In September, I spent three weeks in Newfoundland, Canada working on world class Ediacaran fossil surfaces with Emily Mitchell, Charlotte Kenchington and Lucy Roberts. After eight hours of travelling, our bright red truck full of precision equipment, people and food arrived in the town of Portugal Cove South. We settled into ‘The Green House’, where we would be staying, and promptly collapsed in bed.
The Archean Eon (4–2.5 billion years ago) is one of the last great frontiers in our knowledge of the Earth. Plate tectonics is considered to have initiated during this time period, and large volumes of the continental crust formed, but fundamental questions remain regarding the timing, mechanisms and drivers of these transitions.
