Black Nepalese Ammonites! These 140-165 million year old ammonites were alive during the beginning of the jurassic period and collected from the Kali Gandaki River in Nepal at an elevation of 4000 meters above sea level. These pieces are not directly mined for the fossils, but are discovered as locals heat up the shale nodules and split them looking for gold. 🪨💛 #omearthcrystals #ammonite #nepal | Omearthcrystals
