Doleserpeton
''Doleserpeton'' is an extinct, monospecific genus of dissorophoidean temnospondyl within the family Amphibamidae that lived during the Upper Permian, 285 million years ago. ''Doleserpeton'' is represented by a single species, ''Doleserpeton annectens'', which was first described by John R. Bolt in 1969.〔Sigurdsen, Trond, and John R. Bolt. "The Lower Permian Amphibamid Doleserpeton (temnospondyli: Dissorophoidea), the Interrelationships of Amphibamids, and the Origin of Modern Amphibians." Journal of Vertebrate Paleontology. 30.5 (2010): 1360-1377. Print.〕 Fossil evidence of ''Doleserpeton'' was recovered from the Dolese Brothers Limestone Quarry in Fort Sill, Oklahoma.〔"The Lower Permian Amphibamid Doleserpeton (temnospondyli: Dissorophoidea), the Interrelationships of Amphibamids, and the Origin of Modern Amphibians." Journal of Vertebrate Paleontology. 30.5 (2010): 1360-1377. Print.〕 The genus name ''Doleserpeton'' is derived from the initial discovery site in Dolese quarry of Oklahoma and the Greek root "serp-", meaning "low or close to the ground". This transitional fossil displays primitive traits of amphibians that allowed for successful adaptation from aquatic to terrestrial environments. In many phylogenies, frogs appear as the sister group of Doleserpeton.
==Paleobiology==
Physical characteristics from fossil evidence of ''Doleserpeton'' indicate that they resembled modern newts and salamanders.〔 The overall size of ''Doleserpeton'' was relatively small in size, with an estimated body length of 55 mm(2.165 inches) from snout to tail. Morphological features of ''Doleserpeton'' indicated that they were quadrupedal with elongate bodies and a lizard-like appearance. Their overall body morphology included short limbs protruding from a 90 degree angle, long tails, and flattened skulls with blunt snouts. ''Doleserpeton'' may have had smooth, grandular skin to adapt to the transition from aquatic to terrestrial environments.〔 Fossil evidence and classification of ''Doleserpeton'' predicted that they transitioned through metamorphic stages throughout their life, but lived primarily on terrestrial land during juvenile and adult stages. Like their modern amphibious relatives Lissamphibia, ''Doleserpeton'' may have had to rely on the availability of a nearby water source during reproduction and larval stages.
