Superb Campo del Cielo iron meteorite (Argentina), boasting a beautiful sculptural 'arrowhead' shape and showing extremely well-formed regmaglypts: small thumbprint-like oval indentations that are unique to meteorites and caused by ablation in our atmosphere during flight. The complete individual weighs 239.2 grams and measures approximately 80 mm x 53 mm x 28 mm. The Campo del Cielo meteorite is believed to have fallen to Earth 5,600 years ago and was first discovered in 1576; it is one of the oldest known meteorites on Earth. Accompanied by a certificate of authenticity signed by Geoff Notkin of Aerolite Meteorites Inc. and the TV show Meteorite Men, as well as a specimen identification card.
