Figure 3 in Notes on rhopalosomatid wasps of Dominican and Mexican amber (Hymenoptera: Rhopalosomatidae) with a description of the first fossil species of Rhopalosoma Cresson, 1865
Figure 3. Reconstructed chromatogram (m/z = 234 + 236) of Baltic amber (solid line) and Mexican sample (dashed line). The shift in the retention times of compounds XIIId and XIVd (Mexican amber) compared to IXd and Xd (Baltic amber) is due to the difference of configuration between the enantio and regular forms, which classifies the Mexican sample as a class Ic resinite. The box depicts the similar retention time for trimethylnaphthalene (m/z = 155).
