两块蛇琥珀均距今约9900万年,其中包含着蛇骨骼的一块如小柠檬般大小。与其他脊椎动物化石相比,蛇的化石极为稀有。此前,科学家从未在琥珀中发现过蛇类。早期蛇类化石则比较破碎,提供的信息不多,比如1.67亿年前的安氏黎明蛇。

“另一件标本是含蛇皮的琥珀,相比较而言,含有蛇骨骼的琥珀更为重要。”该研究的发起者、中国地质大学(北京)副教授邢立达说,中国地质大学(北京)团队和“石探记”科学团队在2016年初陆续发现了它们,然后用显微CT做出了详细三维解剖结构。

  结果显示:更为重要的“蛇骨”琥珀中,连续蛇骨长4.75厘米,包括了约97枚椎骨、一些肋骨和皮肤。这些椎骨十分细小,最小的单块尾椎仅约0.35毫米长。它的尺寸和形态显示了其很可能是一个刚“破壳”的蛇宝宝。
