The ring-tailed lemur was one of the first lemurs to be classified, by Carl Linnaeus in 1758.. Lemurs were first classified in 1758 by Carl Linnaeus, and the taxonomy remains controversial today, with approximately 70 to 100 species and subspecies recognized, depending on how the term "species" is defined.
The ringtail is commonly found in rocky desert habitats, where it nests in the hollows of trees or abandoned wooden structures. It has been found throughout the Great Basin Desert , which stretches over several states (Nevada, Utah, California, Idaho, and Oregon) as well as the Sonoran Desert in Arizona, and the Chihuahuan Desert in New Mexico ...
There are two extant species in the genus: the ringtail or ring-tailed cat (B. astutus) and the cacomistle (B. sumichrasti). Genetic studies have indicated that the closest relatives of Bassariscus are raccoons, [2] [3] [4] from which they diverged about 10 million years ago in the Tortonian Age of the Miocene. [4]
Procyonid fossils once believed to belong to the genus Bassariscus, which includes the modern ringtail and cacomistle, have been identified from the Miocene epoch, around 20 million years ago. It has been suggested that early procyonids were an offshoot of the canids that adapted to a more omnivorous diet. [ 13 ]
In biology, taxonomic rank (which some authors prefer to call nomenclatural rank [1] because ranking is part of nomenclature rather than taxonomy proper, according to some definitions of these terms) is the relative or absolute level of a group of organisms (a taxon) in a hierarchy that reflects evolutionary relationships.

In botany, the ranks of subclass and suborder are secondary ranks pre-defined as respectively above and below the rank of order. [7] Any number of further ranks can be used as long as they are clearly defined. [7] The superorder rank is commonly used, with the ending -anae that was initiated by Armen Takhtajan's publications from 1966 onwards. [8]
The ring-tailed lemur (Lemur catta) is a medium- to larger-sized strepsirrhine (wet-nosed) primate and the most internationally recognized lemur species, owing to its long, black-and-white, ringed tail.
