       Kimbetopsalis is a genus of multituberculatan mammal that lived in the USA not long after the asteroid impact that marked the KT extinction that ended the reign of the dinosaurs.‭ ‬Kimbetopsalis has been identified as a member of the Multituberculata due to the large number‭ ‬of cusps that are clearly visible upon the teeth of the holotype,‭ ‬which are partial skull,‭ ‬including upper jaw bone and teeth.‭ ‬Mammals similar to Kimbetopsalis are known from earlier in the Cretaceous period,‭ ‬but these were mostly small,‭ ‬rarely no bigger than modern day rats‭ (‬though there were a few exceptions‭)‬.‭ ‬With a roughly estimated size of just under a meter,‭ ‬Kimbetopsalis was significantly larger than these,‭ ‬and may have grown so large because at the time it lived there may have been an absence of large predatory animals,‭ ‬with‭ ‬the worlds ecosystems still recovering from the KT extinction.
