关岭新铺晚三叠世早期卡尼期(Carnian)龙层及其下伏竹杆坡组上、中部的腕足类从上到下可划分为Linguloid,Laballa,Pseudokoninckina等3个化石群落。根据各群落特征分子的固着方式、生活习性、贝体形态和大小,以及与其他生物共同埋藏情况,并考虑围岩性质等方面的综合因素,得出Pseudokoninckina群落的古生态底域位于BA4内侧至BA3外侧,Laballa群落的古生态位置相当于BA2,而Linguloid群落则为BA1。在此基础上进一步阐明关岭新铺从竹杆坡组中部至龙层呈现明显海退过程,其古生态底域位置从BA4内侧至BA3外侧一直退到BA1。依据此变化绘出新铺卡尼期海平面下降示意图。对创孔海百合被一些学者推断为假浮游的生活方式提出质疑和讨论,得出当时创孔海百合不可能为假浮游的生活方式,它们应是营底栖的。
The upper and middle brachiopods of the Late Carnian Dragon Layer of the Late Triassic and the underlying Zhushangpo Formation of the Late Triassic can be divided into three fossil communities, Linguloid, Laballa and Pseudokoninckina, from top to bottom. According to the fixation methods, living habits, body shape and size of shellfish, and burial with other organisms, considering the characteristics of surrounding rock and other factors, the paleoclimate bottom of Pseudokoninckina community is located inside of BA4 In the outer BA3, the paleoenvironmental position of the Laballa community is equivalent to BA2, while the Linguloid community is BA1. On the basis of this, it is further clarified that the Guanling new shop shows a clear regressive process from the middle part of the Zhupanpo Formation to the Longtong Formation, and its palaeo-ecological bottom position has retreated to BA1 from the inside of BA4 to the outside of BA3. Based on this change, draw a map of the decline of the Shin-Chan Khanian sea level. It was questioned and discussed by some scholars that the fake seaweed lily was assumed to be a pseudo-planktonic life style. It was concluded that it was impossible for fake seaweed to be a planktonic lifestyle at the time, and they should be benthic habitats.
