Figure 8 in Revision of Eocene electric rays (Torpediniformes, Batomorphii) from the Bolca Konservat-Lagerst atte, Italy, reveals the first fossil embryo in situ in marine batoids and provides new insights into the origin of trophic novelties in coral reef fishes
Figure 8. Visual image of the principal component analysis (PCA) performed on the entire set of log-transformed standardized morphometric and meristic features, showing the separation of the specimens referred to †Titanonarke molini (right side of morphospace) from those referred to †Titanonarke megapterygia sp. nov. (left side). The illustrations lying along the extreme values of PC1 represent the hypothetical reconstruction of the two species based on body proportions.
