中新社南宁8月1日电 (张广权)广西民族博物馆8月1日介绍,由中国、法国、荷兰多国学者联合开展的现生动物模拟实验研究,证实了豪猪活动是华南及东南亚喀斯特洞穴化石埋藏的关键影响因素。该研究构建了亚洲豪猪对动物骨骼改造的判别标准,破解了长期争议的洞穴堆积成因问题,相关成果已刊发于国际权威期刊《考古科学杂志:报告》。
华南与东南亚喀斯特洞穴保存有大量含猿类、古人类等第四纪哺乳动物化石,是研究早期人类起源与扩散的关键材料。但该区域化石多为零散牙齿、完整骨骼稀缺,这个埋藏学问题长期困扰着学界。近年来,科学家通过观察化石表面的大量动物咬痕,将目标锁定在中国南方和东南亚广泛分布的穴居动物豪猪身上。
论文第一作者、广西民族博物馆副研究馆员姚艳燕介绍,研究团队通过对豪猪投喂现生动物骨骼,观察豪猪收集、搬运、啃咬骨骼的行为模式,并收集被啃咬后的骨骼及脱落的零散牙齿。将实验获得的材料与化石标本比对,发现化石表面的啃咬痕迹、齿根残缺、环状肢骨等改造特征,均与豪猪啃咬痕迹高度吻合。
在实验中,豪猪表现出明显的骨骼收集行为,能协作拖动超过5千克的牛头骨,它们会持续啃咬头骨直至剩下坚硬的牙齿从头骨中散落。这解释了为何在洞穴中会发现亚洲象、野猪和猕猴等不同体型动物的牙齿化石。
姚艳燕推断,数万甚至数百万年前,作为次级消费者的豪猪,将肉食动物遗留下来的动物遗骸搬回洞穴啃咬以摄取营养物质,遗骸中的坚硬部分(如牙齿)则被遗弃,并逐渐埋藏起来。
论文通讯作者、山东大学教授王伟说,这项研究有助于古生物学家理解东亚南部和东南亚地区喀斯特洞穴化石的形成原因,还可以帮助考古学家区分早期人类是否在洞穴化石的累积过程中发挥过作用。相对于非洲已建立的第四纪成熟的埋藏学框架,本项研究填补了东亚及东南亚大陆上重要洞穴遗址研究的一项空白。(完)
