A meteorite develops orientation when it experiences a period of stable flight through Earth’s atmosphere during which it is gradually sculpted into a more and more stable shape (cone or shield) through ablation. The resulting meteorite can show evidence of other features associated with ablation including flow lines, roll-over lipping and regmaglypts.
