well i still got no idea what it is, my car is still running, i may wait till i get my car serviced and give the part to mechanic, maybe he can shed some light, and give the underbody of the car a going over to see if its got any lose parts

I really dont think its from the car, but it does resemble the outside half of a brake caliper. no way it would just fall clean off though, and they are usually curved a bit.
