BMNH PM1343B 保存部分关节相连骨架，原研究将其归入约 1.60 亿年前的髫髻山组并恢复为基干真兽类；产地、年代用途和拓扑仍有条件限制，无约束尖端定年则估算出早白垩世的形态年龄信号。

Primary Bayesian tip-dating sensitivity analysis; its unconstrained age estimate is a model output, not a redating of the rock specimen.

Juramaia sinensis 由正模 BMNH PM1343B 及原研究约 1.61 亿—1.59 亿年前的髫髻山组归属有条件地约束；不确定的采集产地和更年轻的尖端定年信号，使该区间不能被视为可靠全球首现或校准点。
