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...

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.

Petrified Wood is a fossil in which the organic remains have been replaced by minerals in the slow process of being replaced with stone.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...

Rare juvenile fossilized porpoise vertebra. This particular example demonstrates a lumbar vertebra of a porpoise with epiphysis (growth plate) on both sides indicating it was a juvenile. It is rare to see both epiphysis as they easily slip off the vertebra. The opening in the spinous process is to allow for the spinal cord. The two transverse process have deteriorated. Overall measurement: 3.5 inches long by 2.25 inches wide by 1 inch thick...

A set of six fossilized dusky shark teeth (Carcharinus obscurus). Related to today’s Red Sea shark. Excellent large size examples that detail dentine (root), crown, serrations and nutrient groove. Overall measurement of each tooth is 1 inch by 0.75 inch. Age: 5 million to 25 million years old. Location: Westmoreland County, Virginia. Ryker box included.

A set of five fossilized snaggletooth shark teeth (Hemipristis serra). Excellent large size examples that detail dentine (root), crown, serrations and nutrient groove. Overall measurement of each tooth is 1 inch by 0.75 inch. Age: 5 million to 25 million years old. Location: Westmoreland County, Virginia. Ryker box included.

A set of five fossilized tiger shark teeth (Galeocerdo cuvier). Excellent large size examples that detail dentine (root), crown, serrations and nutrient groove. Overall measurement of each tooth is 0.875 inch by 0.875 inch. Age: 5 million to 25 million years old. Location: Westmoreland County, Virginia. Ryker box included.

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.
