Mastodon have been no reports of currently recognized "Mammut" species outside of North America according to Paleobiology database (which does not recognize "M. borsoni"). However, the status of "Mammut" or "Zygolophodon borsoni" in the literature appears equivocal. "Mammut" is a genus of the extinct family Mammutidae, related to the proboscidean family Elephantidae (mammoths and elephants), from which it originally diverged approximately 27 million years ago. The following cladogram shows the placement of the American mastodon among other proboscideans, based on hyoid characteristics: Over the years, several fossils from localities in North America, Africa and Asia have been attributed to "Mammut", but
Ancient Beringian Ancient Beringian The Ancient Beringians (AB) is the name given to a specific archaeogenetic lineage, based on the genome of an infant found at the Upward Sun River site (dubbed USR1), dated to 11,500 years ago. The AB lineage diverged from the Ancestral Native American (ANA) lineage about 20,000 years ago. The ANA lineage was estimated as having been formed between 20,000 and 25,000 years ago by a mixture of Proto-Mongoloid and Ancient North Eurasian lineages, consistent with the model of the peopling of the Americas via Beringia during the Last Glacial Maximum. The Ancient Beringian lineage is extinct, and
