Neodrepanura is an extinct genus of damesellid odontopleurid trilobite.
Taxonomy
[edit]Species of Neodrepanura are better known under the older synonym, Drepanura: the genus was renamed as Neodrepanura in 2006 by Özdikmen when "Drepanura" was discovered to be preoccupied by a springtail described by Schoett 1891.[1]
Fossil record
[edit]The various species of Neodrepanura are known from numerous, mostly disarticulated fossils found in Late Cambrian-aged marine limestones of Eastern and Southeastern Asia, especially of Northern China.[1] The genus ranged from about 501 to 497 million years ago during the Guzhangian faunal stage of the late Cambrian Period.
Description
[edit]The pygidia, particularly those of N. premesnili, are mined by the Chinese for use as "bat stones" or "swallow stones," as good luck charms and traditional medicines.[2][3] In 2011, the first intact specimen of N. premensnili was found in the Kushan Formation, enabling researchers to better examine the external anatomy of the genus.[1]
