This is the preview post #5 for the 2025 ESCONI Gem, Mineral, and Fossil Show Live Auction.  The ESCONI Gem, Mineral, and Fossil Show for 2025 will be held on March 15th and 16th at the DuPage Fairgrounds in Wheaton, IL, which is the same location as last year.   All details can be found here.


Mazonova helmichnus is on the breakfast menu this morning.  This Mazon Creek fossil species is thought to be eggs from an amphibian or maybe lungfish.  We did a post about M. helmichnus in Mazon Monday #118.  

This specimen will be part of the second auction on Saturday, March 15th.
