ID this tree seed...

Maybe a heart nut (butternut)? Not sure what they look like without the rind mechanically separated. :{D

but neither resembles it at all..

Might give a clue! :{D

Your sure it's not a hickory, or maybe a ohio buckeye?

show's it broken open, nothing concern-able. I know buckeyes, not even close. Same look inside as outside. I will try and get a better picture.

Google Beech nut, looks similar especially on how it is starting to open up.

It reminds me of course tree bark.

... last year's without the hard shell, which makes it harder.

Check out the leaves and see if you have a tree like that nearby ... unless a squirrel dragged it around for awhile.

Plant it and see what comes up?

:{D

There is no "shell", I will try and take better pic's to post tomorrow...

.
YB, your pics were fine, hold yer horses there!

My post goes "last year's without the hard shell" ...

That crumbly stuff is between the actual seed and the hard shell, BUT during the winter, that shell deteriorates off.

I'll bet if you take a look around at the trees, you'll find your answer!

showing the inside and outside. I see your point Redmink.We will be visiting the tree tomorrow and take more images.

... doesn't look like a seed is in that center (good pics).

It resembles a gall caused by insects, most common are oak galls, but there are others.

Google "tree gall pic" and I think you may agree.

After taking some pic's of the tree then reading up on Gall's, I believe that is what it is... Thanks Everyone for the reply's

Phew! That WAS a tricky one, it was really hard to say. Did you see some of those monster galls when you were looking it up? Wow.

Even though galls are made by insects, I got the sense that no one got too excited about extermination unless it was for fruit trees or ornamental landscaping.

But I'd heard a rumbling about an infestation of ash borers, so keep an eye out.

Would have the 'Gall' to start a thread like this.

Don't quit your day job >;)

I ain't got no day job, I be retired and loving it. Ho Ho Ho.

you acted retired even when you DID have a day job.... slacker >:P
