When a Billion Years Disappeared

Synopsis

The Great Unconformity, a significant geological feature, reveals a gap of approximately 1.2 billion years in Earth's history, with rocks below it being much older than those above. This missing period may be associated with the breakup of the supercontinent Rodinia, extensive glaciation, and the early diversification of life. The exploration of these geological phenomena provides insights into the planet's evolutionary timeline and the environmental changes that shaped it. Produced in collaboration with PBS Digital Studios, the documentary highlights the importance of understanding Earth's complex history.
