Conodonts are of great importance in the biostratigraphy of Lower Permian deposits. Gondolelloides is one of the conodont genera typical for the Asselian-Sakmarian interval, Northern cool-water province. At present, the representatives of this genus are found in the different-phase deposits in nine sequences in Northern America, in two sequences in the Novaya Zemlya, in one well in the east of the Timan-Pechora province, in one sequence in Polyarny Urals and in two sequences in Southern Urals. All these finds of the Gondolelloides representatives are confined to the Upper Carbonaceous Upper Gzhelian stage in southern Urals and to the Upper Asselian - Lower Sakmarian stage in other regions. It is not improbable that the center of Gondolelloides origin was located in the southern part of the Paleourals basin from which they subsequently spread in more northern and western regions including the eastern shelves of Panthalassa. The above data show that using the representatives of the Gondolelloides genus for interregional and global correlations is not reliable. However Gondolelloides may be used for local and intrabasin correlations.
