Meteorites don't have layers and as a result don't have these type features. This is not a meteorite. It is a rock with desert varnish. Notice how bumpy the rock is instead of being smooth like the others. Features that indicate a rock is a meteorite.
Fusion crust is what forms as a meteor passes through the atmosphere.
It is the melted exterior of the meteor. Because meteorites are composed of different materials not all fusion crusts look the same. Once a meteorite is on the ground it starts weathering. This weathering causes an oxidation of the crust and it turns from black to brown in color. Depending upon the climate conditions where it falls this will take varying amounts of time.
