恐龙——一类早已灭绝了的古爬行动物,生活在距今2.25亿年～0.65亿年前的大陆上,曾经统治地球达1.6亿年之久。在距今约6500万年的白垩查纪末期,恐龙神秘而突然地从地球上消失,不仅给科学界留下了一个难解之谜,同时也使它成为全人类最感兴趣的话题之一。人类发现恐龙化石的历史已有180多年,在世界各大洲(包括南极大陆和北极的某些岛屿)都能看到恐龙留下的痕迹。我国是世界恐龙大国,恐龙化石的产地很多,已发现的恐龙属种达100多个,在恐龙的2目24科中我国几乎都有代表。除了恐龙化石,我国的恐龙蛋化石也非常丰富,在16个省、区都有发现,尤其是1993年～1996年在河南西峡、内乡、湖北郧县等地发现的数万枚恐龙蛋化
Dinosaurs - a class of already extinct ancient reptiles, lived 225 million years ago ~ 665 million years ago on the mainland, once ruled the earth for 160 million years. The mysterious and sudden disappearance of dinosaurs from the earth at the end of the chalk dating of about 65 million years ago not only left a mystery for the scientific community but also made it one of the most interesting topics for all mankind . It has been more than 180 years since the discovery of dinosaur fossils in the world. Traces of dinosaurs can be seen on all continents of the world, including some in the Antarctic continent and some in the Arctic. China is a world dinosaurs powerhouse. Dinosaur fossils have many origins. More than 100 dinosaur species have been discovered. Almost all of China has representatives of 2 dinosaurs and 24 families of dinosaurs.
