Koelain

Koelain is a genus of extinct mammals that lived during the Paleocene epoch, approximately 66 to 56 million years ago. These early mammals are known from fossil remains found primarily in North America. Koelain is classified within the order Multituberculata, a diverse and successful group of mammals that existed for over 100 million years. Multituberculates are characterized by their distinctive dentition, particularly the presence of large, specialized incisors and a series of molariform teeth.

The genus Koelain itself is notable for its relatively small size. Fossil evidence suggests that Koelain species were likely herbivorous or possibly omnivorous, feeding on plants, seeds, and possibly insects. Their skeletal structure indicates they were likely terrestrial animals, possibly adapted for burrowing or living in forested environments. The exact phylogenetic relationships of Koelain within the Multituberculata are still debated among paleontologists, but it is generally placed within the suborder Cimolodonta. The discovery of Koelain fossils contributes to our understanding of the early diversification of mammals following the extinction of the non-avian dinosaurs.
