Negatives of the tracks

In 2008, the silicone mould that had been left on the third expedition in 2007 to save the raptor tracks, was finally dry. The mould could be loosened carefully by the scientists: the result was a splendid series of footprints. The complete tracks were outlined with chalk, photographed and then the entire series of tracks (60sqm) was traced with a water-proof pen on transparency.
