Okay, here's an idea-- the meteorite looks to be filled with cracks-- maybe heat
managed to flow through one of the pre-existing seams and get deeper into the
meteorite than it ordinarily would, and surround bits of the matrix from behind.
I know I have (and probably most of you have) fully-crusted individuals with
deep (but still crusted) grooves in them that apparently formed by burning into
cracks in the material.
