From the Aquatic to the Terrestrial Environment; the Tetrapoda

  • Jean Chaline


During the later stages of the Devonian, osteolepiforms, doubtless much like Eusthenopteron or the Panderichthyidae, acquired characteristics allowing them to live, at least partly, in a continental environment. These were the first tetrapods. For these aquatic animals to be able to live in a terrestrial setting, it was necessary for them to acquire a certain number of adaptations relative to various vital functions: respiration, resistance to desiccation, locomotion, and reproduction.
