Fig 7 — The geological time scale and evolution of fishes. indicate global anoxic events (after Takashima et al., 2006) when the deep sea is unlikely to have been habitable by fishes. Deep-sea bottom temperatures are indicated by the and scale on the left (Schopf, 1980). Times of divergence of the major classes, subclasses and divisions of fishes are taken from recent literature. indicate the probable pattern of colonization of the deep from shallow seas but with localized and global extinctions in the deep. ? indicate putative pre-Cretaceous colonisation for which there is no direct evidence.
