ID Request - Found near Chattanooga, TN

[wkcarty]

Hello, this is my first post.

 

I recently found this rock and was wondering what these impressions might be. It was found in landscaping near Ooltewah, TN, just north of Chattanooga (the property owner gave me permission to collect it).

 

Are these burrows or traces of something else? I found something similar here, but I didn't see an ID.

 

As an aside, would you crack it open (or saw it), or leave it as is?

I can't give you an exact name (ichnogenus) but these definitely look like lined burrows. I think I would split it open. It will likely expose more of the shapes.

Thanks! I think you pointed me in the right direction.

 

I found this PDF, which shows a similar-looking Ophiomorpha from Alabama, which isn't too far from where I located it.

Do you see the small ball like shapes in the lining of your specimens?
