Miocene-Period Freshwater Fish Had Opportunistic Benthopelagic Diet

Paleontologists from the Australian Museum Research Institute, the University of New South Wales, the University of Canberra and CSIRO have described a new species of osmeriform fish from the fossilized remains found in New South Wales, Australia; preserved stomach contents of the fish indicate an opportunistic benthopelagic diet, evidenced by the remains of numerous phantom midge larvae, two insect wings, and a bivalve.
