Any help in identifying this is greatly appreciated. Not sure of the origin location, but it was given to my sister in Massachusetts by a neighbor that was moving.  About 12 inches tall and 8 inches in widest part of cross section (not exact...estimating from memory).

Welcome to TFF!

It looks like it could be some type of petrified wood.

But the pictures are out of focus and at oblique angles, this makes it hard to be sure what it is.

If You can reshoot the pictures in direct daylight and straight on it would help.

 

Regards,

Tony

Judging by what I can make out on these images, I'm not seeing the radiating lines and growth rings I would associate with petrified wood, and so wonder if this is a concretion? :headscratch:I'm hoping it is pet. wood, though. :)

I'm with concretion. I think the wood like indications may be a feature similar to slickensides. I forget the exact term for this version.

looks like a cast of a tree trunk, something like Calamites sp.

Concretion/ possibly a tubular, water created vacancy in rock that became infilled. If it's from Massachusetts, I don't think there were creatures large enough in the state's fossil record to have produced a burrow this size.

I can't see indications of wood.

I'd be interested in seeing an example of one of those.

after blowing it up and enhancing it, I do not see any plant features. Maybe concretion.

I have some if you still wish to see pics. 

 

I also believe it is a concretion. However, the calamities I have came out of a concretion that looked like that exact material.

I have many Carboniferous plant concretions.

The vast majority of these are pith casts. A complete cast showing the external mold would definitely be of interest.
