Mineral Description
healing crystals

These fossil were mined by Kidz Rocks from the Topanga Formation of Southern California. The deposit is no longer yielding these nice specimens so these may be the last from that same location. You will receive one fossil that is 2 inch to 3 inches long by about 2 inches wide.

Bulk Purchase Specimen
You are buying one rock. You will receive one rock like the ones in the photographs, not the exact rocks shown. Photographing and listing every crystal separately adds a lot in labor costs. We pass that savings on to you with lower prices and higher quality than the competition.

Mollusks are an amazingly diverse group of animals that live in a wide variety of environments. They can be found inhabiting trees, gardens, freshwater ponds and streams, estuaries, tidal pools, beaches, the continental shelf, and the deep ocean. Some mollusks are excellent swimmers, others crawl or burrow in mud and sand. Others remain stationary by attaching themselves to rocks, other shells, or plants; or by boring into hard surfaces, such as wood or rocks. The words mollusc and mollusk are both derived from the French mollusque, which originated from the Latin molluscus, from mollis, soft. Molluscus was itself an adaptation of Aristotle the soft things.

The mollusks are invertebrates and therefore lack a backbone; they are unsegmented and most exhibit bilateral symmetry. Most mollusks can be described as free-living, multicellular animals that possess a true heart, and that have a calcareous exterior skeleton that covers at least the back or upper surface of the body. Adult mollusks can range in size from a few mm (0.1 in.) to over 22 m (>70 ft.) in length as documented for some giant deep-sea squids. Their weight can vary from a few mg (a fraction of an ounce) to over 227 kg (500 lb.) as recorded for the giant south Pacific Tridacna clams. A striking feature of molluscs is the use of the same organ for multiple functions. For example: the heart and nephridia (kidneys) are important parts of the reproductive system as well as the circulatory and excretory systems; in bivalves, the gills both breathe and produce a water current in the mantle cavity which is important for excretion and reproduction.
