Moeraki Boulders, South Island, New Zealand  7 Jan 2025

Are you ready to rock the new year? Today is Old Rock Day, a day for celebrating and learning about old rocks and fossils. Although rocks are common, few of us take the time to consider how amazing they are. Forged in volcanoes or moulded by millennia of pressure, these solid masses of minerals hold the key to understanding how our planet formed. Rocks can also contain fossils, the remnants of long-extinct organisms, which give scientists clues about what creatures and plants have lived on Earth during its 4.5-billion-year history. The United Kingdom, with its rich geological diversity, provides a front-row seat to the ancient forces that shaped our planet. On the Jurassic Coast in Dorset and East Devon, rocks over 180 million years old tell tales of dinosaurs, ancient seas and volcanic activity. And don"t forget the Giant"s Causeway in Northern Ireland, with its impressive columns of basalt.
