Description:

This very popular book is an account of Twyfelfontein's geological development in earliest times to the population of the area by prehistoric creatures and primeval forests.

This is followed by an account of the arrival of man on the scene and his contribution to the landscape. The creatures that early man carved onto the ancient rocks are the animals he shared the land with.

Many of these animals were still there in recent times. Today, from the slopes of Twyfelfontein the visitor gazes over an ancient landscape and sees a flat, featureless valley surrounded by flat-topped mountains.

Yet, Twyfelfontein has a history that goes back to a time when no living creature walked the planet. The oldest underlying rocks at Twyfelfontein are metamorphic schist. Some 550 million years ago, before the continents we know today existed, two minicontinents, the Kalahari and Congo cratons, collided.

The impact caused the land to fold and form a huge mountain belt. Former marine sediments, which had been deposited into a trough between these two minicontinents, were subjected to deformation. The heat generated by the collision transformed them into metamorphic rocks. […]
