This is probably discussed in the following paper:
Parker, A.R. 2000 "515 Million Years of Structural Colour". Journal of Optics
A: Pure and Applied
Optics 2(6).

Diffraction grating studies have provided a lot of colour information for
extinct animals over the
years, with Andrew Parker being one of the more prolific authors. See also:
