CN多鳃鱼模式种由刘玉海于1965年首次记述；后续中国团队开展系统研究。
The type species Polybranchiaspis liaojashanensis was first described by Yuhai Liu in 1965, followed by systematic studies by Chinese teams.

Internal anatomy of the polybranchiaspids (Agnatha, Galeaspida)
Nature · 1979
依据已查看的本地出版物正文片段概括。
Summary based on the inspected sections of the downloaded publication.
主要发现 Key findings
矿物充填形成的多鳃鱼脑腔、神经与血管内模，使作者能与七鳃鳗、盲鳗及其他甲胄鱼作内部解剖比较。
Mineral replicas of polybranchiaspid brain cavities, nerves and vessels enabled comparisons with lampreys, hagfishes and other armoured jawless vertebrates.
结论 Conclusions
作者主张盔甲鱼是独立类群，并提出与七鳃鳗及骨甲鱼的联系；这是1979年的系统解释，应结合后续研究阅读。
The author recognized galeaspids as a distinct group and proposed links with lampreys and osteostracans; this 1979 interpretation requires later phylogenetic context.

研究早期无颌与有颌脊椎动物的辐射，并非多鳃鱼的直接描述。
Analysis concerns early jawless and jawed vertebrate radiations, not a direct description of Polybranchiaspis.
主要发现 Key findings
新整理的古生代脊椎动物出现记录、生物地理与生态系统数据库显示，晚奥陶世大灭绝后，有颌类及相关无颌类在隔离避难所中发生平行的地方性辐射，恢复过程中包含较长的低多样性阶段。
New databases of Palaeozoic vertebrate occurrences, biogeography and ecosystems indicate parallel endemic radiations of jawed and related jawless vertebrates after the Late Ordovician mass extinction. Recovery took place in isolated refugia and included a prolonged low-diversity interval.
结论 Conclusions
大灭绝及其后的地理隔离参与塑造早期脊椎动物多样化；生态恢复与扩散限制可能解释了有颌类在颌首次出现很久之后才取得优势。
Mass extinction and subsequent geographical isolation helped structure early vertebrate diversification. Ecological recovery and dispersal constraints may explain why jawed vertebrates became dominant long after jaws first appeared.
