Word Nuance & Usage

Although frequently confused with the mammoth, the mastodon was a distinctly different animal; it was generally shorter, inhabited woodlands rather than open steppes, and possessed uniquely shaped molar teeth adapted for browsing on trees and shrubs rather than grazing on grass.

Word Origin & Etymology

Coined in the early 19th century by French anatomist Georges Cuvier from modern Latin. It derives from the Greek words 'mastos' (breast) and 'odous' or 'odont-' (tooth), referencing the distinctive, nipple-like projections on the crowns of the animal's molar teeth.
