 The Spanish geologists Eladio Liñán and Rodolfo Gozalo argue that some of the fossils described in Greek and Latin lapidaries as scorpion stone, beetle stone, and ant stone, refer to trilobite fossils.Less ambiguous references to trilobite fossils can be found in Chinese sources.Fossils from the Kushan formation of northeastern China were prized as inkstones and decorative pieces.
