EARLY LATE PERMIAN NAUTILUS IN CENTRAL JIANGXI

This paper describes eight species and five genera of early Late Permian nautiluses from Central Jiangxi,including seven new species and one new genus.A brief introduction to the nautiluses from the Leping coal measure was made.This coal measure produees abundant nautiluses displaying both straight and rotational shells with the latter predominating,suggesting that the latter occupies an important position in the early Late Permian nautilus fauna.
