Fossils are the remaining evidence of life that flourished millions of years ago. They are generally found in layers of sedimentary rocks originally deposited by the erosive action of water. Using modern technology, scientists have been able to determine the age of rock and mineral deposits as well as that of the formations in which fossils are found. Using that information, they devised what we commonly refer to as the Geologic Time Scale. To learn more about sedimentary rock formations, visit our Rock Cycle page. For more about geologic periods, check out our Geologic Time Chart.

Geologic Time Chart - Our 11" x 17" chart is a typical example of the Geologic Time Chart that shows the Eras, Periods and Epochs of Time. Time is indicated in Millions of Years Ago (MYA).

The estimation of Time is not necessarily exact. For example, the Paleozoic Era did not begin precisely 544 MYA. The actual event when the Precambrian Eon became the Paleozoic Era may have been either thousands of years earlier or later. As the time chart comes closer to the present, the estimation of the passage of Time becomes more exact because there is more geologic evidence like fossils. The intervals and units of Time may change as geologists find more geologic evidence that delineate the respective units.

Triceratops Frill - These pieces of petrified frill are approximately 1" x 1" in size. Frill was the bony plate that curved upward behind the skull. The frill was highly vascular. It is believed that the frill was responsible for helping regulate the body temperature of the triceratops as well as providing protection.

Triceratops Teeth - These teeth are from the Hell Creek Formation in Butte County, South Dakota.
Small - $25.00

Dinosaur Coprolites - These are pieces of petrified dinosaur dung. Dinosaur coprolites are valuable trace fossils for figuring out the paleo diets (or feeding behavior) of dinosaurs. Coprolites also provide information about habitats and the presence of dinosaurs in areas otherwise lacking dinosaur body fossils or other trace fossils (such as tracks).

These larger round coprolites are from the Morrison Formation in Utah and are agatized. Agatized coprolite often displays remnants of what dinosaurs consumed in colorful patterns within the coprolite matrix. These coprolites can be cut and polished. Large are about 2.5", and XLarge are about 3.5".
Large - $20.00

XLarge - $28.00
Dinosaur Bone - These are pieces of genuine fossilized dinosaur bone fragments. Dinosaurs lived only during the Mesozoic Era, often called the Age of Dinosaurs. The Mesozoic Era (252 to 65 MYA) is divided into three time periods: The Triassic (252-200 MYA), the Jurassic (201-144 MYA), and the Cretaceous (145-66 MYA).

These fragment are from Utah and mostly brown in color. There are some pieces that have other colors like red, green and black. Bone structure is visible in all pieces. Order by size:

Mosasaur Teeth - The Mosasaurs were Late Cretaceous period meat-eating marine reptiles that had long heads, strong and flexible necks and hydrofoil-like limbs. Mosasaurs had long and powerful bodies whose tails and limbs were adapted for swimming.

They probably swam by moving their long body in a snake-like way, also using their finned tail to propel them forwards. They steered with small, webbed feet. The mosasaur was a powerful swimmer who spent its entire life in the sea. They were the largest lizards that ever evolved and attained lengths of almost 60 feet with a skull 6 foot long.

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!
$3.50 ea.

Large Lace Fern - Coal Fern - Alethopteris sp. (Pennsylvanian) - These Coal fern leaf impressions on shale are from the Buck Mountain #5 Coal seam located along the boundary of the Upper Sharp Member of the Pottsville and Allegheny Series.

These nice specimens are a little over 3.0" in size. Get yours now!

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.
$7.00 ea

Gastropods (small) - These small gastropods, Tyolostoma 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.
$2.00 ea

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.
$10.00 ea.

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).
$10.00 ea.

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.
$5.00 ea.

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.
$4.00 ea.

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.

medium in rock matrix about 1.25"

Medium (2 pk) - $5.00

Large (1 each) - $10.00
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. Order by size:

small average about 1.0"
medium average about 1.5"
large average about 3.0"

bag of 10 pieces average size is about 1" x 1"
Small - $3.00

Med - $4.00

Large - $10.00

10-Pack - $18.00
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"
Small $4.00

Medium - $7.00
