鱼龙、恐龙和翼龙虽都属于爬行类,而且分别为中生代(距今2.45亿年至6 500万年)海中、陆地和空中的霸王,但它们属于不同的大类,鱼龙、蛇颈龙等属于爬行纲中的调孔(或阔弓)亚纲,而恐龙和翼龙属于双孔(或双弓)亚纲。由于鱼龙大多生活于较深的海域,因此,形成化石很少,人们对它不甚了解,报道的也罕见。但近年来,在贵州西南的兴义县、关岭布依族自治县等一带,在距今2.3亿年的三叠纪中、晚期薄层、中厚层的泥灰岩、灰岩中,发现了大量鱼龙、安顺龙、贵州龙、楯齿龙等海生爬行类,以及极为丰富的无脊椎动物,如菊石、双壳类、腕足类、牙形类、海百合、海参……及植物化石等,引起人们的极大兴趣。小小的偏远山区陡然热闹起来了,中国人、外国人纷至沓来。这一地区也迅速成为我国继云南澄江(寒武纪生物大爆发的澄江生物群就产于此)和辽宁义县(长毛、长羽毛的恐龙及大量古鸟类的热河生物群的所在地)之后的第三个世界级的化石宝库,通过这一宝库,人们终于能了解鱼龙及其他海生爬行类的更多真面目。
Although the dinosaurs, dinosaurs and pterosaurs are all reptiles, and are respectively Mesozoic (245 million to 65 million years ago) in the sea, land and air overlord, but they belong to different categories, dragon, snake neck Dragons and other belong to the reptiles in the hole (or wide bow) subclasses, and dinosaurs and pterosaurs belong to two-hole (or double bow) subclass. Since most of the fish and dragons live in deeper waters, there are few fossils, people do not quite understand it, and reports are rare. In recent years, however, in the middle and late Triassic middle-late Triassic marl and limestone in the areas of Xingyi County and Guanling Buyi Autonomous County in the southwest of Guizhou Province, A large number of fish dragon, Anshun dragon, Guizhou dragon, Tarsanosaurus and other marine reptiles, as well as extremely rich in invertebrates, such as ammonites, bivalves, brachiopods, dentals, sea lily, sea cucumber ...... and plants Fossils, aroused great interest in people. Small remote mountain suddenly bustling up, Chinese, foreigners after another. This area also quickly became the site of the Jehol Biota in China (following the Cambrian biological outbreak in the Chengjiang biota in Yunnan Province) and in Yixian County, Liaoning Province (the long-haired and long-feathered dinosaurs and a large number of ancient birds) ), The third world-class fossil treasure trove, through which people can finally learn more about the true colors of the dragon and other marine reptiles.
