许德佑(1939～1944年)将贵州省西部三叠系“法郎组”称为“海燕蛤层”,定其时代为拉丁期。王义刚(1983)研究黔西南菊石时,把“法郎组”三分(竹杆坡段、赖石科段、龙场段),其龙场段的Trachyceras multitubertulatum菊石带被归入下卡尼阶。本文研究了产自贵州省关岭县—贞丰县三叠系“法郎组”上部(本文称瓦窑组,相当王氏的赖石科段)的菊石4属9种和鹦鹉螺类1属1种。研究结果表明,从这些菊石在国内外的地质地理分布和与其伴生的牙形石看,产出上述头足类的瓦窑组的时代确定为早卡尼期晚期是适宜的。
Xu Deyou (1939 ~ 1944) in the western Guizhou province Triassic “franc group” as “sea cocklebur layer”, set its period for the Latin period. When Wang Yigang (1983) studied the southwestern Guizhou ammonias, the Trachyceras multitubertulatum ammonoid belts belonging to the “Franc Group” three points (Zhupanpo Section, Lai-Shi-Ke Section and Longchang Section) Order. In this paper, 9 species of 4 genera of ammonites and 1 genus of Nautilus from the upper part of the Triassic “Franc Group” of the Guanling-Zhenfeng County, Guizhou Province (referred to herein as the Laiyake Section of the Waya Group) 1 species. The results show that from the geo-geographical distribution of these ammonites both at home and abroad and the associated conodonts, it is appropriate to determine the age of the Wayail Formation of the above-mentioned cephalopods as late Cretaceous.
