Products description
This is a beautiful cluster with 6 echnoid fossils of the species Conulus subrotundus from the Wuellen Formation. The renowned site at the Hollekamp quarry in Ahaus-Wüllen was especially famous for its fossil "battlefields" of fossil sea urchins of the species Conulus subrotundus. Due to the partially slightly condensed sediments at this fossil site, these remarkable fossil clusters could form. Apparently, the lighter components of the still unconsolidated sediment were partially washed out, while the heavier sea urchin shells were swept together into depressions. These clusters of echinoid fossils are actually a local uniqueness. They were not that very rare at the time of active limestone mining. Today, the site is considered virtually extinct, and the quarry has been renaturalized. So new finds are unlikely. | |||
