Welcome to ASM's Mammal Diversity Database

Welcome!
The Mammal Diversity Database of the American Society of Mammalogists (ASM) is your home base for tracking the latest taxonomic changes to living and recently extinct (i.e., since ~1500 CE) species and higher taxa of mammals.

Here we are curating the taxonomic implications of new research publications in real time — with the goal of promoting rigorous study of mammal biodiversity worldwide.
