Fossilized megalodon shark tooth in natural matrix. These sharks are extinct now but the modern Great White sharks are their relatives. This tooth measures 3 inches long by 2 inches wide equating to a 30 foot eating machine. Age: 5 million to 25 million years old. Location: King George County, Virginia. Overall measurement 6 inches wide by 6 inches long by 6 inches tall.

Beautiful and rare crystal to milky quartz formation formed during volcanic age on the Mid-Atlantic U.S. coast. Located in one of the two known caves in the Northern Neck of Virginia. Overall measurement is 11 inches by 12 inches. Weight is 18 pounds. Note: requires special shipping by U.S.P.S. Please inquire by email with city/state and zip code destination for postal estimate.

Two fossilized ammonites (one large, one small) in matrix. These are the ancestors of today's octipi and squid. Found in the Mid-Atlantic coastal region of the U.S. Age: 200 million to 250 million years old. Overall measurements: 6.5 inches wide by 7 inches tall by 2 inches thick.

Fossilized trilobite (Phacops rana) in natural matrix. It is fairly large in size (up to 6 inches long). It protected itself by rolling up into a ball much like a pill bug in order to protect itself from predators. Its exoskeleton was on the outside. The most striking feature is its large eyes located on turret-like structures able to rotate 360’. Age: 400 million years old (Devonian Era). Location: King George County, Virginia...

Excellent example of a fossilized Mastodon tooth (Mammut americanum) found in the Mid-Atlantic region of the U.S. Solid black in color. Overall measurement is 2 inches wide 3 inches long and 2 inches tall. Shows great detail. Age: 10, 000 years to 3.7 million years old. It was once believed the Mastodon was the ancestor to today’s elephant but DNA studies have proven they are not related.

An educational package consisting of four fossilized megalodon (Carcharocles megalodon) teeth. This set is perfectly suited for "Show & Tell" allowing students to handle and visualize the stages of fossilization. These specimens detail crown, dentine and enamel wear. Size ranges from 2.5 inches by 2.5 inches to 1.25 inches by 1.25 inches. Age: 5 to 28 million years old. Location is Clavert Cliffs, MD>

A prime example of fossilized barnacles traced to the Paleozoic Era, Devonian Period (between 360 million to 410 million years ago). Barnacles play an important role in estimating paleo-water depths. A barnacle is a type of arthropod belonging to the infraclass Cirripedia in the subphylum Crustacea, and is hence related to crabs and lobsters. This specimen is perhaps of the Regerella species. Overall size measure 5 inches by 5 inches. Location: King George, VA.

Large example of a fossilized whale rib bone; most likely a baleen whale. This particular specimen measures over 12 inches long by 3 inches thick showing a unique lateral split exposing the internal bone marrow. Great view of fossilization process. Age: 5 to 28 million years old. Location: Flag Pond, MD.

A perfect example of Chesapecten jeffersonius, a scallop that lived during the Pliocene epoch between four and five million years ago on Virginia’s coastal plain. In 1687, Martin Lister published a drawing of Chesapecten jeffersonius making it the first North American fossil to be illustrated in scientific literature. In 1993 the state of Virginia made it the official state fossil. Size measures 6.5 inches by 6 inches. Location: King George, VA.

Petrified Wood is a fossil in which the organic remains have been replaced by minerals in the slow process of being replaced with stone. The petrifaction process generally results in a quartz chalcedony mineralization. Special rare conditions must be met in order for the fallen stem to be transformed into fossil wood or petrified wood...

Fossilized ammonites are an extinct group of marine invertebrate animals in the class Cephalopoda of the subclass Ammonoidea of the order Anarcestida. Genus and species are unknown. These mollusks are more closely related to the squid and octopus. Overall measurement is 1.5 inches by 1.5 inches. Age: 360 million to 420 million years old (Devonian Period). Location: Richmond County, Virginia. Ryker box included. Note suture marks (showing growth over a period of time) on weathered area of fossil.
