Meteorite or meteo-wrong?

Hello everyone.
I found this strange rock on a beach today. On it's surface there's something that looks to me like a fusion crust (although since I'm not an expert I might well be wrong). It also attracts a magnet glued to a piece of a string. Could it be a meteorite?

@patrykw,
Don't know, but a heck of a good title.

@patrykw,
Never seen fusion crust on a concave surface before. That seems a bit suspicious.

@rosborne979,
We have several in our museum collection taken from York Peninsula during the Amundsen expedition in the early 1900's.
Is it strongly magnetic?(addressed to OP).Ie does it cause the string to hang strait out asif the magnet were hanging like a hammock?

Since youve used the meteorite/meteowrong terms, I assume you know the guys at ST Louis Wash University (I have a reference somewhere here).

Hes yer best source. Meteroite hunting is like snarfling for mushrooms.

@farmerman,
No, it's just slightly magnetic. I tried again with a small neodymium magnet and it does stick, but barely. A ferrite magnet I tried on it before won't hang at all. It falls off when the string is inclined about 45 degrees.
And unfortunately I don't know anyone at St Louis Wash University. I'm in central Italy Smile

@patrykw,
Randy Korotev is a meteorite specialist . Hes a lunar geologist . You can google him and send him the picture of your rocks with the reaction skin and those little indents (we call em regmoglypts).
Im thinking these are rocky meteorites because the magnetism isnt that extreme.
An Fe/Ni would yank a magnet off the refrigerator and itd be hard to unstick it from the meteorite. Good luck with Randy, hes in touch with folks from all over the planet.

Hes got a weird ense of humor so dont be put off. Hes got a web page about mteorites and he includes some instructions if you insist on contacting him.
