The taxonomic divisions presented primarily by God in the Bible differ in part from the Linnaean classification system, which is familiar to modern biology. An evaluation was completed of the usage of the Hebrew terms for each division during the Creation week, after the Fall, during the Flood, and later in Biblical history. The analysis suggests that dinosaurs declined significantly after the Fall and before the Noachian Deluge. Conversely, after the Fall, mammals increased markedly. This conclusion runs contrary to other creationist theories that suggest that most dinosaurs died during or after the Flood. The Bible suggests these trends may have occurred for theological reasons: the danger that dinosaurs posed to the existence of mankind, their susceptibility to demonic influence, and their capabilities under infernal control.
