文中简要回顾大古油栉三叶虫属Megapalaeolenus是否是有效属的有关讨论。对罗惠麟等(2014)《再论大古油栉虫属Megapalaeolenus》一文做了简要评述,再次从定量分析角度,研究我国Palaeolenus fengyangensis带的palaeolenid类三叶虫分类。其所获得的结论与笔者(2004,2009)从定性分析和林天瑞(2014)应用聚类分析对我国palaeolenid类三叶虫分类及其生物带划分的结论完全一致,即Megapalaeolenus是Palaeolenus的晚出异名,应予废弃;Megapalaeolenus带无效,所在层位属Palaeolenus lantenoisi带。
The paper briefly reviews the discussion whether Megapalaeolenus is a valid genera or not. A brief review was made on the article “Megapalaeolenus” by Luo et al. (2014). From the perspective of quantitative analysis, the palaeolenid trilobite classification of Palaeolenus fengyangensis in China was studied again. The conclusions obtained are consistent with the conclusion of the author (2004, 2009) that the clustering analysis of palaeolenid trilobites and the zonation of their zonules in China are based on the qualitative analysis and Lin Tianrui (2014), that is, Megapalaeolenus is Palaeolenus’ Name, should be abandoned; Megapalaeolenus band invalid, the layer is Palaeolenus lantenoisi belt.
