Eomys is an extinct genus of eomyid rodent from the late Oligocene of France, Germany, Spain, and possibly Turkey. The species Eomys quercyi is the earliest known gliding rodent. [1] [2]

Cimolodonta is a clade of multituberculate mammals that lived from the Cretaceous to the Eocene. They probably lived something of a rodent-like existence until their ecological niche was assumed by true rodents. The more basal multituberculates are found in a different suborder, "Plagiaulacida", a paraphyletic group containing all non cimolodontan multituberculates.
Hainina is an extinct mammal genus from the latest Cretaceous to the Paleocene of Europe.
The family Aplodontiidae also known as Aplodontidae, Haplodontiidae or Haploodontini is traditionally classified as the sole extant family of the suborder Protrogomorpha. It may be the sister family of the Sciuridae. There are fossils from the Oligocene until Miocene in Asia, from Oligocene in Europe and from the Oligocene until the present in North America, where there is the only living species: the mountain beaver.
Caviomorpha is the rodent parvorder that unites all New World hystricognaths. It is supported by both fossil and molecular evidence. The Caviomorpha was for a time considered to be a separate order outside the Rodentia, but is now accepted as a genuine part of the rodents. Caviomorphs include the extinct Heptaxodontidae, the extinct Josephoartigasia monesi and extant families of chinchilla rats, hutias, guinea pigs and the capybara, chinchillas and viscachas, tuco-tucos, agoutis, pacas, pacaranas, spiny rats, New World porcupines, coypu and octodonts.
Sciurognathi is a suborder of rodents that includes squirrels, chipmunks, beavers, and many types of mice. The group is characterized by a specific shape to the lower jaw. In sciurognaths, the angular process of the jaw is in the same plane as the root of the incisors. This is in contrast to the suborder Hystricognathi where the angular process is outside the plane formed at the root of the incisor due to the presence of a shelf for muscle attachment.
Hystricomorpha is a term referring to families and orders of rodents which has had many definitions throughout its history. In the broadest sense, it refers to any rodent with a hystricomorphous zygomasseteric system. This includes the Hystricognathi, Ctenodactylidae, Anomaluridae, and Pedetidae. Molecular and morphological results suggest the inclusion of the Anomaluridae and Pedetidae in Hystricomorpha may be suspect. Based on Carleton & Musser 2005, these two families are discussed here as representing a distinct suborder Anomaluromorpha.
Pseudoltinomys is a prehistoric rodent that lived approximately 30 million years ago, during the Oligocene epoch. It outwardly resembles a gerbil, but may have been related to kangaroo rats or may represent an early offshoot of rodents with no modern relatives.
Diatomyidae is a family of hystricomorph rodents. It is represented by a single living species, Laonastes aenigmamus, native to Laos in Southeast Asia. Fossil species are known from the Oligocene and Miocene of Asia and eastern Europe.
Eomyidae is a family of extinct rodents from North America and Eurasia related to modern day pocket gophers and kangaroo rats. They are known from the Middle Eocene to the Late Miocene in North America and from the Late Eocene to the Pleistocene in Eurasia. Eomyids were generally small, but occasionally large, and tended to be squirrel-like in form and habits. The family includes the earliest known gliding rodent, Eomys quercyi.
The Cameroon scaly-tail, also referred to as the Cameroon anomalure, flightless anomalure or flightless scaly-tail, is a rodent species endemic to West Central Africa. The scientific literature has never reported observations of live individuals. The taxonomic classification of the species has been subject to recent revision.
Enspel is an Ortsgemeinde – a community belonging to a Verbandsgemeinde – in the Westerwaldkreis in Rhineland-Palatinate, Germany.
Zenkerella is a genus of rodent, the only member of the family Zenkerellidae. It was formerly classified in Anomaluridae until phylogenetic studies made its distinctiveness clear. While the Anomalurus of the family Anomaluridae has gliding membranes between its forelimb and hindlimb, the Zenkerella has no such adaptation. It is estimated from fossil records that this divergence might have occurred in the middle of the Eocene.
Masillamys is an extinct genus of rodent. It was named in 1954 by Tobien based on fossils found in the Quercy Phosphorites Formation, France. It is considered to be a sister genus to the Hartenbergeromys, Lophiparamys, Mattimys, Microparamys, Pantrogna, Sparnacomys, and Strathcona genera.

The Conglomérat de Cernay is a geologic formation in Champagne-Ardenne, northern France. It preserves fossils dating back to the Thanetian stage of the Paleocene period. The lizard Cernaycerta and placental mammal Bustylus cernaysi are named after the formation.
The Quercy Phosphorites Formation is a geologic formation and lagerstätte in Occitanie, southern France. It preserves fossils dated to the Paleogene period, or MP16 to MP28 zones of the European land mammal age classification, ranging from approximately 38 to 25 Ma.
Auroremys is an extinct genus of Palaeogene rodents belonging to the theridomorph family Pseudosciuridae. The type and only species Auroremys subita was first named by Bernard Comte et al. in 2012 as belonging to the ischyromyid genus Ailuravus before it was eventually reclassified to its own genus by French palaeontologists Monique Vianey-Liaud and Laurent Marivaux in 2021.
Burgia is an extinct genus of Palaeogene rodents belonging to the family Theridomyidae. It is more specifically classified to the subfamily Patriotheridomyinae and contains one species Burgia marandati. The type and only species was originally classified to another genus name Bernardia by Monique Vianey-Liaud in 1991 before the genus name usage was rendered invalid due to it being preoccupied by a scale insect in 1891. Burgia marandati is known from a holotype consisting of a lower molar from the French locality of Lavergne that dates to the middle Eocene. The genus is named after the Bach mayor Pierre Burg, who assisted palaeontologists in their research locally.
Idicia is an extinct genus of Palaeogene rodents belonging to the family Theridomyidae. The genus and its sole species Idicia vidalenci were both named by Monique Vianey-Liaud et al. in 2024 based on some holotype dentition from the French locality of Lavergne, dating to the middle Eocene. It was named in honor of Dominique Vidalenc, who discovered the holotype material. It is diagnosed as being a medium-sized and brachyodont (low-crowned) theridomyid with various specific morphologies of its cuspids. A wide range of other faunas were recovered form Lavergne along with Idicia such as the herpetotheriid Peratherium, nyctithere Saturninia, omomyid Necrolemur, carnivoraforme Quercygale, tapirulid Tapirulus, and the palaeothere Palaeotherium.
