FIGURE 2. Austrosequoia novae-zeelandiae (Ettingshausen, 1887) Mays et al., 2017, PL1227. 1) Transverse section of a partially exposed, desiccated ovulate cone. 2) Neutron tomographic reconstruction largely encapsulated in sedimentary matrix, white indicates high neutron attenuation, oblique-transverse view. 3) Volume rendering of neutron tomographic reconstruction, RNA = Relative Neutron Attenuation, grid texture on RNA spectrum indicates relative transparency, regions of highest neutron attenuation represent in situ resin within cone axis and minor enclaves of resin near the distal ends of the bract-scale complexes, desiccation exhibited by large gaps in coalified organic remains (blue/green), oblique-transverse view. 4) Greyscale histogram from neutron tomographic reconstruction of PL1227 (16-bit) these values represent the neutron attenuation of the reconstructed volume, colours and transparency textures as per Figure 2.3, threshold values presented in Table 2, the spectrum has been cropped at the extremes for this graphical representation. See Appendix for an animation of the virtually extracted specimen illustrated in Figure 2.3.

FIGURE 1 in Challenges encountered during acid resin transfer preparation of fossil fish from Monte Bolca, Italy
FIGURE 1. Fourier-Transform Infrared spectrograph of the three existing polymers. Wavenumber refers to the wavelength of light and % Transmission refers to the amount of each wavelength that is transmitted through the sample. These are the parameters measured by the spectrometer to achieve an infra-red spectrum. Each peak is indicative of a different chemical bond and different substances will produce distinct patterns.
