Each entry is accompanied by the author and date of availability, by the name of the type species, by a lithostratigraphic or biostratigraphic and geographic reference for the type species, by a family assignment and by an age indication of the type species at the Period level (e.g. MCAM, LDEV). A second listing of these names is taxonomically arranged in families with the families listed alphabetically, higher level classification being outside the scope of this work.

NORR¹, VINCENT L. SANTUCCI1 and JUSTIN S. TWEET2 1National Park Service. 1201 Eye Street NW, Washington, D.C. 20005; -email: [email protected]; 2Tweet Paleo-Consulting. 9149 79th St. S. Cottage Grove. MN 55016; Abstract—Trilobites represent an extinct group of Paleozoic marine invertebrate fossils that have great scientific interest and public appeal. Trilobites exhibit wide taxonomic diversity and are contained within nine orders of the Class Trilobita. A wealth of scientific literature exists regarding trilobites, their morphology, biostratigraphy, indicators of paleoenvironments, behavior, and other research themes. An inventory of National Park Service areas reveals that fossilized remains of trilobites are documented from within at least 33 NPS units, including Death Valley National Park, Grand Canyon National Park, Yellowstone National Park, and Yukon-Charley Rivers National Preserve. More than 120 trilobite hototype specimens are known from National Park Service areas. INTRODUCTION Of the 262 National Park Service areas identified with paleontological resources, 33 of those units have documented trilobite fossils (Fig. 1). More than 120 holotype specimens of trilobites have been found within National Park Service (NPS) units. Once thriving during the Paleozoic Era (between ~520 and 250 million years ago) and becoming extinct at the end of the Permian Period, trilobites were prone to fossilization due to their hard exoskeletons and the sedimentary marine environments they inhabited. While parks such as Death Valley National Park and Yukon-Charley Rivers National Preserve have reported a great abundance of fossilized trilobites, many other national parks also contain a diverse trilobite fauna.

Upper lower Cambrian (provisional Cambrian Series 2) trilobites are described from three sections through the Shuangyingshan Formation in the Beishan area, northwestern Gansu Province, China. The trilobite fauna is dominated by eodiscoid and ‘corynexochid’ trilobites, together representing at least ten genera: Serrodiscus, Tannudiscus, Calodiscus, Pagetides, Kootenia, Edelsteinaspis, Ptarmiganoides?, Politinella, Dinesus and Subeia. Eleven species are described, of which seven are identified with previously described taxa and four described under open nomenclature. The composition of the fauna suggests biogeographic affinity with Siberian rather than Gondwanan trilobite faunas, and the Cambrian Series 2 faunas described herein and from elsewhere in northwestern China seem to be indicative of the marginal areas of the Siberian palaeocontinent. This suggests that the Middle Tianshan–Beishan Terrane may have been located fairly close to Siberia during middle–late Cambrian Epoch 2.
