本文描述镇安、洵阳一带的中泥盆世床板珊瑚和刺毛虫类化石计9属、12种,其中包括6个新种。根椐化石组合特征,划分为二个组合:镇安一带以 Thamnopora reticulata- Crassialveolites yunnanensis-Scoliopora denticulata 组合为代表的时代属中泥盆世晚期;洵阳磨沟口以 Favosites goldfussi—Roemerolites qinlingensis—Chaetetes salairicus 组合为代表,其时代定为中泥盆世早期。
This paper describes the genera and genera of 9 genera and 12 species of Middle Devonian bedplate corals and ciliate fossils in Zhen’an and Xingyang areas, including 6 new species. According to the characteristics of fossil assemblages, the assemblage was divided into two groups: the Tuannian reticulata-Crassialveolites yunnanensis-Scoliopora denticulata assemblage represented the age of the Middle-Late Devonian, and the Favosites goldfussi-Roemerolites qinlingensis-Chaetetes salairicus As the representative of the combination of its age as early as the Middle Devonian.
