Lace Fern - Check out these really nice Pennsylvanian Period ferns from the fossil-bearing Llewellyn Formation located in the the Southern Anthracite Coal Fields of eastern Pennsylvania.
The formation is composed of a fine-grained detrital sedimentary rock (shale) formed by the compaction of clay and silt. Seed ferns were prevalent during the Carboniferous Period 359 - 299 million years ago. Some species reached heights of 30 to 40 feet.
These ferns accumulated in the fresh-water swamps, where they were buried along with the clay and silt to eventually be transformed into coal. The plant tissue was slowly replaced by pyrite which was eventually covered by a white coating of the mineral pyrophyllite. A great buy! |

Gastropods (large) - Cassiope sp. - Approximately 2.0" to 2.5" in length. This is an excellent example of a
Cretaceous Period gastropod from Iron County, Utah. These detailed authentic fossil "casts" were formed when the original organic material inside the shell was replaced by calcite over millions of years. For additional information about different "types" of fossils, see our Fossil Type Kit - Item 312-000, listed above. |

Gastropods (small) - These small gastropods, Tylostoma sp., are approximately 0.75" long. Gastropods (uni-valves), the largest class of mollusks, are covered with one hard armor-like coiled shell which protects the soft bodies. Gastropods, have a belly foot, which is a large muscular foot that spreads beneath the body that allows them to crawl by means of ripples that pass across the belly foot. |

Brachiopod (large) - Dictyoclostus bassi C - lived during the Permian (~275 mya). Braciopods are referred to as Lamp Shells. The outer shell is made of two unequal valves. This specimen was found in the Kiabab formation in Washington County, Utah.
Size range from about 1.5" to 2.0" across. |

Pelecypod Oyster - Ostrea sp - Oysters are bivalve mollusks, most of which live in marine habitats or brachish water. The shell consists of two unusually highly calcified valves surrounding a soft body. This oyster is from the Cretaceous period, found in Strait Cliffs, Utah.
Size range from about 2.0" to 3.5" long. The photo shows two specimens, one showing the slightly concave inner shell and the other showing the rough outer shell (artifical gloss finish to better show characteristics of the shell). |

Pelecypod Oyster - Gryphaea arcuate - This oyster (bivalve mollusk) is commonly referred to as the "Devil's toenail" because it has a larger gnarly-shaped shell ("toenail") and a smaller flattened shell. The soft bodied oyster lived in the gap between the two shells. This oyster is from the Cretaceous period, found in Utah.
Size range from about 1.25" to 2.25" long. |

Pelecypod Clam - Clams are bivalve (two-shelled) mollusks and are related to oysters, quids, slugs and snails, all from the Class Pelecypoda. They lived primarily on the shorelines of oceans (marine) and lakes (freshwater).
Specimens are about 1.25" long. |

Turritella or Elimia Agate - These gastropod mollusks are medium sized snails that are white to tan in color in contrast with the brownish quartz agate rock matrix they are found. When this fossiliferous rock was first discovered it was believed to contain marine snails from the Turritella genus. However, it was later determined that these actually were freshwater snails, Elimia tenera. These specimens are from the Green River Formation in Wyoming.

Petrified Wood - These are pieces of genuine petrified wood. Petrified wood is actually considered to be a fossil. It forms when plant material is buried by sediment and protected from decay by oxygen and organisms. Then, groundwater rich in dissolved solids flows through the sediment replacing the original plant material with silica, calcite, pyrite or another inorganic material such as opal. The result is a fossil of the original woody material that often exhibits preserved details of the bark, wood and cellular structures.

Petrified Wood with Quartz Crystals - These are very interesting and unique specimens. The organic matter in the original tree was completely replaced by minerals. This type of fossilization is known as permineralization. The term, "to petrify", literally means, "turn to stone." Petrified wood, then, is wood that has turned to stone. In these specimens the core actually crystalized forming hundreds of tiny quartz crystals.Order by size:
Small is about 1.25"
Medium is about 2.25" |

Triops Kits Before the dinosaurs, there were Triops. Fossil Triops more than 200 million years old have been discovered. By comparison, dinosaurs date back only about 60 million years...just 'youngsters" in terms of geologic time.
Triops are distant relatives of trilobites. Triops means " three-eyes" while the name trilobite means "three lobed" or "three segments. Check out the Triops page for a listing of the different triops kits. |

Trilobites are a type of extinct marine arthropod probably most closely related to modern Horseshoe crabs. They first appeared in the fossil record in the Early Cambrian some 521 MYA and went extinct some 252 or more MYA during the Permian period. We offer three types of trilotibes. They are the Diacalymene ouzregui sp, the Elrathia kingi and the Agnostid. Go to the Trilobites page for price list and types. |
