Why this rock is probably not a meteorite:

There's no fusion crust.

Notice that the clasts are all the same kind of rock and that they stand out in positive relief compared to the matrix. These features don't occur in meteorite breccias because the matrix and clasts have the same hardness in meteorite breccias. Also, there are a lot of big clasts and no small clast. That also doesn't occur in lunar or asteroidal breccias.
What is it?

Probably another pebble conglomerate. The clasts look like they could be chert, a form of quartz.
