Chert, Chalcedony, Fossil Coral/Sponge, Eye Agate, Stalactit

Have been trying to figure out just what these are since 2016. The title lists all of the ID’s I have received, either in person or online.



Each one pictured is a little different, but most have the same basic pattern. Some have quartz replacement in the centers. Some have Chain/Favosite/Honeycomb coral type features on the outside of centers or on an exposed edge. Most have some type of oolictic presence.



Am showing some with just the pitted surface.



Most are between 3-8” long. About a 7-7.5 hardness.



Hope to be able to slab some in the near future. Have about 250 lbs. of this material, maybe more.



Found at location on my Avatar. Central Wisconsin, USA. Area full of glacial deposits. Am becoming more unsure of ID now than when I started researching in 2016.



Thank you.



1  Favosite/Honey Comb?







2.  Same as above?





3.  No clue.  Thought it was a coral, due to some chain like features around the pits.  









4.  Fossil mud?  One appears to have trace critter or critter tracks in it.  Two rocks.  The first appears to have some Opal like features. 







4a.  This one seems to have some type of tracks.






 

5.  Appears to be a trace fossil of a plant?  Or water was trapped?  Do not think it is chert.










6.  Grab bag of some others.  All tubular patterns.  Variety of colors.  Most have oolictic features in the host rock portions.  



The black areas in this one are magnetic and may be meteor dust?





























 Think that is enough for now.  
If someone here said these were chert, please do not be offended on my questioning your ID.  I just do not believe they are chert.  
Need to figure out what they are.  Think I have a good handle on some.  


Thank you to those who made it this far.  Any ID help/confirmation would be appreciated.  

I lost some of my notes due to a computer issues and know some were positively ID'd in the past.
