Thanks guys. These are rather large bones...about a foot in length and four or five inched in diameter. Of course, the locals have been chewing on them a bit, but there appears to be quite a bit of material to work with.
I think the current farmer's father must have dumped the dead off around here or something...
Im going to collect what I can and see where that leads.
Doug, still looking for some rock too. All of it is freeze fractured so far but Im still looking....but I just might have a connection to some great flint from Europe....
