It includes the mostly Carboniferous-Permian age Dvinosauria and the mostly Permian-Triassic age Stereospondylomorpha. The clade was named in a 2000 phylogenetic analysis of stereospondyls and their relatives. Limnarchia means "lake rulers" in Greek, in reference to their aquatic lifestyles and long existence over a span of approximately 200 million years from the Late Carboniferous to the Early Cretaceous. In phylogenetic terms, Limnarchia is defined as a stem-based taxon including all temnospondyls more closely related to ''Parotosuchus'' than to ''Eryops''. It is the sister group of the clade Euskelia, which is defined as all temnospondyls more closely related to ''Eryops'' than to ''Parotosuchus''. Limnarchians represent an evolutionary radiation of temnospondyls into aquatic environments, while euskelians represent a radiation into terrestrial environments. While many euskelians were adapted to life on land with strong limbs and bony scutes, most limnarchians were better adapted for the water with poorly developed limbs and lateral line sensory systems in their skulls. ==Description== Several characteristics unique to Limnarchia were identified when the clade was named in 2000. Most of these characteristics, called synapomorphies, relate to the shapes of bones on the underside and back of the skull. Limnarchian synapomorphies include the presence of a row of teeth stemming from the ectopterygoid bone on the palate, the maxilla bone touching the vomer near the edge of the palate (these bones are separated by an opening in euskelian skulls), and the lack of bony projections called denticles on the vomer. Other characteristic features of limnarchians include the extension of the lower jaw behind the jaw joint, and a small hole called the paraquadrate foramen at the back of the skull. The only limnarchian synapomorphy not found in the skull is the elongated shape of the interclavicle bone in the pectoral girdle.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Limnarchia」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
