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 ...
Ringtail: Southern United States from southern Oregon and California throughout the southwestern states to Texas. In Mexico it ranges from the northern desert state of Baja California to Oaxaca. Its distribution overlaps that of B. sumichrasti in the Mexican states of Guerrero, Oaxaca and Veracruz. [9] † Bassariscus casei [10] Case's ringtail ...
The relationship between the aye-aye and the rest of the lemurs has had the greatest impact on lemur taxonomy at the family rank and above. Genetic analysis of this relationship has also clarified lemur phylogeny and supports the hypothesis that lemurs rafted to Madagascar. Despite general agreement on phylogeny, the taxonomy is still under debate.
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.
The hierarchy of biological classification's eight major taxonomic ranks. A domain contains one or more kingdoms. Intermediate minor rankings are not shown. In biology, a kingdom is the second highest taxonomic rank, just below domain. Kingdoms are divided into smaller groups called phyla (singular phylum).
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.
Pseudocheirus is a genus of ringtail possums (family Pseudocheiridae). It includes a single living species, the common ringtail possum (Pseudocheirus peregrinus) of Australia, as well as the fossil Pseudocheirus marshalli from the Pliocene of Victoria. [1] Other species have previously been included in this genus.
