古生物钟也称化石钟,是指古代生物化石身上所保留的生物生长的节律,它给我们带来了丰富的信息。一、古生物钟忠实地记录着古气候、大陆漂移的历史。在20世纪30年代初,留日的地质学家马廷英发现古生代早期的四射珊瑚化石上,有反映气候季节性变化的生长线,记录了寒季生长缓慢、生长纹密集;暖季生长迅速、生长纹稀疏的事实。1935年,他在研究了东沙群岛的造礁珊瑚以后认为:无论古代的四射珊瑚化石或是现代的造礁六射珊瑚,其组织内部和外部都有日生长现象和季候生长现象。随后他就发表专著提出: The paleontological clock, also called the fossil clock, refers to the rhythms of biological growth preserved in the ancient biological fossils. It brings us abundant information. First, the ancient circadian clock faithfully records the ancient climate, the history of continental drift. In the early 1930s, Ma Tingying, a Japanese geologist, discovered that there are seasonal growth lines on the coral fossils in the early Paleozoic. They recorded the slow growth and dense growth patterns in the cold season, the rapid growth in the warm season, The fact that sparse growth patterns. After studying the coral reefs of the Dongsha Islands in 1935, he considered that both ancient and emerging reef coral fossils have daily and seasonal growth both inside and outside the organization. Then he published a monograph put forward:
