TABLE 1. Taxonomic study history of palaeolenid trilobites from the Guanshan Biota.
PublicationSpecies consideredRelevant notesMansuy (1912, p. 27)Palaeolenus douvillei, P. deprati and P. “lantenoisi ”First description of three Palaeolenus species using a few specimens (n =6) with all the cranidial features exhibitingChang (1966, p. 150).Megapalaeolenus depratiMoved Palaeolenus deprati into MegapalaeolenusChang et al. (1980, p. 234, pl. 73, figs 9-12)Palaeolenus longispinusErected Palaeolenus longispinus using robust pleural spines on second thoracic tergiteLin and Peng (2004)Megapalaeolenus deprati and Palaeolenus douvilleiDoubted the validity of Megapalaeolenus. Noted that holotype was deformed and considered M. deprati conspecific with Palaeolenus douvilleiLuo et al. (2007)Megapalaeolenus deprati, Palaeolenus douvillei and P. “lantenoisi ”Considered all species and genera to be validLin and Peng (2009)Megapalaeolenus deprati and Palaeolenus douvilleiConsidered species conspecificHu et al. (2013)Megapalaeolenus deprati, Palaeolenus douvillei, P. “lantenoisi ” and P. longispinusSuggested all taxa were valid speciesLin (2014)All the published 34 specimens assigned to palaeolenids (n=34)Used cluster analysis to group all taxa into Palaeolenus. Suggested P. douvillei and Megapalaeolenus deprati conspecificLuo et al. (2014)Palaeolenus douvillei and Megapalaeolenus depratiConsidered both taxa valid. Noted they are found in different members of the Wulongqing FormationLin and Peng (2016)All the published 34 specimens assigned to palaeolenids (n=34)Used cluster analysis to group. Reconfirmed Lin (2014), suggesting Palaeolenus douvillei and Megapalaeolenus deprati are conspecific
表1 关山生物群(Guanshan Biota)古莱氏三叶虫类(palaeolenid trilobites)的分类学研究史
| 发表文献 | 涉及类群 | 相关研究说明 |
| :--- | :--- | :--- |
| Mansuy(1912,第27页) | 道氏古莱氏虫(*Palaeolenus douvillei*)、德氏古莱氏虫(*P. deprati*)及*P.* "lantenoisi" | 首次利用6件标本(*n*=6)对3种古莱氏虫属(*Palaeolenus*)物种进行描述,完整记述了其全部头甲结构特征。 |
| Chang(1966,第150页) | 德氏大古莱氏虫(*Megapalaeolenus deprati*) | 将德氏古莱氏虫移至大古莱氏虫属(*Megapalaeolenus*)中。 |
| Chang et al.(1980,第234页,图版73,图9-12) | 长刺古莱氏虫(*Palaeolenus longispinus*) | 依据第二胸节肋叶上的强壮肋刺,建立长刺古莱氏虫新种。 |
| Lin and Peng(2004) | 德氏大古莱氏虫与道氏古莱氏虫 | 对大古莱氏虫属的分类有效性提出质疑,指出其正模标本存在变形,并认为德氏大古莱氏虫与道氏古莱氏虫为同物异名。 |
| Luo et al.(2007) | 德氏大古莱氏虫、道氏古莱氏虫及*P.* "lantenoisi" | 认为所有涉及的物种与属级分类单元均为有效类群。 |
| Lin and Peng(2009) | 德氏大古莱氏虫与道氏古莱氏虫 | 认定上述两个物种为同物异名。 |
| Hu et al.(2013) | 德氏大古莱氏虫、道氏古莱氏虫、*P.* "lantenoisi" 及长刺古莱氏虫 | 提出所有分类单元均为有效物种。 |
| Lin(2014) | 所有已发表的34件归入古莱氏三叶虫类的标本(*n*=34) | 采用聚类分析将所有类群归至古莱氏虫属,并提出道氏古莱氏虫与德氏大古莱氏虫为同物异名。 |
| Luo et al.(2014) | 道氏古莱氏虫与德氏大古莱氏虫 | 认为两个分类单元均为有效,并指出二者发现于五龙青组(*Wulongqing Formation*)的不同地层成员中。 |
| Lin and Peng(2016) | 所有已发表的34件归入古莱氏三叶虫类的标本(*n*=34) | 采用聚类分析进行类群划分,再次验证了Lin(2014)的结论,提出道氏古莱氏虫与德氏大古莱氏虫为同物异名。
