中国早、中泥盆世地层含有相当丰富的鹦鹉螺类化石,但经研究和记述的属、种并不多。其实,在早泥盆世埃姆斯期、中泥盆世艾菲尔期和吉维特期地层内现都采到了丰富的标本,它们在地层分布上有一定规律可循,可作为地层对比的手段之一。本文描述的材料各自采于广西和湖南早、中泥盆世地层内,共计有10个属、14个种、1个未定种和1个属、种未定,其中包括1个新属和14个新种。 As early as in China, the Middle Devonian stratum contains quite a large number of nautilus fossils, but not many species and species have been studied and described. In fact, in the Early Devonian Ames Period, abundant samples were collected in the Middle Devonian Eifelian and Gewitt formations. They have some regularities in stratigraphic distribution and can be used as stratigraphic contrast One of the means. The materials described in this paper are collected in the early and middle Devonian strata in Guangxi and Hunan Province, and there are 10 genera, 14 species, 1 undetermined species and 1 genera, including 1 new genera and 14 species New species.
