c.380 million years ago, Late Devonian (Frasnian), The Kimberleys, Western Australia

When myself, John Long and Kate Trinajstic described Gogosardina coatesi("Mike Coates's Gogo Sardine") in 2009, it represented the first Gogo ray-finned fish to be described in over 30 years. A comparatively rare species, it is only known from about half a dozen specimens. It was a slender fish, about 12 cm long, that was closely related to "Mimia". It differed in having much smaller scales and in details of the skull roof, snout and parasphenoid. At least one specimen is known to have died while eating a conodont animal (the conodont elements are lodged in the gill arches, suggesting a prey animal almost as big as the gluttonous fish). Either the fish choked or suffered a ruptured gut.
