Microstructure and growth of the lenses of schizochroal trilobite eyes [PDF]
Lenses within the schizochroal eyes of phacopine trilobites are made principally of calcite and characterisation of them using light microscopy and high-resolution electron imaging and diffraction has revealed an array of microstructural arrangements ...
