Abstract
The "nacreous" luster characteristic of the pholidostrophiid group of fossil brachiopods results from a shell structure that produces superimposed sets of natural optical-diffraction gratings made of calcite. The wall structure is crossed lamellar, parallel to the shell surfdce; thus flakiness and development of reflecting surfaces are facilitated.This publication has 2 references indexed in Scilit:
