An Entity of Type: building, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The Walcott–Rust quarry, in Herkimer County, New York, is an excellent example of an obrution (rapid burial or "smothered") Lagerstätte. Unique preservation of trilobite appendages resulted from early consolidation (cementation) of the surrounding rock, followed by spar filling of the interior cavity within the appendages. The presence of so many well preserved trilobites in one location alone qualifies the beds as an exceptional trilobite site, but the beds are further distinguished as the source of the first trilobites for which appendages were definitively described.
