Eogyrinus
''Eogyrinus attheyi'' (from Greek ''eos'', meaning "dawn", and ''gyrinos'', meaning "tadpole") was one of the largest Carboniferous tetrapods, and perhaps one of the largest of its family, Eogyrinidae, at in length. ''Eogyrinus'' appears to have been a powerful swimmer that moved quickly through the water by swishing its long tail from side to side. It may have been a predator, lying in wait for prey in much the same way as a modern crocodile. It was a lightly built animal, weighing around . Although probably better at hunting in the water, ''Eogyrinus'' could probably have also made a grab for prey passing close by on land. Fossils of ''Eogyrinus'' are known from northern England.〔 Recent studies by Jennifer A. Clack suggest that the amphibian ''Pholiderpeton'' described by Thomas Henry Huxley in 1869 is the same animal as Eogyrinus. If this is so, then ''Pholiderpetons name takes priority. ==References==
