İndomustelomimus procenozoica ("the first Cenozoic Indian Weasel-Mimic") was a medium-sized Eutricinodont mammal that appeared 65-59 Ma when India was still an island, itself probably evolved from a small burrowing Eutricinodont species, and that suspected genus survived the mass extinction that wiped out all non-avian dinosaurs 66 Ma ago, and was later the ancestor of Indomustelomimus.

Indomustelomimus was a medium-sized land predator, its diet included small vertebrates such as Nasicabatrachids, Caecilians, Centipedes and Lesser Gondwanatherians, and was a diurnal animal, usually emerging during the day and sleeping at night.  It is estimated that during the mating season, male individuals would beat each other and claw their heads because there are protrusions in some fossils, but this is not natural, it is thought to be from another animal, if examined, it is noticed that this was done by another indomustelomimus.

However, it also became extinct, but continued its legacy for a very long time and caused the emergence of Carnomammians, but when India became a subcontinent of Asia, it was a disaster because it almost managed ecosystems they had never known, but Orientalia, which was a lifeboat, was a shelter for various non-therian mammals such as Carnomammians, Gondwanatherians and is still considered so today, but on the mainland, a group of Carnomammians continued to compete with other predatory mammals and they were called Goldcats
