Heersumer layers

The Heersum layers are a Jura formation with peculiar sea animal fossils that were formed about 150 million years ago.

The geologist Karl von Seebach found this formation in 1864 in a quarry near the village of Heersum , a town in the municipality of Holle in the Hildesheim district of Lower Saxony . As part of a scientific study, he gave this rock formation the name Heersum Layers .

These layers from the Jura are composed of light-colored limestone and marl stones . They used to be mined in four large quarries north of Listringen and Heersum. The Hildesheim professor Emanuel Pfaff has collected rich fossil material from these layers over decades .
