Thylamys Minutus
''Thylamys'' is a genus of opossums in the family Didelphidae. The premaxillae are rounded rather than pointed. The females lack a pouch. The females' nipples are arranged in two symmetrical rows on the abdomen. All species but ''T. macrurus'' store fat in their tails., although this is not necessarily true for all species in the genus. Fossils belonging to the genus date back to the Miocene, with the oldest specimens being found in the Cerro Azul Formation of Argentina Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, th ... and the Honda Group of Colombia. Genetic studies indicate that the genus may have originated around 14 million years ago. Taxonomy Cladogram of living ''Thylamys'' species. Other species of ''Thylamys''.

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Thylamys Velutinus
The dwarf fat-tailed mouse opossum (''Thylamys velutinus''), also known as the velvety fat-tailed opossum is an opossum species from South America. It is endemic to Brazil, where it is found in cerrado and caatinga habitats. Its head-and-body length is about 141-212 (average 173.3) mm, and its tail length is about 73-85 (average 78) mm. Its diet is 44% arthropods; 75% of its diet consists of animals and animal products. Its ventral Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans.

Opossums
Opossums () are members of the marsupial order Didelphimorphia () endemic to the Americas. The largest order of marsupials in the Western Hemisphere, it comprises 93 species in 18 genera. Opossums originated in South America and entered North America in the Great American Interchange following the connection of North and South America. The Virginia opossum is the only species found in the United States and Canada. It is often simply referred to as an opossum, and in North America it is commonly referred to as a possum (; sometimes rendered as ''possum'' in written form to indicate the dropped "o"). Possums should not be confused with the Australasian arboreal marsupials of suborder Phalangeriformes that are also called possums because of their resemblance to the Didelphimorphia. The opossum is typically a nonaggressive animal. Etymology The word ''opossum'' is borrowed from the Powhatan language and was first recorded between 1607 and 1611 by John Smith (as ''opassom'') an ...

Thylamys Sponsorius
The Argentine fat-tailed mouse opossum (''Thylamys sponsorius'') was formerly considered a species opossum in the family Didelphidae. It is found in the eastern foothills of the Andes in northern Argentina and southern Bolivia. Its dorsal fur is gray brown to dark brown. Its ventral fur is gray-based except for the white to yellowish chest hairs. It has been distinguished from ''T. cinderella'' by its postorbital ridges. ''T. cinderella'' has well-developed postorbital ridges in both juveniles and adults that extend laterally behind the eye sockets. Only adults of ''T. sponsorius'' have fully developed postorbital ridges, and these do not extend laterally behind the eye sockets.

Thylamys Venustus
The buff-bellied fat-tailed mouse opossum (''Thylamys venustus'') is a species of opossum in the family Didelphidae. It is found in the transitional and humid forests of northern Argentina and southern Bolivia. Its dorsal fur is cinnamon brown. Most of its ventral fur is gray-based, but its chest, throat, and the thoracic midline (the midline of the thorax, which ranges from the throat to the top of the abdomen) are not gray-based. The postorbital ridges are absent in the young and weakly developed in adults. Initially classed as a Marmosa elegans subspecies, it was subsequently raised to species status in 1933. There are four synonyms: ''Marmosa elegans venusta'' (Thomas, 1902, Cochabamba), ''Marmosa elegans cinderella'' (Thomas, 1902, Tucumán Province), ''Marmosa elegans sponsoria'' (Thomas, 1921, Jujuy Province) and ''Marmosa janetta'' (Thomas, 1926, Tarija Department) with ''cinderella'' and ''sponsoria'' actually being one taxon and a subspecies of ''venustus''; ''janet ...

Thylamys Macrurus
The Paraguayan fat-tailed mouse opossum (''Thylamys macrurus'') is a species of opossum in the family Didelphidae. It is found in forested areas of Brazil and Paraguay. It is known only from a few specimens. For two listed specimens, one had a head-and-body length of about 135 mm and a tail length of about 140 mm, while the other had a head-and-body length of about 120 mm and a tail length of about 155 mm. Most of its fur is gray, but the shoulder areas are reddish gray, and the ventral fur is pure white or creamy white. There is also a ring of black fur surrounding each eye. The ventral surface of the tail is white. The dorsal surface of the tail is gray for the first one third to one half of its length (going from the base to the tip); the remainder of the dorsal surface of the tail is white. The tail is hairless except for about its first ten mm (going from the base to the tip). Although the genus Thylamys ''Thylamys'' is a genus of opossums in the family ...

Thylamys Pusillus
The common fat-tailed mouse opossum (''Thylamys pusillus'') is a species of opossum in the family Didelphidae. It occurs in Argentina, Bolivia, Brazil, and Paraguay in chaco and Andean foothill habitats. Its head-and-body length is about 75 to 120 (mean 94.3) mm, and its tail length is about 90 to 134 (mean 103.6) mm. Its dorsal fur is brownish gray, and its ventral fur is yellowish to white. The legs and cheeks are the same color as the ventral surface. Its tail is sharply bicolored (divided into two colors). A ring of faintly darker fur surrounds each eye Eyes are organs of the visual system. They provide living organisms with vision, the ability to receive and process visual detail, as well as enabling several photo response functions that are independent of vision. Eyes detect light and conv .... Its tail often lacks fat deposits, but does not always.

''Thylamys'' is a genus of opossums in the family Didelphidae. The premaxillae are rounded rather than pointed. The females lack a pouch. The females' nipples are arranged in two symmetrical rows on the abdomen. All species but ''T. macrurus'' store fat in their tails., although this is not necessarily true for all species in the genus. Fossils belonging to the genus date back to the Miocene, with the oldest specimens being found in the Cerro Azul Formation of Argentina and the Honda Group of Colombia.
