Artifact identification and dating lab recommendation
Has anyone seen this type of tool before or know how it may have been used?
Can anyone recommend a C-14 dating lab?
Found this on my property, 6" underground; I was digging a trench for a drain pipe at the time. My property is an argilite quarry site, previously excavated by H. Mercer in 1892 and R. Jordan in 1988.

My initial thought is that it is simply a naturefact. I know the crossing lines look intentional, but I have seen "incising" that results from natural processes before - including roots cutting into soft stone, natural crystalline/weatehring differences etc. I would suggest getting it to a local geologist that could tell you more about the stone itself (is it argillite? I know that weather in strange ways but do not have much personal experience with it).
as for c14 labs - I have usually worked with Beta-Analytic, but there is a large listing of labs to check into at http://www.radiocarbon.org/Info/ . What do you have that might be datable - since the pictured item seems to be stone - it can not be for that.
Good Luck with your efforts.

Looks too symetrical to be naturefact; two well executed X's, etc. I take it this is wood? If so, any petrification to it?

I am planning to excavate a large rock pile on the property. There may be something dateable in that pile so I want to know about labs in advance. Thank you Dmack89 for the link.

Since you were seeking C14 labs, I thought the item to be of wood. The lines IMO appear to be man made. Especially if they wrap around. Possible that they might have formed due to being tied to something and the ties were stressed and shifted frequently grinding on the rock. Might be a weight tied to a net or machinery from 18th or 19th century???

The important question to ask when considering this possibility - has the location of the find ever been a plowed field?

Discing can wreck havoc on artifacts as well as "create" some. What makes me suspicious that this is not a disc type naturefact is that Dmack89 says the X's are continuous across the back. The probabiility of disc generated lines being continuous on both sides and with no apparent chipping is IMO rather low. Granted, argillite is often soft, but these lines do look a bit crisp and not the least bit rounded out or wallowed out in their cuts as one would expect from a disc cut on a stone this size. Wish we all had the 3D technology to "print" such items for personal viewing/handling!
