Bone with what looks like teeth marks?

[Petrified]

I found this gold panning in glacial deposit in northern Pennsylvania.  Glacial drift material comes down from Canada so would be impossible to put time frame on unless carbon dating.  My guess would be around Ice age period.  Now the question is if for one this is bone in which I think is but need facts.  Question two is does this look like teeth marks on side of material?  Im hoping because would be first for me.  Now I do find a lot of bones in glacial deposit but not much worth sharing.  This piece is only 1 1/2 inch long.  Thanks.

This doesn't look like bone to me.

Looks more like a piece of chert.

The marks are just weathered fractures.

And radiocarbon dating is only accurate up to about 50,000 years. You suggest in your tabs that you think the rock is " probably Palaeozoic", so it wouldn't work. Even "ice age" material is mostly too old. 

So, you'd have to use something like uranium-lead or potassium-argon. 

The rock would therefore have to contain a radioactive element that has a measureable half-life, which is very unlikely. Usually, fossils and sedimentary rocks cannot be dated this way, so we have to look to igneous rock, such as granite, or volcanic ash layers above and below the sedimentary rocks (or in the middle of) to give us an age.

 

It looks like chert to me, too.

I don't see the conchoidal scars typical of chert, but it still looks like a quartz based hard stone...not bone, not teeth marks.  I agree with Tim regarding the fracture scars.

Thanks guys.  Just a tosser then.
