Like most bivalves, these molluscs were suspension feeders. They lived in the Devonian Period (416,0 ± 2,8 e 359,2 ± 2,5 mya). DescriptionThe valves of the shell of the species in the genus Panenka are relatively thin and somewhat elongated. Unlike most other bivalves, these species, as all the others in the subclass Cryptodonta, have no hinge teeth on their shells. DistributionThis genus has been found in the Carboniferous of Australia; Devonian of Australia, Colombia, the Czech Republic, France, Germany, Italy, Morocco, Spain, United States; Silurian to Devonian of Mauritania; Silurian of Algeria, the Czech Republic, France, Morocco, Spain, and Western Sahara.
