I posted these in the 'gallery' area, but haven't got many views so I thought I'd try them in here. I don't know if pics tell the full story, but I'm hoping maybe someone has found them before and knows what they are. To my 'rookie' eye, they appear to be teeth because of the unique striations. I thought they may be petrified wood at first, but I've found a lot of that now and no longer think it is so I'm now leaning towards teeth.
I'm sorry, I haven't figured out yet how to post the pics in here since I posted the gallery from a different computer. Please check out the album through this link; http://www.thefossilforum.com/index.php?/gallery/album/1644-n-sulphur-river-trip-3-4-teeth/
All input is greatly appreciated,
