      But, as the author has established, when an individual sample of a meteorite shower has a semi-orientated shape (roughly conoid, as in the given case), it must have definite morphological properties: on its front surface it must have a fully developed typical regmaglypt - relief which has had time to form during the sample's movement at cosmic speed after its separation from the main meteoric body.
    • 1965 June 1, “Advances in Meteoritics in Western Australia”, in Meteoritics, volume 2, number 4, page 318:
      This, the Warburton Range meteorite, weights 125 lbs and is a single mass displaying regmaglypt patterns on its surface.
    • 1994, O. Richard Norton, Rocks from space: meteorites and meteorite hunters, page 141:
      The largest Henbury meteorites show beautiful regmaglypt structures. Some are oriented, displaying a shieldlike form produced when a meteoroid passes through the atmosphere without tumbling and ablates, primarily on the leading side.
