Glycymeris vestita(DUNKER)のコンキオリンの構造について

概要

論文の詳細を見る
The author found the following five main units in the conchiolin structure of living specimens of Glycymeris vestita. They are: 1) the canal or tubular structure developed through all of three layers ; 2) the twisted structure developed only in the outer layer; 3) the ladder-like structure developed only in the outer layer; 4) the stratified structure developed only in the inner layer; and 5) the feather-like structure developed in the inner layer. In contrast, the conchiolin left in the fossil shells of the same species from the Narita formation (Middle Pleistocene) loses its mechanical elasticity and connective nature through decalcification processes, then becomes very friable. The only durable structure left without destruction is the canal structure, but other four units are seriously damaged.
