恐龙蛋化石是非常珍贵的古生物化石,所见到的一般都是蛋的钙质外壳,极少发现保存有某种恐龙胚胎化石的蛋,很难判断所发现的蛋化石是由哪类恐龙产的。因此,在很长的一段时期内,有关恐龙蛋化石的研究工作并没有取得重要的进展,此枚恐龙蛋化石特别之处在于它已经快破壳而出之际,因为某些不可抗拒因素,终未出世,便长埋于地底深处,经过数亿年的等待,以另一种形式展现在世人眼前,历经上亿年沧海桑田演变的稀世珍宝,是生物和人类进化史上具有重要意义的科学标本,是世界上珍贵的科学和文化遗产。

  

  

中国科研人员对恐龙蛋进行研究后认为,由于在晚白垩世最后20~30万年间,南雄地区恐龙的生活环境发生了“突变”,严重的干燥气候以及微量元素的污染,锰、锌、锶等微量元素不足或过多,影响了恐龙蛋壳的正常发育,形成了病态蛋壳结构,因而恐龙蛋不能正常孵化,最终导致了恐龙的绝灭。所以恐龙蛋化石对于探索恐龙的繁殖行为、恐龙蛋壳的起源和演变,复原恐龙时代的生态环境;对于研究恐龙的出现、繁盛和绝灭;对于划分和对比白垩纪地层以及确定地层的地质年代;对于研究古气候、古地理和古生物的变迁,提供找矿启示等,都是不可多得的珍贵实物资料。

  

  

因此,恐龙蛋化石具有十分重要的科学价值、观赏价值、收藏价值。我们必须十分珍惜和保护恐龙蛋化石及其赋存的地质环境。

  

  Fossilized dinosaur eggs are very precious paleontological fossils, what we can see is generally the calcified shell of the egg, and it is very rare to find the egg preserved with some dinosaur embryo fossils, and it is difficult to judge the egg fossils found by what kind of dinosaur produced. So, in a long period of time, research work about the dinosaur egg fossil is no important progress was made, the pieces of dinosaur egg fossils so special is that it has been quickly hatched, because some irresistible factors, he was not born, long buried in deep underground, after hundreds of millions of years of waiting, in a different form to show in front of the world, These rare treasures, which have undergone hundreds of millions of years of changes, are scientific specimens of great significance in the history of biological and human evolution, and are the world's precious scientific and cultural heritages.

  Chinese researchers think that after the study of dinosaur eggs, due to the late cretaceous last 20 ~ 300000, the southern male "mutation" dinosaurs living environment and serious pollution of dry climate, and trace elements, the microelement such as manganese, zinc, strontium with insufficient or too much, affecting the normal development of the dinosaur eggshell and formed the pathological shell structure, As a result, dinosaur eggs could not hatch properly, which eventually led to the extinction of the dinosaurs. Therefore, dinosaur egg fossils can help to explore the reproductive behavior of dinosaurs, the origin and evolution of dinosaur eggshells, and restore the ecological environment in the age of dinosaurs. For the study of the emergence, prosperity and extinction of dinosaurs; For the division and correlation of the Cretaceous strata and the determination of the geological age of the strata; They are rare and precious material materials for the study of paleoclimate, paleogeography and paleontological changes, and for providing prospecting enlightenment.

  Therefore, dinosaur egg fossils have very important scientific value, ornamental value, collection value. We must cherish and protect dinosaur egg fossils and their geological environment.
