直接研究鸿鱼的论文超出当前登录账户的访问权限，已保留引文，无法下载 PDF。论文摘要描述的是晚泥盆世鱼类，而工作簿记为早泥盆世。
The direct Hongyu paper is outside the current signed-in account access. Citation retained; PDF unavailable. Its abstract describes a Late Devonian fish, whereas the workbook says Early Devonian.
主要发现 Key findings
鸿鱼兼有根齿鱼与希望螈类、四足动物特征；贝叶斯与最简约分析对其亲缘关系给出不同结果。
Hongyu combines rhizodont and elpistostegid–tetrapod traits, with Bayesian and parsimony analyses producing different relationships.
结论 Conclusions
结果支持更广泛的平行演化或需修订的近缘关系，显示四足动物干群演化复杂且存在不确定性。
The findings imply extensive parallelism or revised relationships and expose uncertainty in the tetrapod stem-group tree.
