Cochlioceras Eichwald (1860) |
Cochlioceras is an extinct baltoceratid genus from the lower and middle Ordovician ( Arenig - Llanvrin) of what are now Europe, the U.S. (Vermont), and China, having existed for approximately 14 million years, from about 478 to 464 mya. [1]
Cochlioceras was named by Eichwald (1860). Its type is Cochlioceras avus. It was assigned to the Baltoceratidae by Furtnish and Glensiter in Teichert et al. (1964) [1] and removed, with the Baltoceratidae, from the Ellesmerocerida to the Orthocerida by Kroger et al. (2007) [2]
