Dialipina
Dialipina is an extinct genus of prehistoric marine bony fish from the Early Devonian. It contains two species, both known from the high Arctic of Asia and North America. It was initially thought to be and sometimes still is treated as an early, basal actinopterygian, but recent phylogenetic analyses suggest that it may instead be a stem-osteichthyan.
The following species are known:
- †D. markae Schultze, 1992 - Lochkovian of Kotelny Island, Russia
- †D. salgueiroensis Schultze, 1968 - Emsian of the Northwest Territories, Canada
