When trilobites first appear in the fossil record they are already highly diverse and geographically dispersed. Because trilobites had wide diversity and an easily fossilized exoskeleton an extensive fossil record was left behind, with some 17,000 known species spanning Paleozoic time.
Orthoceras ("straight horn") is a genus of extinct cephalopod. Orthoceras are dated to the lower Ordovician to Triassic ages (500 to 190 million years ago). They are ancestors to the modern day squid. The Orthoceras ranged in size from a few inches in length to over six feet.
Ammonites are perhaps the most widely known fossils, bearing typically banded spiral formation shell. They lived in the sea between 415 - 65 millions years ago. They suddenly became extinct, around the same time as the demise of the dinosaurs, 65 million years ago.
Petrified Wood is a fossil. When all the organic materials of the original wood are replaced by minerals over time, while it retains its original structure, it becomes petrified. All the original features of the wood are still evident once petrified. Evidence of the tree rings, bark, and wood tissues can be seen.
The Carcharadon Megalodon is an extinct species of shark, ove 30 million years old. It dwarfed today's great white shark - sometimes reaching lengths of as much as 80 feet. The extinct Otodus Obliquus Shark was once a fierce predator of the ocean, an ancestor to today's great white shark.
Amber is fossilized tree resin. Amber helps remove energy blockages, and strengthens the body. Excellent for enhancing altered states of consciousness. Corresponds to Crown and Solar Plexus Chakras.
No rock collection is complete without a Coprolite! Coprolite is fossilized poop! These Coprolites come from Madagscar, and are from the Eocene period (approx. 50 million years old.) They come from prehistoric turtles.
Fish Fossils from the Green River formation, Wyoming USA. Early Eocene, 40-60 million years old. Fossils are in sandstone, with nice features.
We have an assortment of other fossils available, including gastropods, brachiopods, bivalves, crinoid stems, and fern fossils.
