The earliest Carboniferous Amphibia now known, such as Anthracosaurus, are so highly specialized that I can by no means conceive that they have been developed out of piscine forms in the interval between the Devonian and the Carboniferous periods, considerable as that is.

I think they used to splash about the water and fly over the land during the carboniferous period; anyway, it doesn't matter. Of course you have seen pictures of reconstructed creatures such as the ichthyosaurus, the plesiosaurus, the anthracosaurus, and the thermosaurus? "I nodded, trying to keep my eyes from hers.
The Archegosaurus, which we have figured, and the Anthracosaurus, are forms which appear to have existed in great numbers in the swamps and lakes of the age. The fish of the period belong almost entirely to the ancient orders of the ganoids and placoids. Of the ganoids, the great megalichthys Hibberti ranges throughout the whole of the system.
