They are, therefore, both a local highlight of the geological succession but have an important position within the history of geology. Formed in the tropical seas of the Middle Devonian, 10°S of the Equator, they also demonstrate the history of Devon in terms of Continental Drift and Plate Tectonics. Caves in these limestones provide an important record of both marine and terrestrial Pleistocene history, including some important hominin remains.
