$84.00
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 superb large sand dollar and several clams. An attractive and informative display card accompanies the specimen.
SIZE: 6″x 3″x 4″
