地球生命起源于海洋,绝大多数动物经过数亿年的繁衍,终于成功登陆,呼吸到第一口由陆地植物制造的氧气。但每当陆地上的生存压力巨大时,动物们就只有两条路可以选择:一是继续坚守在陆地上;二是把目光转向波澜壮阔的大海。神龙入海爬行动物下海大猜想在距今约2.51亿年前的二叠纪末期,地球上发生了有史以来最为惨烈的生物大灭绝。这个时期,大陆漂移过程正好处于“拼合”的状态,世界正在形成一块巨型完整的“泛大陆”。 Earth’s life originated in the sea, the vast majority of animals after hundreds of millions of years of reproduction, and finally successfully landed, breathing the first oxygen produced by land plants. But each time there is a tremendous pressure of survival on land, there are only two ways for the animals to choose from: one is to stay on land; and the other is to turn their attention to the magnificent sea.

During this period, the process of mainland drift was exactly in the state of “flattening” and the world was forming a giant complete “pan-continental”.
