Date my sherds from ichnofossils?

[kerrimarie805]

 

I thought I was joining my husband in his kingdom of Pareidolia when I thought there were mold or trace fossils, which I now know as ichnofossils, on some of my sherds from time to time. I have no idea how long it takes for such fossils to form, and I often don't have a guess as to how old a sherd might be or how long it could have been in the ground or water, but I am changing my mind. I see fossils on my sherds and I'm not crazy  (well....)! I hope these examples are photographed well enough for you to see them, too. I'm very curious if this is common and if I can date the sherds according to the fossils.

Sorry, but I am not seeing any ichnofossils there.  

If you are talking about the lighter colored lines on the right hand specimen, those may be modern root etchings.

This looks like broken pieces of crockery. It is glazed so not very old.

It is and I'm sure they can't be, bad examples. I'll find better ones to show you what I'm talking about.

I imagine it could be determined to some degree how long it has been in contact with living roots (a trace indeed) but the age would put the endeavor in the realm of archaeology rather than paleontology.
