Microphotographs showing the locations of Raman spectra: (a) microphotographs of a middle leg of the specimen showing the thin layer coating the fossil. Photo by B. Rondeau. (b) Raman spectrum of the matrix with peaks characteristic of opal-CT35. (c) Raman spectrum of the black carbon-rich material inside the coating. (d) Raman spectrum of the thin layer showing features of clinoptilolite–heulandite zeolite. Our Raman spectra are shown in black; in grey—a reference sample38. (Op opal contribution).
