Your mystery object has a better chance of being identified if you also include the following...
Multiple clear, various angle pictures... with a reference item for size IE: Coin, soda can, etc.
Information as to a general location where the item was found IE: Woods, Beach, desert etc.
An idea of its composition. IE: is it metal ? Is it magnetic ? can many times either lead to... or be the main part of solving the puzzle.
A size (dimensions).
A weight if possible... or even a guestimate.
Any and ALL marks... if any.
In other words... when posting an item in hopes of identification VIA Tnet / us... these things are almost always detrimental to its identification.
Sorry I'm new. Found it along a road in Northern New Mexico along a 1/4-1/2 mile long out cropping of granite/Quartz/mica/pyrite and all kinds of other unknown. Guess it's called a stoneworks? Has veins of Quartz, veins of sandy dirt and veins of some blackish crusty rock running though it.
