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”.

Iron Stromatolites (ME3)
Notes specific to this specimen: Rare white colonies with dark banded growth rings. Some have branchings. Specimen found in 1990s at the old Mary Ellen Mine in Biwabik, Minnesota, the type locality for the Biwabik Iron Formation. Notice the silvery spots of concentrated iron between the colonies.

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.

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.
