    RSR's Polys Pt. 2

    This is the show from Friday, January 31st, 2020


    Real Science Radio hosts Bob Enyart and Fred Williams discuss polystrate trees, polystrate jellyfish, polystrate tadpoles, and many other kinds of polystrate fossils including vertically buried leaves, a mesosaur buried in varves, a whale in diatoms, a school of whales vertically through four strata, an organism's delicate spines radiating through solid rock strata, nautiloids standing on their points in solid limestone, a school of perch, a dinosaur footprint, and three-dimensional trilobites. To hear Part 1, and to see our list, just click on over to, and see especially the photos of the polystrate footprints and the polystrate leaves, at and (or, for the prints, just below).

    * Dinosaur Footprint Polystrates: as at Denver's Dinosaur Ridge and photographed by an RSR listener...

    The RSR hosts are radio guys and not geologists but Bob is wondering about Colorado's famous dinosaur footprints that, we believe, are part of either the Morrison or the Dakota rock formations. (We haven't checked on that yet; feel free to look that up and send your reply to These deposits stretch from the Denver hogbacks for hundreds of miles to the north. So, how much scientific curiosity do mainstream geologists have regarding polystrate fossils? These particular polystrates establish that these deformed layers, just west of Denver off of Interstate 70, were deposited rapidly enough that they were all still soft at the same time.

    Question: Does mainstream geology have a term for this?

    Answer: No.

    Question: Do mainstream geologists want to know whether their explanations for upright trees can explain these kinds of polystrates?

    Answer: No.

    Question: If these polystrate footprint fossils indicate the rapid deposition of layers that may cover a great extent in the Rocky Mountain region, would mainstream geologists be interested in knowing that, or even, in exploring it?

    Answer, sadly: No.

    (Oh, and to see other footprints, these in Pennsylvanian limestone and also of no scientific interest to most geologists, see the photographs taken by Bob Enyart near McKee, Oklahoma at
