Argentoconodon modernus (meaning "Argentina cone tooth of modern times") is a species of flying theriimorph mammal that originally lived in the Cañadón Asfalto Formation of the Cañadón Asfalto Basin in Patagonia during the Early Jurassic. It was once extinct, but has since been brought back from extinction by SciiFii. It was originally planned to be included for Cretaceous Park, located in Sacromento, California, but an accident occurred where SciiFii's workers forgot to close the transport cages for the Mesozoic flying mammals, letting them fly out and escape into the wilderness. Ever since the accident, decades later, the populations of Argentoconodon modernus in the western United States and Mexico have increased from just 11 pairs to more than 4 million, thanks to their prolific nature and being adaptable, surviving in a wide range of natural environments and human settlements. It is known for its molariform teeth, which possesses a combination of primitive and derived features. It is a carnivore that prefers to feed on insects, spiders, scorpions, frogs, lizards, and smaller mammals. It is densely covered by fur to keep it insulated from the cold of night. The tail is flat, increasing the airfoil, and the limbs are proportionally long, comparable to those of modern flying and gliding mammals. The toes are grasping, as typical for arboreal mammals. It is a much more efficient glider than the Asian colugo due to its wing size and other adaptations, but is a poor flyer due to its shorter wing size compared with bats, and has weak arm muscles, preferring to glide over flying. Argentoconodon modernus is similar to the related Ichthyoconodon, Jugulator, Volaticotherium, and Triconolestes.
