regmaglypt (plural regmaglypts)

  1. (astronomy, geology) A shallow indentation or pit on the surface of a meteorite, resembling a thumbprint impression in clay, created by ablation while falling in an atmosphere.

      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.

      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.
