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.

Basic Fossil Type Kit - Not all fossils are petrified. Surprised? Learn about the different types of fossils in this EZ 2 Kit. 6 specimens with instructions.



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 1.0 - 2.0 inches 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 - $15.00

Med - $23.00

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).

The smaller tubular coprolites are from the Bull Canyon Formation in northeast New Mexico and are of Triassic age. While it is not possible to identify the type of dinosaur these coprolites came from, they could possibly be from the meat-eating Coelophysis, a reptile that was common in the area. Order small (about 1.0") or medium (about 1.5") for the New Mexico coprolites.

The 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. Order large (about 2.5") or extra large (about 3.0") for the Utah coprolites.

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 345 - 280 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!

$ 1.50 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!

$12.00 ea.


Horn Coral (Tabulophyllum sp.) - Each of these solitary, cylindrical specimens are unique. Their exteriors are covered with longitudinal ridges and concentric wrinkles, concentric wrinkles and growth lines. Horn Coral are widespread in North America and were very common in the Mississippian period. Our specimens are over 325 million years old and are from Millard County, Utah. Coral specimens can be found in the fossil record from the Cambrian period on, hence coral fossil remains are a common component of limestone.

$ 1.00 ea.


Bulk Horn Coral (Tabulophyllum sp.) - A recent purchase makes these newly acquired horn coral fossil specimens available in bulk. These pieces are a little smaller and not quite as nice as the individual specimens above but are great for basic classroom work. At this price, each student can have a piece of their own! There are approximately 50 pieces in each of these one pound bags making the cost of each piece approximately $0.16. Sizes vary from 3/4" to 2.0". Horn Coral are widespread in North America and were very common in the Mississippian period.

$ 8.00 per pound.


Gastropods (large) - Cassiope sp. - Approximately 2" to 3" in length. This is an excellent example of a Cretaceous Period gastropod from Iron County, Utah. These detailed "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 EZ2 Fossil Type Kit - item #312.

$ 3.50 ea


Gastropods (small) - These small gastropods are approximately 1/2 inch long. Gastropods (uni-valves), the largest class of mollusks, are covered with one hard armor-like coiled shell which protects the soft bodies. Gastropods, meaning belly foot, crawl mainly be means of ripples that pass across it belly. A large muscular foot spreads beneath the body. Their tongue, a rubbery ribbon covered with thousands of tiny teeth, works like a file in tearing apart its food.

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 inch
medium average about 1.5 inch
large average about 3 inches

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 average about 1 inch
large average about 3 inches
small $3.50

large - $6.00


Gogia spiralis - (Eocrinoid) - These are excellent examples of Cambrian Period eocrinoids from Wheeler Formation of Millard County, Utah. As so known as the dawn crinoid, Gogia spiralis is a Cambrian cystoid that is among the earliest and most primitive groups of echinoderms. Gogia differed from true crinoids in that they had pores along the margins separating the plates, and the type of feeding arms they displayed. They derive their name from the spiraled arms and they added arms in such a way as to have an odd-numbered total.

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. CLICK HERE for the 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. CLICK HERE for the price list by types.
