Special Stamps from April 17 to June 16, 1990 100 Years Museum of Natural History Berlin In 1890, the natural history collections of the University of Berlin, combined in the Museum of Natural History, began to make their exhibition rooms accessible to the public in the then newly constructed building. On the special postage stamp series issued for this occasion, some of the dinosaur finds from the Tendaguru strata of East Africa are shown, which also contributed to the attractiveness and the international reputation of the museum. From 1909 to 1912, an expedition of the museum was able to carry out very successful excavations, to whose finds the dinosaur skeletons depicted belong. Dinosaurs have been the dominant animal group on Earth for more than 150 million years. In the Jurassic and Cretaceous periods, their development with giant shapes reached a climax. 25 Pfennig value: Kentrurosaurus aethiopicus HENNIG, 1915 The shape of the 4.70 m long dinosaur from the group of the Ornithischians can not be reconstructed without doubt. There is still no reliable knowledge about the position of the bone plates and spines on the body and on the mode of locomotion. The dentition in the relatively small skull indicates that this animal was an herbivore. Similar to this African form are the stegosaurs of North America. The skeletons from Africa are unique in the world.
