This is a possible meteorite, discovered in Hunter NY, at noon on August 17, 2007. Why a meteorite? This rock is dark and shiny on one side, but much less so on the reverse side (typical of a "fusion crust"). No other rock in the area looked like this one.
It features numerous regmaglypts (or "thumbprints") where less dense materials sloughed off as the meteorite entered Earth's atmosphere. The glypts are about the size of a human thumb which is typical for a 15 pound meteorite. (Bigger meteorites have bigger glypts).
Most meteorites have no "layers". Most moon rocks and lunar meteorites are brecciated (ie. they contain broken bits if one or more types of rock transformed into a new, solid mass). This possible meteorite could be the first example of a previously unknown type such as an earth stone that was ejected from our atmosphere during a major impact - such as the Chicxulub event.
Based on a basic ACTLABS report, one of the top lunar meteorite experts says it is black limestone. Another meteorite expert said it is brecciated basalt with lots of feldspar. The curator of a mineral museum says 80% chance this is a lunar meteor.
