Abstract

Tentaculitoids have long been recognised as an enigmatic group of marine invertebrates that are widely distributed and highly diversified in the Silurian and Devonian strata. A tentaculitid assemblage is described herein from the Nagaoling Formation spanning the Lochkovian-Pragian boundary in Nanning, South China. Six new species are recognised: Tentaculitesbrevitenui n. sp., Lonchidium cylicus n. sp., Bicingulites nanningensis n. sp., Odessites aurisites n. sp., O. nahongensis n. sp. and Volynites nagaolingensis n. sp. are diagnosed. Two species Podolites sp. and Seretites sp. and one population Uniconus spp. are described in open nomenclature. All above tentaculitid genera can be detected in the Silurian strata from Sweden. The tentaculitids from South China allow transitional skeletal characters between benthic and planktonic tentaculitoids to be described, including conch size, conch wall thickness, septum number and the relationship between external and internal wall sculptures. The fossil assemblage, sedimentary rocks and taphonomic characters indicate that tentaculitids of Nagaoling Formation in South China were deposited in an outer shelf region with weak hydrodynamic condition.
