Concordia (genus)
''Concordia'' is an extinct genus of Late Carboniferous captorinid known from Greenwood County, Kansas of the United States.
==Description==
''Concordia'' is known from the holotype KUVP 8702a&b, well preserved skull in dorsal view along with its counterpart, a partial preserved braincase in ventral view, and from the referred specimen KUVP 96/95, well preserved skull in ventral view and a poorly preserved dorsal counterpart. It was collected in the Hamilton Quarry, from the Calhouns Shale Formation of the Shawnee Group, dating to the Virgilian stage (or alternatively late Kasimovian to early Gzhelian stage) of the Late Pennsylvanian Series, about 300 million years ago. ''Concordia'' was originally thought to be the basalmost known member of Captorhinidae.〔 A novel phylogenic study of primitive reptile relationships by Müller & Reisz in 2006 recovered ''Thuringothyris'' as a sister taxon of the Captorhinidae, and therefore, by definition, ''Thuringothyris'' represents the basalmost known captorhinid.〔Muller, J. and Reisz, R.R. (2006). "The phylogeny of early eureptiles: Comparing parsimony and Bayesian approaches in the investigation of a basal fossil clade." ''Systematic Biology'', 55(3):503-511. 〕 The same results were obtained in later phylogenic analyses. ''Concordia'' is still the earliest known captorhinid as all other captorhinid taxa are known only from Permian deposits.〔
