广州东朝文化：稀世珍宝——恐龙蛋化石
化石就是生活在遥远过去的生物遗体或遗迹变成的石头。在漫长的地质年代里，地球上曾经生活过无数的生物，这些生物死亡之后的遗体，或生活时遗留下来的痕迹，许多都被当时的泥沙掩埋起来。
A fossil is a stone formed by the remains or remains of a creature that lived in the distant past. In the long geological age, there have been countless creatures living on the earth. Many of the remains of these creatures after their death, or traces left in their lives, were buried by the sediment at that time.
恐龙是卵生生物，在其灭绝时除了留下化石的骨骼外，还有未被破坏的恐龙蛋，成为考古学家研究这古老生命的重要资料，也是现代人类对探索过去历史的重要途径之一。下图为藏友刘先生带来的一款双体恐龙蛋化石，价值更是难以估量。
Dinosaurs are egg-bearing creatures. In addition to the remains of fossils, there are still undamaged dinosaur eggs when they are extinct. It has become an important material for archaeologists to study this ancient life and one of the important ways for modern humans to explore the past history. The figure below shows a double dinosaur egg fossil brought by Mr. Liu, a Tibetan friend. Its value is even more incalculable.
恐龙蛋化石的大小悬殊，小的直径在3cm左右，大的直径可达56cm。蛋化石的形状通常为卵圆形，少数为长卵形、椭圆形和橄榄形。恐龙蛋中最珍贵的品种是含有胚胎的恐龙蛋，中国是世界上恐龙蛋化石埋藏异常丰富的国家，无论在品种上、还是数量上，都令世人瞩目。
