I hope someone can help me out here. I came across this 28in long x 10in tall (large end), 68 pound piece of either dinosaur bone or petrified wood, several years ago.

It is from the Bryan/College Station, TX area and was supposedly uncovered from a new construction excavation site.

That area yields both, dinosaur bones and petrified wood.
I sure would appreciate your help.

Thanks,
Ken

Too creased to be bone IMO

Bone should have a porous cross-section ...

Thanks RD,

That is part of what has me "stumped" here.
There is quite a bit of porosity on what is either the "joint" or "stump" end:

Here is one more showing the porosity on the large end.

Does it appear to have rings on the thinner end?  If so, it is probably petrified wood.

If you could cut through it cleanly you may get a better idea.... maybe cut a small section away from the thinner end and then hopefully that would remove any erosion and reveal the information that would give you your answer.  Then you would end up with something that would look like the picture RD put up as an example earlier in the post.

The grain pattern looks more woody than bony.  But, it is hard to tell. 

Do you see anything other than the stump that looks like a knot? 

Do you have other pieces of petrified wood or bone from that site to compare?

Please take an end-on photo of the small end.  Are there concentric grains on the small end?

P.S.  I would be reluctant to cut into it, as I think it is quite a conversation piece whole, no matter what the ultimate identity is.  Can you find a paleontologist at a local university or museum?

Well, I am still a dinosaur (over 60) AND

I am on my way back. The chronic pain from the back "injury" or treatment side-effect is slowly becoming something I am getting accustomed to. More opiates would help. Or cocaine. Anyone have Sherlock Holmes' phone number?

I lean to the wood explanation. But it's convincing enough that you can certainly tell your gullible friends, neigbours and relations that is from a dinosaur.  :)
