The Amateur Paleontologist Posted March 9, 2020 Share Posted March 9, 2020 Wow! Those are some really cool fossils 1 Opalised fossils are the best: a wonderful mix between paleontology and mineralogy! Q. Where do dinosaurs study? A. At Khaan Academy!...

fossilnut Posted March 9, 2020 Share Posted March 9, 2020 For a couple of years I have been looking for articles/ info on pyritization of fossils with the goal of putting together a talk for a fossil club. I don't have the chemical and biological background so am trying to absorb and gain a basic understanding of how pyrite thru diagensis "preserves" the soft tissue of various animals and plants. The Beecher Trilobite beds are amazing. I did get to collect briefly in Alden NY and have some brachiopods from the Silica Formation in Ohio(understand these are not soft tissue preservation). If anyone has info on the process or outstanding examples, I would appreciate letting me know. Thanks Link to comment Share on other sites More sharing options...

Tidgy's Dad Posted March 9, 2020 Share Posted March 9, 2020 Amazing appendages on those trilobites. Despite covering the trilobites a little, I rather think the bryozoa add to the piece as well. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
