A very strange find.

Found this in a dry river bed in north Scottsdale az. Very strange and there is like a crust of rusty metal on the back like its burnt. It's has little crystals and shiny goldish flakes everywhere around the iron crust on back and it's magnetic. Possible meteorite

? Really cool rock

Have seen this before with a UT geology prof on a field trip. Think it's a fossil clam shell with deposition of iron pyrite on it. The iron rusts, the pyrite shines...

that would be cool but this is def a stone completely solid and very dense rather heavy for its size

It is attracted by a magnet?

Lots of rocks are attracted by a magnet, but few are magnetic.
To test for magnatism hang a needle by a thread and see if the needle moves when the rock is brought near.
If it does then your rock is magnetic.

I think you may have misunderstood my question. Using an independent magnet of some sort, will the magnet pick up your item?

If so, there is a slight possibility that you have a meteorite. There is a chance that the crust may be fusion crust created by extreme heat as the object interred the atmosphere.
