研究人员通过从头骨中提取少量样本来检测放射性元素铀的衰变率,进而缩小了时间窗口,

该方法表明这块头骨至少有14.6万年的历史,可追溯至更新世中期

古生物学家安东尼奥·罗萨斯称,研究人员可能对龙人头骨某些进化后的面部特征给予过多重视,

这些面部骨骼形态特征可能是从共同祖先那里继承的原始特征,

因此来自哈尔滨的龙人头骨可能与现代人类或者尼安德特人有关(这两个人类物种拥有共同祖先)

发现龙人头骨的男子是在哈尔滨东江大桥工作时发现的,研究人员为了进一步验证,进行了一系列地球化学分析,他们观察了X射线荧光(XRF)、稀土元素(REE)和锶同位素(锶的一种变体),从而调查该头骨独特的化学成分。
