Oligocene to early middle Miocene period was characterised by an increase in the disparity of lanternfish but with a reduction in their otolith sizes. A second and persisting secular pulse in lanternfish diversity (particularly within the genus Diaphus) and increase in size begins with the "biogenic bloom" during the late Miocene, paralleled with diatom abundance and gigantism in baleen whales.
