Gooloogongia lived during the Late Devonian period (Famennian stage, about 360 million years ago).
[1] Fossils have been found in the Canowindra site, (Australia).
In general size and shape Gooloogongia is similar to the modern saratoga which lives in the tropical rivers of northern Australia.
Gooloogongia loomesi ("Loomes' Gooloogong") named after Bruce Loomes, the foreman of the 1993 excavation of the Canowindra site, and the town of Gooloogong, NSW.
The fangs of Gooloogongia are sharp and needle-like, but they were probably not strong enough to penetrate the armor plating of small placoderms.
