Re: rock or gem ??
yep ! that's what that is ! that piece of bone came out of a load of gravel that was around 40-60 ft in the ground, i apprieciate the confirmation on the bone,it's like a rock and sounds like a rock when you tap it,not hollow sounding like any bone would be ,and heavy! thank you broken knee !!

Wow, I looked at the pic and saw some bilateral symetery-could have been anything to me. You find a diagram indicating it is the hoof of a foal. I'm seriously impressed!Broken knee said:The bone you have I believe is a coffin bone from a horse or mule.dscott67 said:

Maybe you could send it to your state university to have it radiocarbon dated. It would be interesting to know how old it is.dscott67 said:had a vet look at it ,it's for certain a coffin bone, and is petrified but from what century is undetermined... and so is the animal that wore it,as it is of the warmblood uncloven hoof perky ear type with a mane and tail !!

Re: rock or gem ??
these are the other ones i picked up,actually two items,i seperated the one into three and if i'm not mistaken it fractured one sided even acording to what i've read over the last couple of days,remember even though i collect some i'm not gem/mineral savvy!! but i'm learning !KEYSHUNTER said:

Re: rock or gem ??
I hope you have the horse coffin bone age-dated. If it is petrified, it's way old as the early horse died out in the Western Hemisphere during the Ice Age and its descendant the modern horse wasn't introduced to this hemisphere until the European invasions in the 1500's. I'm no expert in anything, but come to think of it, isn't any petrified object a silica (or similar) replacement of what was originally there? If so, not organic and maybe it can't be dated? Anyone know the answer to this? Andi

Re: rock or gem ??
unaltered preservation (like insects or plant parts trapped in amber, a hardened form of tree sap)
permineralization=petrification (in which rock-like minerals seep in slowly and replace the original organic tissues with silica, calcite or pyrite, forming a rock-like fossil - can preserve hard and soft parts - most bone and wood fossils are permineralized)
replacement (An organism's hard parts dissolve and are replaced by other minerals, like calcite, silica, pyrite, or iron)
carbonization=coalification (in which only the carbon remains in the specimen - other elements, like hydrogen, oxygen, and nitrogen are removed)
recrystalization (hard parts either revert to more stable minerals or small crystals turn into larger crystals)
authigenic preservation (molds and casts of organisms that have been destroyed or dissolved).

Re: rock or gem ??
To me it looks as the calcium is still present not replaced. and it should sound solid, it's interior construction is sponge like rather than hollow as a leg or arm bone will be. JMO i don't think it is that old maybe a couple hundred years? I could be wrong.

May I ask did you get a load of gravel and found it in it.? Or did you find it in an active gravel pit at that depth?dscott67 said:

Re: rock or gem ??
it came in a load from a gravel pit that i am completely familiar with,this paticular pit is almost at its bottom for production which is 84 ft,now that being said,the load we got was in the 40ft-60ft range depending on what size we were looking for which was the big unwashed rock, which means it came directly out of a drag line type excavator,which means it did'nt ride the conveyor belt, now,that does'nt mean that it could'nt have sifted down from a shallow depth.you could be possibly right on the analysis,i've never found one before so i really would'nt know. i do know that when you take two pieces of flint and knock them together that the sound is distinct,and when i knocked this around it did not sound like a piece of hollow or semi hollow bone,it sounds even like tappin two pieces of glass together,i would just about bet that i would mail it to someone for a sure fire analysis !!! thanks for askin !!Broken knee said:May I ask did you get a load of gravel and found it in it.?
