Notes: The white shell is filled with calcite crystals which appears to have been an enhydro (water filled) agate clam belly. The reddish clam is totally fossilized.
This is beach combing 101 for sharing trophies found along the Pacific Coastline. Agates, jasper, petrified wood, 15 - 20 million year old marine fossils, to zeolites and more as found on Oregon's scenic beaches! This is brought to you as a continuation of my pocket guides Agates of the Oregon Coast and/or Agates of the Pacific Coast.
