(Green River Formation) 🐟\n\nAuthentic Eocene-age fossil fish (Knightia sp.) preserved in fine limestone matrix from the Green River Formation. This specimen shows a clear articulated backbone, rib structure, and forked tail with visible fin rays — classic features of this extinct freshwater fish that lived approximately 50 million years ago.\n\nThe fossil is naturally preserved and professionally prepared, leaving the bone detail intact without over-enhancement. A great display fossil for collectors, classrooms, or anyone interested in prehistoric life.\n\nDetails:\n• Genus: Knightia sp.\n• Age: Eocene (~50 million years old)\n• Formation: Green River Formation\n• Natural limestone matrix\n• Single fish specimen\n• One of a kind – exact piece shown","brand":"Earth's Sparkles","offers":[{"title":"Default Title","offer_id":48007868285149,"sku":null,"price":60.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0834\/5115\/0557\/files\/0fa19286-il_fullxfull.7700123899_a94a.jpg?v=1780935580"},{"product_id":"polished-ammonite-fossil-with-uv-reactive-calcite-and-pyrite","title":"Polished Ammonite fossil with uv reactive calcite and pyrite","description":"Cut and polished by myself, this beautiful pair has it all!

Ammonites are an extinct group of marine mollusks that lived from the Devonian period until the end of the Cretaceous period. \nThey belong to the class Cephalopoda, which also includes modern-day octopuses and squids. \nThe fossils are characterized by their coiled, chambered shells, which were used for buoyancy. \nThese specimens may be a species of Mortoniceras.","brand":"Earth's Sparkles","offers":[{"title":"Default Title","offer_id":48007869563101,"sku":null,"price":50.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0834\/5115\/0557\/files\/b2bfa54c-il_fullxfull.7667767877_rap1.jpg?v=1780935596"},{"product_id":"orthoceras-fossil-sphere-polished-limestone-display-specimen","title":"Orthoceras Fossil Sphere, Polished Limestone Display Specimen","description":"An Orthoceras sphere is a polished, spherical object crafted from rock containing Orthoceras fossils, which are the preserved remains of an extinct type of cephalopod. These fossils are typically found in dark limestone matrix and are characterized by their distinctive straight, conical shells, which is where the name \"Orthoceras\" (meaning \"straight horn\") comes from. \nInformation about Orthoceras Spheres:\nOrigin and Age: Orthoceras fossils are primarily found in Morocco and date back to the Ordovician period, over 400 million years ago, making them ancestors to modern-day squid and nautiloids.\nComposition: The spheres are made from carboniferous limestone matrix containing the fossilized remains of Orthoceras, often with the shells replaced by calcite.\nCharacteristics: They typically exhibit a striking contrast between the dark matrix and the lighter-colored fossilized shells. Due to the natural material, perfect spherical shapes may not always be achieved.\nUses: Orthoceras spheres are commonly used as decorative items, display specimens.","brand":"Earth's Sparkles","offers":[{"title":"Default Title","offer_id":48007869497565,"sku":null,"price":28.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0834\/5115\/0557\/files\/c965b04a-il_fullxfull.7224866599_p9ye.jpg?v=1780935592"},{"product_id":"orthoceras-4-dish","title":"Orthoceras 4” dish.","description":"Orthoceras: were ancient, extinct cephalopods, a type of marine mollusk related to modern-day squids and octopuses, characterized by their straight, conical shells. \nThe fossils are embedded in a matrix, likely limestone, which is a common material for carving and sculpting due to its durability and the abundance of these fossils. \nSuch pieces are often used for decorative purposes, including carvings, sculptures, and even furniture.
