Fossils embedded in South African rocks that date back 320 million years offer evidence of lobe-finned fish (the same family as coelacanths).

"This glimpse into the early life history of ancient coelacanths raises further questions about the life history of the modern coelacanth, Latimeria, which is known to bear live young, but whether they, too, are clustered in nurseries remains unknown," explains Coates.
Yet more subfamilies (Aqp15 and -16) have been identified in non-mammalian vertebrates, including lampreys (Hyperoartia), sharks (Chondrichthyes), ray-finned fishes (Actinopterygii), coelacanths (Actinistia), frogs (Amphibia), alligators (Crocodylia), and turtles (Testudines) (Finn et al., 2014).
A vast river network there had once nourished coelacanths, sharks, crocodile-like predators and dinosaurs.
At the time, a variety of aquatic life populated the system, including large sharks, coelacanths, lungfish and crocodile-like creatures, along with giant flying reptiles and predatory dinosaurs.
Coelacanths resemble the fossilised skeletons of their ancestors from more than 300-million years ago (Figure 2).
Kerstin Lindblad-Toh, senior author of the paper, said: "Coelacanths are likely very specialised to such a specific, non-changing, extreme environment - it is ideally suited to the deep sea just the way it is."
Coelacanths are native to the Comoro Islands, and the ROM was fortunate to acquire a frozen specimen from the New York Aquarium's 1985 expedition there.
