Fossil Ammonite Ammonite is the fossilized shell of ancient sea amminoids and nautiloids, ancestors of today's pearly nautilus. A fossil formed when the animal's shell absorbed minerals from silt. The compression of centuries of successive sediment layers turned the skeleton to rock. Ammonite, this is a fossil stone, often called snake or serpent stone. Ammonites are an extinct group of marine animals of the subclass Ammonoidea in the class Cephalopoda, phylum Mollusca. They are excellent index fossils, and it is often possible to link the rock layer in which they are found to specific geological time periods. Their fossil shells usually take the form of planispirals, although there were some helically-spiraled and non-spiraled forms (known as "heteromorphs"). Their spiral shape begot their name, as their fossilized shells somewhat resemble tightly-coiled rams' horns. Originating from within the bactritoid nautiloids, the ammonoid cephalopods first appeared in the Late Silurian to Early Devonian (circa 400 million years ago) and became extinct at the close of the Cretaceous (65 million years ago) along with the dinosaurs. Fossils have been revered in the magical practices of many lands, and legends explain their origins. Fossil stones have been found in mounds of many burial sites, and thought to have eased the right of passage. They are a symbol of long life, since they contain the life force, which is released in healing in a gentle but potent way. Ammonites especially, were used traditionally to relieve pain and to ease birth. Fossils will help to bring tradition and character to a newly built house or apartment, or one in a soulless area. To recharge a fossils energy, place in a ancient place, best of all within the sound of the sea or running water.
Fossil Trilobites What are Trilobites? Trilobites are perhaps the most famous and easily recognized fossil invertebrate group. The name comes from the length wise division of the body into three lobes—two side (pleural) lobes separated by one central (axial) lobe. All trilobites had antennae and legs with two branches, one used for locomotion and the other for respiration. Some had compound eyes, like a modern fly. Trilobites were strictly marine animals, but they were very diverse, living in both shallow and deep waters. Their First known fossil occurrence is in Cambrian era. Their Last known fossil occurrence is in Permian era. Trilobites flourished in the oceans of the Cambrian and Ordovician periods, beginning around 540 million years ago, with a diminishing number of families persisting until the Permian. The number of families peaked in the Late Cambrian when an extinction event removed many. The morphological diversity actually peaked in the Ordovician. Many more families were removed at the end of the Ordovician 440 million years ago during a great ice age where ice sheets advanced to the equator. The diminished number of trilobite families that survived to the Silurian radiated into new and exotic forms, and still more exotic spiny and pustulose forms in the Devonian. The Elrathia kingi trilobite fossils are found in the Wheeler Shale Formation in Western Utah, USA(Age: Cambrian - ca 505 million years ago).
Fossil Shark Tooth Prehistoric sharks teeth may be black, brown, or gray, depending on the minerals in the soil in which they have been buried. They range in size from one eighth inch to three inches. For millions of years, sharks have lived and died in the Gulf of Mexico. Dead sharks sink to the ocean floor where they are covered by layers of sand and silt. Over time, the cartilage of their bodies disintegrates. Water and storm action eventually sweeps the sand away, exposing the teeth. Some are washed up on shore with the changing tides and waves.
