As an example:most mammal skin is gone in about 138 days in a temperate(moderately arid)climate and subaerial exposure.

 

The "fossil skin" is actually impression of the real skin in mud that become rock.Real skin is impossible to become fossil.

The irregular reticulate structure of the specimen in question reminds me of Boxwork .

I assume boxwork is all geological though. I haven’t done any more work on the piece. If it isn’t a fossil I’m not sure I want to waste my time on it. It is an interesting piece.

It sure looks like it isn’t geologic, but then I can’t figure out what it could possibly have been if it was biological.

This one looks like a crushed bivalve shell.

 

 

The internal marginal crenulation is visible.

I think you got plant matter. A bit of bark, an inside layer plus a stem (them stems sure do look like lil bones). I've been pouring over plant fossils for weeks and the hardness of the rock + 'skin'print + the structure that looks like bone just screams plant to me. If I wasn't so tired I'd take a few pics to show ya some specimens I've found. I will add them in the morning.

This is actually convex. That pic looks concave, but it isn’t.

It may be part of s bivalve though. There is this regular pattern all the way around the oval shape. It isn’t the best pic, but you can see these tiny white dashed line going from top to bottom. Those are maybe 1mm at most. It is the most regular and perfect pattern. 

The piece is mineralized. It is pretty hard to scrape.

I can't see the what you are seeing, Kim. 

Can you post a picture of the specimen from a  lateral view?

[KimTexan]

Sorry, the dashed line is so fine it is difficult to get a clear shot. I don’t think the white dots are even 1mm. I changed the contrast.  The line of white dots stands out more. I circled them.
