Materpieces scale model

Materpiscis was a ptycodontid placoderm that lived in the Late Devonian of Western Australia. It is only known from one fossil specimen, 28 centimeters long, but the curious thing about this one specimen is that a fossil embryo was found inside it. This implies that this placoderm gave birth to live young, much like two other species (Austroptychodus and Incisoscutum, also known from Western Australia). It appeared in Hell on Earth. (However, it lived 380 million years ago, much earlier than the time shown in the episode)

Hell on earthEdit

Materpiscis were initially seen finding food and giving birth to young fish. During the extinction event, it turned out that such a tactic of reproduction didn't work out for it, and it eventually went extinct.
