I think the shiny surface is what they call "desert varnish". It is a common occurrence out in the arid areas, where the rocks on the surface develop a smooth shiny look. I don't think anyone has completely worked out why it happens yet, either. But take it to the museum anyway, they should soon sort it out for you.
