cimolodontids
Cimolodontids were a family of multituberculate mammals that lived during the Late Cretaceous and Paleocene epochs. Multituberculates were a successful and diverse group of early mammals, distinguished by their unique dental adaptations, particularly a large, serrated lower premolar. Cimolodontids are considered among the most derived of the multituberculates.
Fossils of cimolodontids have been found primarily in North America and Europe. They are known from skeletal
The evolutionary history of cimolodontids places them within the order Multituberculata, a lineage that persisted for
