The attraction of the Spengler Museum is the skeleton of the steppe mammoth from Edersleben. It was excavated between 1930 and 1933 in a gravel pit near Edersleben by Gustav Adolf Spengler. The precursor of the woolly mammoth is a female specimen, for which an age of 45 - 50 years is assumed. It lived before the Elster glaciation about 500,000 years ago.
Further relics of a warm-age fauna that existed before the Elster glaciation were excavated from 1954 - 1963 in the Voigtstedt clay pit. Among the finds are the remains of rhinoceroses, sabre-toothed cats, giant deer and southern elephants.
In the Mammoth Hall, numerous fossils from the Ice Age are exhibited, which are often discovered as individual finds in the area around Sangerhausen. There is also information about the evolution of the mammoth and the course of the Ice Age in the Thuringian Basin.
