The Kassel Sea Sand or Kassel Formation is a formation of the lower Chattium ("Eochattium") of Central Europe. The name refers to the type locality on the banks of the Ahne near Kassel in northern Hesse .

References

The slopes of the Ahna consist of shell limestone and tertiary sand . This layer is covered with tuff and basalt . About 60 million years ago, large masses of water flooded the Kassler basin and formed a lake , which then flowed off to the north, leaving behind salt water .

Because the ancestors covered the igneous rock that only appeared later , they washed out the protected sea ​​sand . The sand in the stream bed and the sandy bank is a Tertiary and Oligocene site of numerous fossils.

Finds of the same age come from e.g. B. also from Glimmerode and an important site is in Kaufungen .

Finds

Among the findings include white seashells, foraminifera , fossilized snails and iron brown colored tone in which one even fossilized fish invertebrate, Gehörst A (otoliths) of fish and shark fish teeth found. Exemplary finds are exhibited in the Natural History Museum in the Ottoneum in Kassel . Erwin Busse and Julius Görges were collectors of the location .
