• Fossil Sand Dollar and Clam (KH3)

    These well-preserved clams and sand dollars lived in a shallow sea that covered the San Joaquin Valley for millions of years. During storms the animals became buried in sediments which preserved the shells. Under heat and pressure, the shells altered into calcite, yet preserved their fine detail. Later, due to movement of the nearby San Andreas fault, the whole area was uplifted, becoming the Kettleman Hills. The Hills became famous for its oil in the 1920s. But the oil has since played out and the land is returning to its former native environment. We’ve polished the primary shells to show their beauty and detail. Iron and petroleum color the shells. We have spent years mapping the Hills and are the only people who know where to find these unique fossils.
     

    NOTE: One large polished sand dollar with a great polished clam.An attractive and informative display card accompanies the specimen.

  • Iron Stromatolites (ME2)

    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. The mine shut down over 50 years ago. 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. *This specimen comes with a Certificate of Authenticity and Origin
