Description: This set includes info sheets on trace concave and convex trace fossils, ferrous amalgamation (the Mazon Creek process), and on the process of oxidation in redbeds that left traces of root systems and even of soft tissue plants. Please note that all of our fossils are from the continental United States, from NE New Mexico, US, that was once part of Pangea. For background information of our fossils and fossil quarry please visit the following blogs: Exceptional early Permian footprints, and, Dimetrodon's ichnology and other Permian footprints. (Copy, open new tab and paste, click on address if applicable.) Please note that evidence exists that the El Pueblo swamp facies is of Pennsylvanian age (305 MYA). A paper When the Geologic Time Scale Does Not Match the Evidence: is available to read on Academia.edu. This geologic time difference is negligible although we now know the site is an early evolution site (small dimetrodons and very large amphibians). Because of the many internet references an early Permian age designation will continue. The general biological evolution interval is after lobe finned fishes evolved feet and before large dinosaurs appeared. Contact for any questions you may have. Please note that our policy is return within fourteen days for full refund.
