This is a Museum that most tourists overlook simply because they don't know it's there. You don't have to be a Geologist to understand and appreciate the many and varied displays. Each subject is explained in terms that even us 'laymen' can understand. This page concentrates on the fossil finds in Namibia. The museum's geological samples and history presentation are excellent and we soon hope to develop a page that will do it justice.

Pleistocene / Holocene (1,81 Ma to 10,000 years)
This Brain Cast of Orange River Man (100,000 to 50,000 years ago) shows well developed blood vessels in the parietal region of the skull and less clear development on the frontal lobes which is indicative that hearing and vision were extremely important for these archaic homo sapiens.
The fossilized remains of the below replica prosauropod dinosaur, Massospondylus were discovered in the Etjo sandstone formation at the National Waterberg Plateau Park in 1999. Massospondylus is of one of the oldest known of dinosaurs and grew to a length of about 6 m. As can be seen the forelegs, although used for walking on, are much shorter than the hind legs. It is thought that this dinosaur could have also walked and run by using just its hind legs. The blade-like teeth were used for slicing through the vegetation that it ate, indicating its food source was at ground level. Massospondylus also swallowed small pebbles to assist in the digestion of its food, in a similar way to some modern day birds, e.g. Ostrich. It was many millions of years later that the more well known of dinosaurs achieved their massive size.
Triassic Period (251 - 200 million years ago) Kannemeyeria : A mammal-like reptile herbivore common in Namibia some 230 million years ago and this is the largest known skull of the species. The snout was beak-like and was accompanied by two tusk like canines that extended below the upper jaw. The head weighed +-15kg and the large flanges at the rear of the head are for the massive neck muscles .
The below fossil of a Mesosaurus tenuidens was found in a band of Karoo Sequence Limestone in the southern Karas Region of Namibia. Mesosaurus tenuidens was the
earliest of the reptiles that returned to living in the water. Following the time of the melt of the Great Gondwana Ice Age a large inland sea formed across where large areas of the the South African Karoo, Southern Namibia, Brazil and Uruguay used to be
Several excellent examples of Mesosaurus can be seen on the farm Spitzkoppie about 45 km north west of Keetmanshoop .
The Air That We Breath: The oldest known of fossils in the world are of the green-blue algae known as cynobacteria that lived at the edges of the ancient oceans as early as 3,500 million years ago. These simple algae increased to be the dominant life force on the planet for most of the Eon of time known as the Proterozoic , and derived their energy from the sun's rays by the process of photosynthesis. 3,000 Ma ago the earth's atmosphere was rich with carbon dioxide and devoid of oxygen, but over a period of 1 billion years the activity of these small algae had increased the
activity of these small algae had increased the atmosphere's oxygen content to about 20% which in turn allowed for more complex life forms to evolve. These algae with their glutinous sheaths as protection grew in colonies and carpeted the sea bed. Grains of sand would cling to the sheath's and eventually block the sun's light from them. The algae's survival response was that of growing up through the layer of grains in order that they could continue with the process of photosynthesizing. This pattern of early life continued over hundreds of millions of years and eventually led to the building of the great carbonate mountain chains. The fossilized remains of these algae 'constructions' are named Stromatolites and represent the some of the oldest of all fossils. Good examples 830 to 760 Ma can be found in the Otavi Mountains of northern Namibia.
