine in Biwabik, Minnesota, the type locality for the Biwabik Iron Formation. Notice the off-set angle of the growth pattern in this piece. This is attributed to constant water currents in the area where these colonies were growing.

Crystalized Welks (W3)
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! Here we have a nice matrix specimen with a natural opening on the side of the shell exposing gemmy dog-tooth calcite crystals. They don’t get much better than this!

Sudbury Impactite (2)
Notes specific to this specimen:
You’ve never seen this before! Why? Because we are the only source for it. These striking Sudbury specimens are cut to reveal the lustrous nickel and copper ore crystals scattered across its dark magmatic matrix. The flashy metallic patches catch the light beautifully, highlighting this classic mega-impact site whose resulting nickel–copper ore made Sudbury world-famous. A rare and powerful authentic piece of Canadian geology from 1.8 billion years ago.We are offering only a very limited number of specimens of this material. Most will be in the form of obelisks because they show off the mineralization patterns very clearly. At present we are offering only two different size obelisks. This is the larger one. The photos here are typical of this size. But you may not get this exact piece! Please keep in mind there is variation from piece to piece and the one you get may differ slightly from what is seen here. However, these photos are a good representation of what you can expect. Of course, as always, we guarantee your satisfaction or your money back.

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”.
