Crocodylian princess in Taiwan: Revising the taxonomic status of Tomistoma taiwanicus from the Pleistocene of Taiwan and its paleobiogeographic implications
<p><em>Toyotamaphimeia</em>, deriving from a mythological princess in Japan into a crocodile, refers to an extinct crocodylian lineage. Here, we reexamine the holotype of a long-forgotten species: <em>Tomistoma taiwanicus </em>from the Pleistocene of Tainan (Taiwan) and revise its taxonomic status to <em>Toyotamaphimeia taiwanicus </em>comb. nov., leading to the first recognized species of <em>Toyotamaphimeia </em>outside Japan. Our phylogenetic analyses also support this taxonomic assignment and, more interestingly, further suggest an East Asian lineage. In addition, <em>Toyotamaphimeia taiwanicus</em> represents a tropical species, resolving a long-lasting puzzle of why <em>Toyotamaphimeia </em>only inhabited the much higher latitudinal area (Japan). Given the large body size of <em>Toyotamaphimeia taiwanicus</em> (about 7 m) and geologically older than <em>Toyotamaphimeia machikanensis</em> from Japan, we propose a novel evolutionary scenario: the genus <em>Toyotamaphimeia </em>originated in Taiwan and evolved to a large body size with gigantothermic physiology, allowed an Out-of-Taiwan scheme, and dispersed further north to Japan. Our taxonomic identification shows the presence of an extinct endemic crocodylian species from the Pleistocene of Taiwan with large-scale paleogeographic implications, and this study, with our recent progress in vertebrate paleontology in Taiwan, should provoke more in-depth paleontological research on elucidating a larger picture of the Pleistocene extinction.</p>
