本文首次对贵州志留系牙形刺进行了研究,3500粒标本分属于42个属93个种.自下而上建立了 Spathognathodus obesus 组合带、第Ⅰ间隔带(A 带)、Spathognathodus parahassi-Spathognathodus guizhouensis 组合带、Spathognathodus celloni 组合带和第Ⅱ间隔带(B 带)等序列.根据与欧美同期牙形刺对比,认为前四个带属早志留世,B 带属中志留世早期。描述了新属7个,新种35个.
In this paper, the first study of the Silurian condyloma acuminatum in Guizhou Province was conducted, of which 3,500 specimens belonged to 93 genera and 42 genera.Spathognathodus obesus combinatorial band was established from bottom to top, with the first interval (A band), Spathognathodus parahassi-Spathognathodus guizhouensis assemblage, Spathognathodus celloni assemblage and Ⅱ interval (B zone) sequence.According to the concomitant conodont of European and American condoms, the first four belts belonged to the Early Silurian and the B belonged to the Middle Silurian. Seven new genera and 35 new species were described.
