Kyrinion
''Kyrinion'' is an extinct genus of baphetid tetrapod from the Late Carboniferous of England. It is known from a skull that was found in Tyne and Wear county dating back to the Westphalian stage. Along with the skull is part of the lower jaw, an arch of the atlas bone (the vertebra that connects to the skull) and a rib possibly belonging to a cervical (neck) vertebra. The type species ''K. martilli'' was named from this material in 2003.
== Description ==
The holotype skull of ''Kyrinion'' is well preserved with the back of the skull and both stapes, or ear bones, intact. The orbits, or eye sockets, are somewhat triangular in shape. Areas connecting the palate with the jaws and braincase make the skull inflexible. Lateral lines, used for sensory perception in aquatic environments, are present on the quadratojugal bone behind the eyes. The lower jaw lacks the distinctive features of some other baphetids, such as teeth on the parasymphysial plate, a piece of bone that overlies the dentary symphysis.
