Argentinian palaeontologist and geologist Teresa Manera de Bianco is struggling to save a unique collection of animal footprints made 12,000 years ago. The three-kilometre-long site is now part of the Atlantic coastline near Teresa’s home, but 12,000 years ago it was an inland pond teeming with birds and mammals. Covered for thousands of years by sediment, the site is today under threat from rising sea levels and thousands of tourists. Confronting technical challenges and government bureaucracy, Teresa is racing against time to preserve the footprints in latex casts that will provide scientists with important clues about the life of animals that once roamed the pampas.
