Between Althaldensleben and Hundisburg, the remains of glacial mammals such as mammoth, woolly rhino, wild horse and wild cattle first came to light during gravel quarrying. The gravel layers of the Bebertal are from the Saale ice age (around 300,000 to 130,000 BC).
Already in 1805 Goethe admired this in one
Helmstedter Collection an elephant tooth originating from Althaldensleben.
In 1904 stone tools of the early Neanderthal man were first salvaged in the park gravel pit Hundisburg. 1921 followed one of the first in Germany found hand axes. Until the closure of the gravel pit, around 100 more flint artefacts were added. They are attributed to the Paleolithic Achenleén about 200 000 years ago.
After the gravel site had already come from the perspective of science, set in 2005 again excavations (joint project of the University of Tübingen and the State Office for
Archeology Saxony-Anhalt). Here could salvage 448 stone artifacts and 567 faunal remains
and be scientifically studied.
