The authors erect Costatoria costata var. subrotunda (Bittner) from Hungarian Lower Triassic to species level. Its subgeneric position is also discussed here. Thus, Costatoria is represented in the Werfen Formation of Dolomites area by two species: C. (Costatoria?) subrotunda (Bittner) from the upper part of Campil Member (Smithian) and C. (Costatoria) costata (Zenker) from Cencenighe and S. Lucano Members (Spathian). C. subrotunda shows a wide geographic distribution and could be considered as a helpful marker of Smithian age.-Authors

Abstract
The authors erect Costatoria costata var. subrotunda (Bittner) from Hungarian Lower Triassic to species level. Its subgeneric position is also discussed here. Thus, Costatoria is represented in the Werfen Formation of Dolomites area by two species: C. (Costatoria?) subrotunda (Bittner) from the upper part of Campil Member (Smithian) and C. (Costatoria) costata (Zenker) from Cencenighe and S. Lucano Members (Spathian). C. subrotunda shows a wide geographic distribution and could be considered as a helpful marker of Smithian age.-AuthorsFile in questo prodotto:
