A recently discovered, thin, flanged, boat‐shaped australite weighing 0.711 grams and measuring 27.2 mm by 10.5 mm by 1.8 mm to 2.4 mm from Port Campbell on the south coast of western Victoria, Australia, consists of approximately sixty five to seventy per cent circumferential flange glass which is relatively smooth and attached peripherally to an elongated, flow‐lined central core. The form is a rare and unique specimen representing the final ablation product of an originally somewhat larger, thicker, elongated primary australite shape, probably a biaxial ellipsoid of revolution, that became modified by aerodynamical heating during non‐rotational, high speed transit through the earth's atmosphere.
