Why this rock is probably not a meteorite:

1) There's no fusion crust. The surface is not smooth.

2) On the right, there's a big round clast. Other big round clasts have clearly fallen out. Meteorites don't ever have clasts this round. 

3) There are no kind of brecciated meteorites where, on a broken surface, the clasts stick out in positive relief (right) or where clasts easily pluck out, leaving a cavity (front). In a meteorite, the clasts and matrix have similar hardness, so a break goes right through as though the clasts weren't there. For example, see QUE 93069
What is it?

A conglomerate.
