A Review of Volkhovian and Kundan (Arenig-Llanvirn) Nautiloids from Sweden nautiloids assigned to the Ellesmerocerida, Endocerida, Actinocerida, Dissidocerida, Orthocerida, Tarphycerida and Oncocerida. Several taxa are key in deciphering the evolution of Ordovician cephalopods, especially early Oncocerida, Endocerida and Orthocerida, and provide further evidence for the systematic position of the lituitid nautiloids.作者: 沉思的魚 時(shí)間: 2025-3-23 00:29
