Scientific breakthroughs can happen in the strangest ways and places. Alexander Fleming discovered penicillin because of mould growing on a Petri dish left out while he was on holiday. Chinese monks in the 9th century wanted to make a potion for immortality: instead, they discovered gunpowder.
Our own remarkable discovery happened on a rugged, remote stretch of coastline east of Still Bay on South Africa’s Cape south coast. It was low tide, and three members of our ichnology team (people who study tracks and traces) were in search of newly exposed Pleistocene vertebrate tracksites in aeolianites (cemented dunes).
