土地殖民化是一个重大的进化转变。在埃迪卡拉纪到奥陶纪期间陆地入侵的漫长前奏之后，古生代的其余部分经历了多样性的爆炸性增长以及底栖生物群通过创建新的生态位扩展到新的环境。这种扩张从沿海地区发展到河流、洪泛区、沙漠和湖泊，并增加了动物生态空间的殖民化。出现了一种模式，在新环境的殖民化之后，可用的生态空间迅速填充，之后动物建立新的行为程序。这些项目最初以原始建筑设计的创建为代表，随后通过代表这些既定主题的变化的大量的icnogenera进行修改。总体模式与已针对各种动物和植物进化枝确定的多样化的早期突发模型一致，其中存在解耦，因为差异的初始扩大随后是多样性的增加。
The colonization of land was a major evolutionary transition. Following a protracted prelude to the terrestrial invasion during the Ediacaran to Ordovician, the remainder of the Paleozoic experienced an explosion of diversity and the expansion of benthic biotas into new environments through the creation of new niches. This expansion progressed from coastal settings into rivers, floodplains, deserts, and lakes, as well as increasing colonization of infaunal ecospace. A pattern emerges in which colonization of a new environment is followed by rapid filling of available ecospace, after which animals establish new behavioral programs. These programs are represented initially by the creation of original architectural designs, and subsequently modified by a proliferation of ichnogenera representing variation upon these established themes. The overall pattern is consistent with the early burst model of diversification that has been identified for various animal and plant clades, wherein there is a decoupling as an initial expansion in disparity is followed by an increase in diversity.
