The occurrences of these species are confined to the upper sublittoral Anadara-Neogenella association. The upper sublittoral zone of cold-water embayment acts as one of the ecological refuges due to the high primary production rate and the lower predation pressure than in the warmer seas.}, pages = {1--13}, title = {内湾性貝化石群集と残存種の関係 : 長野県北部の鮮新統城下層産貝化石群}, volume = {59}, year = {1995}, yomi = {アマノ, カズタカ and サトウ, ハルキ} }
