Megamastax (meaning "big mouth") is a genus of lobe-finned fish which
lived during the late Silurian period, about 423 million years ago, in
China. Before the discovery of Megamastax, it was thought that jawed
vertebrates (gnathostomes) were limited in size and variation before the
Devonian period. Megamastax is known only from jaw bones and it is
estimated that it reached about 1 metre (3 ft 3 in) long.

With rounded coronoid teeth, Megamastax could have fed on hard-shelled
animals.

Fossils of Megamastax were found at Kuanti Formation in Qujing, Yunnan, China.
