Short summary
Mennerotodus is a genus of fossil shark that lived during the Paleogene Period, between 65 and 38 million years ago, and was previously known only from Asia and Europe. In this study, new species of Mennerotodus have been identified in the USA from Alabama (Mennerotodus mackayi) and South Carolina (Mennerotodus parmleyi). Mennerotodus mackayi is the oldest of the species, suggesting the genus originated in the Gulf Coastal Plain of the USA during the Paleocene Epoch (~ 65 million years ago).
