Description
''Gooloogongia'' was large in size (about 90 cm).

The fangs of ''Gooloogongia'' are sharp and needle-like, but they were probably not strong enough to penetrate the armor plating of small placoderms
Placodermi (from Greek πλάξ 'plate' and δέρμα 'skin', literally 'plate-skinned') is a class of armoured prehistoric fish, known from fossils, which lived from the Silurian to the end of the Devonian period. Their head and thorax were ...
