Altmuehlopterus is a genus of pterosaur belonging to the Pterodactyloidea. It lived in the Late Jurassic of what is now Germany. It was formerly known as "Daitingopterus", a nomen nudum, informally coined in 2004.

The Asian garden dormouse or large-eared garden dormouse, is a species of rodent in the family Gliridae. It is found in Egypt, Iraq, Israel, Jordan, Lebanon, Libya, Saudi Arabia, Syria and Turkey. Its natural habitats are temperate forests, subtropical or tropical dry shrubland, Mediterranean-type shrubby vegetation, rocky areas and gardens. It is active throughout the year but can enter a state of torpor. Diet consists mainly of insects, snails, centipedes and geckos but as an omnivore, it will also eat plant matter. It is a common species and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".

The big naked-backed bat, is a bat species from South and Central America.

The marsh deer is the largest deer species from South America reaching a length of 2 m (6.6 ft) and a shoulder height of 1.2 m (3.9 ft). It is found in Argentina, Bolivia, Peru, Brazil, Uruguay and Paraguay. Formerly found in much of tropical and subtropical South America, it ranged east of the Andes, south from the Amazon rainforest, west of the Brazilian Atlantic rainforest and north of the Argentinian Pampa. Today it is largely reduced to isolated populations at marsh and lagoon zones in the Paraná, Paraguay, Araguaia and Guapore river basins. Small populations also occur in the southern Amazon, including Peru where protected in Bahuaja-Sonene National Park. It is listed as a vulnerable species by the IUCN and on CITES Appendix I.

Compsognathus is a genus of small, bipedal, carnivorous theropod dinosaur. Members of its single species Compsognathus longipes could grow to around the size of a turkey. They lived about 150 million years ago, during the Tithonian age of the late Jurassic period, in what is now Europe. Paleontologists have found two well-preserved fossils, one in Germany in the 1850s and the second in France more than a century later. Today, C. longipes is the only recognized species, although the larger specimen discovered in France in the 1970s was once thought to belong to a separate species and named C. corallestris.

Dorygnathus was a genus of pterosaur that lived in Europe during the Early Jurassic period, 180 million years ago when shallow seas flooded much of the continent. It had a short 1.5 meters wingspan, and a relatively small triangular sternum, which is where its flight muscles attached. Its skull was long and its eye sockets were the largest opening therein. Large curved fangs that "intermeshed" when the jaws closed featured prominently at the front of the snout while smaller, straighter teeth lined the back. Having variable teeth, a condition called heterodonty, is rare in modern reptiles but more common in primitive pterosaurs. The heterodont dentition in Dorygnathus is consistent with a piscivorous (fish-eating) diet. The fifth digit on the hindlimbs of Dorygnathus was unusually long and oriented to the side. Its function is not certain, but the toe may have supported a membrane like those supported by its wing-fingers and pteroids. Dorygnathus was according to David Unwin related to the Late Jurassic pterosaur, Rhamphorhynchus and was a contemporary of Campylognathoides in Holzmaden and Ohmden.

Peromyscus maniculatus is a rodent native to eastern North America. It is most commonly called the eastern deer mouse; when formerly grouped with the western deer mouse, it was referred to as the North American deermouse and is fairly widespread across most of North America east of the Mississippi River, with the major exception being the lowland southeastern United States.

Eliomys is a genus of rodent in the family Gliridae.

Eurycormus is an extinct genus of prehistoric bony fish that lived from the Callovian stage of the Middle Jurassic epoch to the early Tithonian stage of the Late Jurassic epoch.

Euryoryzomys russatus, also known as the russet oryzomys, russet rice rat, or big-headed rice rat, is a species of rodent in the family Cricetidae. It is a member of the genus Euryoryzomys, which was split off from Oryzomys in 2006. It was first described by Johann Andreas Wagner in 1848. It is found in southern Brazil, eastern Paraguay and northeastern Argentina. It is considered a large species in its genus, with a reddish-brown coat, long tail length, and large skull. It is a terrestrial rodent, spending its time foraging for seeds, fruits, and insects. It is listed by the IUCN as least concern, although studies have shown it to be influenced by anthropogenic disturbances. Predators consist of small members of the order Carnivora.

The giant roundleaf bat is a species of bat in the family Hipposideridae found in western tropical Africa. Its natural habitats are subtropical or tropical moist lowland forests and caves. The species was formerly considered part of M. commersoni, which is now viewed as being restricted to Madagascar. Both commersoni and it were formerly placed in the genus Hipposideros, but moved to the resurrected Macronycteris in 2017 on the basis of molecular evidence. It is threatened by habitat loss.

Gracilinanus is a genus of opossum in the family Didelphidae. It was separated from the genus Marmosa in 1989, and has since had the genera Cryptonanus, Chacodelphys, and Hyladelphys removed from it.

The Ipanema bat is a bat species of order Chiroptera and family Phyllostomidae. It is found in South America, specifically in northern Argentina, Bolivia, southeastern Brazil and Paraguay. It is monotypic within its genus.

Mesomys is a genus of South American spiny rats in the family Echimyidae.

The northern treeshrew is a treeshrew species native to Southeast Asia.

Oecomys concolor, also known as the unicolored oecomys, unicolored rice rat, or unicolored arboreal rice rat, is a species of rodent in the genus Oecomys of family Cricetidae. It is found in tropical rainforest in the Amazon biome, but its range is poorly documented; it has been recorded in northwestern Brazil, southeastern Colombia, and southern Venezuela.

The pale spear-nosed bat (Phyllostomus discolor) is a species of phyllostomid bat from South and Central America.

Paracestracion is an extinct genus of heterodontid sharks from Early Jurassic to Early Cretaceous-aged rocks of England, France, Germany and Luxembourg. The genus, first described in 1911 by Ernst Hermann Friedrich von Koken in Karl Alfred von Zittel, contains five species: P. bellis from the Bathonian of England, the type species P. falcifer from the Tithonian and Kimmeridgian of Weymouth, England and Solnhofen, Germany, which was originally named as a species of Cestracion in 1857 by Johann Andreas Wagner, P. pectinatus from the Valanginian of France, P. sarstedtensis, originally classified as a species of Heterodontus, from the Toarcian and Aalenian of Germany, and P. viohli from the Tithonian-aged Painten Formation of Germany, with a sixth indeterminate species known from the Toarcian-aged Variabilis layer of the La Couche à Crassum of Luxembourg.

The Paraguayan punaré, Thrichomys pachyurus, is a caviomorph rodent of South America from the spiny rat family. With its skull averaging 55 mm long, it is the largest species in the genus Thrichomys. It is found in savannas and forest edges in southwestern Brazil and northern Paraguay within the cerrado ecoregion. The species tolerates a degree of habitat disturbance, and is considered abundant throughout its range.

The great gerbil is a large rodent found throughout much of Central Asia.

The saddle-back tamarins are squirrel-sized New World monkeys from the family Callitrichidae in the genus or subgenus Leontocebus. They were split from the tamarin genus Saguinus based on genetic data and on the fact that saddle-back tamarins are sympatric with members of Saguinus to a greater extent than would be expected from two members of the same genus. Some authors still consider Leontocebus to be a subgenus of Saguinus.

The treeshrews are small mammals native to the tropical forests of South and Southeast Asia. They make up the entire order Scandentia, which split into two families: the Tupaiidae, and the Ptilocercidae.

Scaphognathus was a pterosaur that lived around Germany during the Late Jurassic. It had a wingspan of 0.9 m (3 ft).

The rodent subfamily Sigmodontinae includes New World rats and mice, with at least 376 species. Many authorities include the Neotominae and Tylomyinae as part of a larger definition of Sigmodontinae. When those genera are included, the species count numbers at least 508. Their distribution includes much of the New World, but the genera are predominantly South American, such as brucies. They invaded South America from Central America as part of the Great American Interchange near the end of the Miocene, about 5 million years ago. Sigmodontines proceeded to diversify explosively in the formerly isolated continent. They inhabit many of the same ecological niches that the Murinae occupy in the Old World.

A cotton rat is any member of the rodent genus Sigmodon. Their name derives from their damaging effects on cotton as well as other plantation crops, such as sugarcane, corn, peanut and rice. Cotton rats have small ears and dark coats, and are found in North and South America. Members of this genus are distributed in the Southwestern United States, Mexico, Central America, and South American countries of: Venezuela, Ecuador, Colombia, Peru, Brazil, Guyana, and Suriname. Many of the species are found in Mexico.

Simocyon is a genus of extinct carnivoran mammal in the family Ailuridae. Simocyon, which was about the size of a mountain lion, lived in the late Miocene and early Pliocene epochs, and has been found in Europe, Asia, and rarely, North America and Africa.

Taurotragus is a genus of large antelopes of the African savanna, commonly known as elands. It contains two species: the common eland T. oryx and the giant eland T. derbianus.

The Tehuantepec jackrabbit is a jackrabbit endemic to Mexico.

Wagner's mustached bat is a bat species from South and Central America. It is one of the few New World bats species known to perform Doppler shift compensation behavior.

The western deermouse or western deer mouse is a rodent native to North America. It is widespread throughout the western half of the continent, mainly in areas west of the Mississippi River.

Xenopus is a genus of highly aquatic frogs native to sub-Saharan Africa. Twenty species are currently described within it. The two best-known species of this genus are Xenopus laevis and Xenopus tropicalis, which are commonly studied as model organisms for developmental biology, cell biology, toxicology, neuroscience and for modelling human disease and birth defects.
