Jurassic Ink

This sketch of Belemnotheutis antiquus may not be the most inspiring work of art I've ever posted on Coxsoft Art News, but for palaeontologists it is a knockout. The ink used is about 150 million years old! It was taken from the ink sac of a fossilised squid which lived in the Jurassic period. When palaeontologists from the British Geological Survey cracked open the fossil, which was unearthed during a dig in Trowbridge, Wiltshire, they found that the ink sac was still soft and contained ink fit for drawing this sketch.
