Trace fossil?

[MSirmon]

I found this in our property southeast Oklahoma. The area is Pennsylvanian in age. My first thought was that it may be weathered barite (Rose Rock) which is the state rock. However, they are Permian in age and not found in this area to my knowledge. Now I’m thinking either weathered chrinoid  (calyx?) maybe a cluster of burrows, or just a really cool looking rock. Any help would be appreciated. The item is 4” x 5.5” in size.

First picture looks like classic trace fossil (a.k.a. ichnofossil) burrows to me.

Maybe something like Thalassinoides sp.

Ah! But which side is up ?

Please post a top-down view, preferably with indirect offset lighting so we can see the relief of the burrows.

I'm thinking it's a convex hyporelief.

I will send them when I get back home. Currently running around Arkansas fossil hunting and checking out architectural salvages.

I think this is what you’re asking for.

Thanks for the additional photos...

Somewhat less ichno ?

Hmm.  Yeah, less fossily.

Maybe a geologic feature like Dale suggests.

Leaverite?
