Triconodontidae is an extinct family of actively mobile mammal, endemic to what would be North America, Europe, Africa and probably also South America and Asia^[1][2] during the Jurassic through Cretaceous periods at least from 155.7—70.6 mya (however, if Argentoconodon is indeed a member of the family then it existed as early as Middle, possibly even Early Jurassic^[1]), existing for at least 85.1 million years.^[3]

Taxonomy

Triconodontidae was named by Marsh (1887). It was assigned to Polyprotodontia by Cope (1889); to Triconodonta by Rasmussen and Callison (1981), Bonaparte (1986), Carroll (1988) and Engelmann and Callison (1998); and to Mammalia by Marsh (1887) and Luo et al. (2001).^[4]
