@roger,
Looks like a "meteorwrong" . REndy Korotev , a geochemist at the U of St Louis is probably your best source for submitteing pictures for a best nalyses of m,eteorites.
A meteorite usually has a strong "reaction surface" and conchoidal pits that result from the rock enetering our atmosphere and oxidizing in a rough ride in.
Yours looks just like some fractured black rock, maybe goethite or goethite hematite or even magnetite.
hqrd to tell from photos what it is, But I think we can say what it isnt.
