Platacanthomyinae
The rodent family Platacanthomyidae, or Oriental dormice, includes the spiny dormice and the Chinese pygmy dormice. In spite of their appearance, these animals are not true dormice, but are part of the large and complex superfamily Muroidea. The platacanthomyids can be distinguished from the true dormice, because they have no premolars, giving them three cheek teeth, like their relatives, the Muroidea. The evolutionary relationship of the Platacanthomyidae was uncertain until a molecular phylogenetic study found it to be the earliest extant lineage to branch within the superfamily Muroidea. They can be distinguished from both the family Spalacidae and the Eumuroida (all non-spalacid and non-platacanthomyid muroids), by the distinct shape of their infraorbital canal and by the presence of multiple openings in the palate of the skull. On the basis of these two characteristics, they have been considered to be distinct from all other muroids. More work is needed to determine ...

Malabar Spiny Dormouse
The Malabar spiny dormouse (''Platacanthomys lasiurus'') is a species of muroid rodent endemic to the Western Ghats of India. It is the only extant species in the genus ''Platacanthomys'' and although resembling a dormouse, it is not closely related. About the size of a brown rat, this arboreal species lives in tree holes in dense forest habitats in a small family group. They are distinguishable from other species in the area by their bushy tuft tip to the tail and the spiny fur on the back. Description This rodent is about 5 in long with a 4-in tail. The ears are large and pointed at the tip. The whiskers are numerous and some are very long. The hairy tail is covered with longer hairs towards the end, making the tail wider at the tip. The hairs arise on the sides towards the base of the tail (an arrangement termed as "subdistichous") giving the tail a slightly flattened appearance. The pollux ("thumb") and hallux ("big toe") are without claws. The skull is broad and flat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Muroid Rodents
The Muroidea are a large superfamily of rodents, including mice, rats, voles, hamsters, lemmings, gerbils, and many other relatives. Although the Muroidea originated in Eurasia, they occupy a vast variety of habitats on every continent except Antarctica. Some authorities have placed all members of this group into a single family, Muridae, due to difficulties in determining how the subfamilies are related to one another. Many of the families within the Muroidea superfamily have more variations between the families than between the different clades. A possible explanation for the variations in rodents is because of the location of these rodents; these changes could have been due to radiation or the overall environment they migrated to or originated in. The following taxonomy is based on recent well-supported molecular phylogenies. The muroids are classified in six families, 19 subfamilies, around 280 genera, and at least 1,750 species.
