John asked all the right questions, and for how light/heavy it is, float in water. If it floats half out of water, then it's pretty light, if it floats almost all the wood in water, pretty heavy. If it sinks - well, then there's only a few woods it would be and I don't think none of those look like that. I agree with all, oak sure looks a lot like that, but then so do other woods.
