I am trading an exceptionally rare fish fossil: a complete Lamprey. Its eyes and tail flukes are preserved, and there are also traces of skin as you can see from the pictures. The matrix has a length of 14.7 inches Mesomyzon cf. mengae 135.4 – 126.3 mya | early Cretaceous Huajiying Formation Weichang, Hebei Province I am looking for any of the following: A crab above 5 inches (no Pleistocene/Holocene ones) Uncommon dinosaur material A large amphibian Uncommon ammonite (Anything you feel is worth a trade for this lamprey) Please take note that the matrix is large, heavy and cracked; hence I cannot guarantee that it will arrive without breaking; I can only promise to use a generous amount of bubble wrap and a styrofoam backing to ensure it arrives to you as safely as possible Feel free to ask for more info, pics or videos. Thank you

Squad, I am planning to give a short talk to our North Coast Fossil Club on Saturday 12/16/21 and am trying to find any photos or illustrations show fossil specimens of the unusual plant Welwitschia, which is said to be a living fossil that is known from 113 millions years ago (Lower Cretaceous). There are many articles on the web discussing the modern plant with many good photos of it and its parts, but none seem to show any fossil specimens. Anyone who has or knows where some can be found, please let me know (either here or via PM). Thanks!

I've always loved living fossils, especially the fish. They are relics of an age long lost, offering us a glimpse of an incredible prehistoric world. Some are enigmas that survived countless extinction events since the Devonian. Others are majestic predators that swam alongside the dinosaurs. Let me present my collection of living fossil fishes from the Mesozoic and before. I will begin with one of the most famous of all - the coelacanth Coelacanth Species: Whiteia woodwardi Age: 252.3 - 251.3 mya | early Triassic Formation: Diego Basin; Middle Sakamena Formation Locality: Ambilobe, Madagascar First appearance: Eoachtinistia foreyi was found 360 million years ago in Australia Paddlefish Species: Protopsephurus liui Age: 125.5 - 112.5 mya | early Cretaceous Formation: Yixian Formation Locality: Lingyuan City, Liaoning First appearance: This is the oldest known species Sturgeon Species: Peipiaosteus fengningensis Age: 125.5 - 120 mya | early Cretaceous Formation: Jehol Biota Locality: Chifeng, Nei Mongol First appearance: Multiple species e.g. Yanosteus longidorsalis found since 125 million years ago in China Pipefish Species: Hipposygnathus sp. Age: 28.1 - 13.8 mya | Oliogocene - Miocene Formation: Monterey Formation Locality: Santa Ynez Valley, California, USA First appearance: Solenostomidae species were found 55.8 million years ago in Italy Note: Although most of this collection only includes fishes that existed since the Mesozoic or later, I made an exception for the pipefish as their order, syngnathiform, existed since the late Cretaceous
