一个由中国科学家领导的国际团队，在一枚罕见的琥珀中，首次发现一只史前海洋动物、已灭绝的乌贼近亲“菊石”，将有助更好地了解琥珀的形成，以及过去的生态系统提供宝贵证据。

根据中国科学院南京地质古生物研究所，周一（13日）在美国《国家科学院学报》杂志发表的报告阐述，研究人员在一枚重约6克，长33毫米、阔9.5毫米、高29毫米的白垩纪中期形成的缅甸琥珀内，发现内有“菊石”等至少40个动物个体。

据了解，琥珀是植物树脂经长期地质作用形成的化石，研究显示“菊石”的软体已经丢失，且壳体有破损，内部充满了细小的沙粒，反映该海洋生物死亡后，外壳可能被海浪冲上岸，再被琥珀包裹。

除了“菊石”，该估计已存在1亿年的琥珀内，还有多种海洋腹足动物、潮间带等足类动物、螨虫、蟑螂及蜘蛛等陆地生物。
