FIGURE 7 in Oldest record of Alligator in southeastern North America
FIGURE 7. Box and whisker plots of dorsal skull length of published fossil Alligator specimens and extant Alligator mississippiensis (this study). For data, see Table 3. Time shown in millions of years ago (MYA). UF 422816, an isolated right premaxilla, was estimated following methods outlined in the main document. Most notable is that the estimated dorsal skull length for UF 422816 is small, similar to ancestral forms such as Allognathosuchus, Procaimanoidea, and Wannaganosuchus.
