摘　　要：20世纪90年代以来,随着中国和阿根廷等地大量的恐龙蛋化石(特别是包含有胚胎化石的标本)被发掘出来,恐龙蛋的研究取得了长足进展。获得的信息说明,恐龙是高度分异的庞大多样化种群,不仅它们的体形差异巨大,而且其蛋的形态、尺寸及产卵习性也有很大差别。在形态和尺寸上,有大小如鸡蛋、柚子、篮球、铁饼及橄榄球等;产卵习性上,有一次产多枚,杂乱堆积掩埋;也有一次产两枚,精心排列成圈等。It has fairly progressed the research on fossil dinosaur eggs with abundant specimens （ especially, the embryos in the inner of eggs）unearthed from China, Argentina and otherwhere since 1990s. Discoveries of fossil dinosaur eggs show that dinosaurs were diversiform creatures, and their differences greatly not only on appearance, but also on shapes and size of their eggs and behavior of these animals laying eggs. The shapes and sizes of the fossil eggs include chook egg-like, shaddock-like, basketball-like, discus-like, American foothall-like and such. On behavior of dinosaur laying eggs, some of dinosaurs laid multi eggs at a time and buried them intricately, other ones laid two eggs at a time, arranged and imbedded them elaborately.
