Interesting information in the Paleobiology section:
Like other large primitive temnospondyls, Eryops would have grown slowly and gradually from aquatic larvae, but they did not go through a major metamorphosis like many modern amphibians. While adults probably lived in ponds and rivers, perhaps venturing onto their banks, juvenile Eryops may have lived in swamps, which possibly offered more shelter from predators.
Paleobiology is an interdisciplinary field that combines the methods and findings found in both the earth sciences and the life sciences. Paleobiology is not to be confused with geobiology, which focuses more on the interactions between the biosphere and the physical Earth.
