Indotriconodon magnus is an extinct mammal from the Late Cretaceous of India. An eutriconodont, it represents the geologically youngest of the group dating to the Maastrichtian just a few thousand years before the KT event (a reccord previously held by Alticonodon lindoei from the Campanian of Canada), as well as a relatively large sized Mesozoic mammal.^[1]

Description

Indotriconodon magnus is known only from a single lower molar. It is about 20% smaller than that of Repenomamus giganticus but larger than that of other eutriconodonts, making it a badger-sized mammal.^[1]

Phylogeny

In its 2024 description it nests deeply within Eutriconodonta, being sister taxa to Volaticotherini.^[1]

Palaeoceology

Found in the Intertrappean Beds, it co-existed with at least other ten mammal genera as well various squamates, turtles and dinosaurs.^[1] In this time, India was isolated from other landmasses, and had a unique island biota.
