Ptyktoptychion - Chimaeroid

Fossil photo | Thu 19 Jan 2012  

Tooth plate of the extinct chimaeroid Ptyktoptychion (lower Gearle Siltstone). The genus was originally described from rocks of Albian age (~ 105 million years old) in Queensland. It is a very rare chimaeroid known only from three tooth plates (one from Queensland and two from the Giralia range, Western Australia) so we are much exited about this second find from WA.
