Buettneria Diplovertebron ops). This large amphibian is found in the Permian beds of Texas, and as may be seen, it was a strong, heavy, land-living animal. Here was the high point in amphibian evolution. Look at En/ops and you see the culmination of development in the Am- phibia, an animal that was a truly dominant element in his environment. All that went before was building up to this climax in amphibian history, all that has come since is in a sense an anticlimax. There were various amphibians^con- temporaneous with Eryops. Some of them were small, active labyrinthodonts^JOthers were not labyrinthodonts at all, for at that time there were several lines of amphibian development evolving side by side. Per-

haps one of the most interesting of the non-labyrinthodont forms was Diplocoulus (3I(>1o-kawl-us^ belonging to a group known as the Nectndia. This was a peculi- arlyHat, wide, water-living amphibian with an extraordinarily bizarre skull, shaped somewhat like a tremendously broad arrow- head. The ancestry of our modern amphibians, though obscured in the mists of geologic time, is probably dual in pattern. There is indication that the frogs and toads are de- scended from a labyrinthodont stem, while the salamanders and perhaps the coecilians are derived from certain small, salamander- like amphibians of Pennsylvanian age known as lepospondyls (lep-o-spoN-dils). 44
