Pretty sure that's not part of the meteor in queston. My understanding is that significant oxidation on the surface only happens if a meteorite is exposed to atmosphere for some time lying on the ground. I could be wrong, I am only an amateur enthusiast, but the pitting on surface also makes me wonder as the outside would normally be relatively smooth having been molten only moments before impact.

Bassikounou, ordinary chondrite (H5), S2, W0
Bassikounou, Hodh Ech Chargui, Mauretania. Fell October 16, 2006, 04:00hrs.
TKW: ~ 37kg, individual 308.00gm. (Classification submitted by B. Hofmann, NMBE, publication pending)

Organic and irregular specimen with a number of gorge shaped regmaglypts. This particular meteorite was collected the morning after the fall and shows no signs of terrestrial oxidation. The velvet textured fusion crust is dull black and embeds a number of blank spots where melted iron concretions formed small bumps protruding through the fusion crust.
