. "The Messel Pit (German: Grube Messel) is a disused quarry near the village of Messel, (Landkreis Darmstadt-Dieburg, Hesse) about 35 km (22 mi) southeast of Frankfurt am Main, Germany. Bituminous shale was mined there. Because of its abundance of fossils, it has significant geological and scientific importance. After almost becoming a landfill, strong local resistance eventually stopped these plans and the Messel Pit was declared a UNESCO World Heritage site on 9 December 1995. Significant scientific discoveries are still being made and the site has increasingly become a tourism site as well."@en . . "The oil shale was actively mined from 1859. The pit first became known for its wealth of fossils around 1900, but serious scientific excavation only started around the 1970's, when falling oil prices made the quarry uneconomical. Commercial oil shale mining ceased in 1971. The land was slotted for use as a landfill, but the plans came to nought, and the [[Hessian stat bought the site in 1991 to secure scientific access. In the few years between the end of mining and 1974, when the state started preparing the site for garbage disposal, amateur collectors where allowed to collect fossils. The amateurs developed the \"transfer technique\" that enabled them to preserve the fine details of small fossils, the method still employed in preserving the fossils today. Due to the extraordinary fossils, the pit was declared a UNSCO world heritage site in 1995. Many of the known specimens from the site have come from amateur collectors, and in 1996, an amnesty on previously collected fossils was put in effect, in the hope of getting privately owned collections back into public ownership and available to science."@en . . .
