  • Hello fossil/ science lovers , I belong to the oldest fossil club in the USA . I have posted many of our beginners classes , field trips and paleontologist lectures.

    If you type in "Cincinnati Fossils" or "Dry Dredgers" in the search engine you will see over 50 videos to choose from . I thought some of you might enjoy these so I'm passing this on .New videos posted every year !
