Eutriconodonta

Eutriconodonta
Temporal range: Early Jurassic - Late Cretaceous, 184–66 Ma
Examples of several eutriconodonts. Clockwise: Repenomamus, Volaticotherium, Jeholodens and Yanoconodon. These occupy vastly different ecological niches: bulky semi-fossorial carnivore, glider, arboreal insectivore and terrestrial carnivore, respectively.[1]

Subgroups

Eutriconodonta is an order of early mammals. Eutriconodonts existed in Asia (including pre-contact India), Africa, Europe, North and South America during the Jurassic and the Cretaceous periods. The order was named by Kermack et al. in 1973[2] as a replacement name for the paraphyletic Triconodonta.[3]

Traditionally seen as the classical Mesozoic small mammalian insectivores, discoveries over the years have shown them to be among the best examples of the diversity of mammals in this time period, including a vast variety of bodyplans, ecological niches and locomotion methods.[4][5][6][1][7][8]
