Volcanic Bomb (EB12)
Notes specific to this specimen: Large, rare, combination fusiform bomb. This is the result of three individual magma projectiles running into each other in flight. In this case the merge of these three individuals was early in the ejection event but after the individual projectiles had started acquiring their own individual character. The combination of these three bombs resulted in one very large cigar-shaped bomb which acquired it’s own form which dominated the final shape before falling back to Earth.

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.
