Аннотация

The structure and microstructure of the shell substance Acrotretella sp. on the protegulum, brephic and adult shell. The structure of the secondary layer, represented by interlayers with columnar-lamellar and spherulite structures, is characteristic. Wrinkles are developed along the edges of the shell.
