Abstract The Fayum Depression of Egypt has yielded fossils of hystricognathous rodents
from multiple Eocene and Oligocene horizons that range in age from∼ 37 to∼ 30 Ma and …

The fossil record of phiomorph hystricognathous rodents from the Afro-Arabian Paleogene is
important for understanding the origins and dispersal routes of the early crown …

Early hystricognathous rodents from Africa are primarily documented by two basal and
extinct groups, the paraphyletic “Phiomyidae” and the Gaudeamuridae, which were …

Background Gaudeamus is an enigmatic hystricognathous rodent that was, until recently,
