Society for the Study of Amphibians and Reptiles exchanges and international cooperative efforts for study and publications. The society was founded as a regional organization, The Ohio Herpetological Society (OHS), by two young but serious-minded amateurs, Kraig Adler and David M. Dennis, then 16 and 17 years of age respectively. They decided in the fall of 1957 to formalize interactions amongst a small group of amateur herpetologists throughout Ohio and began publishing a combined journal and newsletter (called the "Trimonthly Report") in January 1958. The name of the society was changed to The Society for the Study of Amphibians and Reptiles on January 1, 1967. The SSAR publishes
Evolution of reptiles in the past. Reptiles have an extremely diverse evolutionary history that has led to biological successes, such as dinosaurs, pterosaurs, plesiosaurs, mosasaurs, and ichthyosaurs. Reptiles first arose from amphibians in the swamps of the late Carboniferous. Increasing evolutionary pressure and the vast untouched niches of the land powered the evolutionary changes in amphibians to gradually become more and more land-based. Environmental selection propelled the development of certain traits, such as a stronger skeletal structure, muscles, and more protective coating (scales) became more favorable; the basic foundation of reptiles were founded. The evolution of lungs and legs are the main transitional
