Austroptyctodus
Encyclopedia
Austroptyctodus gardineri is a small ptyctodontid placoderm fish from the Upper Devonian Gogo Formation
of Western Australia. First described by Miles & Young (1977) as anew species of the German genus Ctenurella. Long (1997) redescribed the German material and found major differences in the skull roof pattern so assigned it to a ne wgenus, Austroptyctodus.This genus lacks spinal plates and has Ptyctodus type toothplates.
The most significant discovery about Austroptyctodus is that it has one specimen of amother with 3 unborn embryos inside her, showing that like Materpiscis
, also from Gogo, this genus was a live bearer,and reproduced by copulation.
