Tseng: Ancient Otter Tooth Found in Mexico Suggests Mammals Migrated Across America

Updated June 30, 2017 This content is archived.

Research by Jack Tseng, PhD, assistant professor of pathology and anatomical sciences, suggests that otters may have migrated across America about 6 million years ago along the northern edge of the Trans-Mexican Volcanic Belt, which runs across Mexico. “This is an entirely new idea that no one else has proposed,” he said. “We think it’s very likely other animals utilized this route.”
