Auspex Posted June 12, 2014 Share Posted June 12, 2014 This is a large plate (23" X 23") from the Hell Creek Formation, showing nice ripple marks, some viney Equisetum-like vegetation, and several 4 1/2" wide bird tracks: "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!

Stocksdale Posted June 13, 2014 Share Posted June 13, 2014 I find small parts of ripples occasionally in the Francis Creek Shale/Sandstone in which the Mazon Creek concretions are embedded. I think they are neat because they show the coal forest being inundated by the oceans. I'll see if I can photograph one. Somewhere, something incredible is waiting to be known.–Carl Sagan Link to comment Share on other sites More sharing options...
JohnBrian Posted June 14, 2014 Share Posted June 14, 2014 I did inventory in a wrecking yard many years. I found this & several other interesting rocks in the bed of a wrecked pickup. The truck was used in the oil fields in the Paso Robles, CA, area. Sorry I can't get more specific!. The rock itself is very heavy for its size. It is ferrous as a rare earth magnet (VERY powerful) will stick to it just enough so that it doesn't slide off but the magnet will not pick the rock up. ---------------------------------------------------------------------------- John Link to comment Share on other sites More sharing options...

Stocksdale Posted June 14, 2014 Share Posted June 14, 2014 I was at a Mazon Creek (Illinois) coal mine pile today and picked up some ripple marks in the Francis Creek shale.
