Scientists studied the Tasman Fracture , a deep trench in the ocean . And , because the coral 's uranium decays into thorium over time , it is conveniently datable . The researchers found that it was not just an anomaly but actually part of a larger pattern of tectonic activity on Earth. Discoveries included a new anemone , the sea squirt and a new kind of barnacle .
