Figure 11 in Revision of the Eocene 'Platyrhina' species from the Bolca Lagerst atte (Italy) reveals the first panray (Batomorphii: Zanobatidae) in the fossil record
Figure 11. Comparative strict consensus trees from parsimony analyses run in PAUP showing the hypothetic relationships of †Eoplatyrhina gen. nov. and †Plesiozanobatus gen. nov. (in bold) among batoids. A, consensus tree of total dataset with suprascapular coding according to Compagno (1999) and to Da Silva et al. (2018); B, consensus tree of total dataset with suprascapular coding according to Compagno (1999) and Da Silva et al. (2018) with the exclusion of character 85 and excluding Heterodontus + Squalus (-HS). Dashed line from Hexanchidae represents a polytomy recovered in CH, compared to DS. Grey inset indicates the section of the tree with most variability, as it relates to the position of Rajidae. Numbers above branches reflect the Bremer support. Closed circles = Torpediniformes; open circles = Platyrhindae; closed triangle = Zanobatidae; open triangle = Myliobatiformes + Zanobatidae; upside-down open triangle = Myliobatiformes; closed rectangles = Rajiformes; open rectangles = Sclerorhynchoidea; open diamond = Rhinopristiformes; open J = Jurassic batoids. See Table 1 for all tree statistics and see Supplemental material, File 1, Fig. S1 for all characters mapped in support of tree B.

FIGURE 2. Composite time-stratigraphic chart of the Neogene of Nebraska correlated with the number of snake genera presently identified from the Central Great Plains for each North American Land Mammal Age (NALMA) substage. Abbreviations: He (Hemingfordian), Ba (Barstovian), Cl (Clarendonian), Hh (Hemphillian). Each point on the snake richness chart is summarized for each substage at that substage's midpoint, and is not necessarily correlated with a particular rock unit on the right.Species richness values include fossils from the entire Central Great Plains region, while localities from Nebraska specifically and discussed in this study are listed at each substage point and come from the rock units to the right. The star represents the data from this study, which updates the previous lack of data from Cl1 across North America (represented by the gray hashed line) with data from UNSM Wt-13B. NALMAs and substages are correlated with time based on data and figures from Tedford et al. (2004). Rock Units are adapted from Joeckel et al. (2017) and Tedford et al. (2004). Snake generic richness is modified and updated from Jacisin et al., 2015).
