Taxonomic rank is a classification level in biological taxonomy, such as species, genus, family, order, class, phylum, and kingdom.
He not only introduced the standard of class, order, genus, and species, but also made it possible to identify plants and animals from his book, by using the smaller parts of the flower (known as the Linnaean system). [51] Plant and animal taxonomists regard Linnaeus' work as the "starting point" for valid names (at 1753 and 1758 respectively ...
There are 107 classes of animals in 33 phyla in this list. However, different sources give different numbers of classes and phyla. For example, Protura, Diplura, and Collembola are often considered to be the three orders in the class Entognatha. This list should by no means be considered complete and authoritative and should be used carefully.

The classification adopted by Cuvier to define the natural structure of the animal kingdom, including both living and fossil forms, [17] was as follows, the list forming the structure of the Règne Animal. Where Cuvier's group names correspond (more or less) to modern taxa, these are named, in English if possible, in parentheses.
In their 1997 classification of mammals, McKenna and Bell used two extra levels between superorder and order: grandorder and mirorder. [5] Michael Novacek (1986) inserted them at the same position. Michael Benton (2005) inserted them between superorder and magnorder instead. [6] This position was adopted by Systema Naturae 2000 and others.
In 1997, the classification of mammals was revised by Malcolm C. McKenna and Susan K. Bell. [10] The Classification of Mammals Above the species level, here referred to as the "McKenna/Bell classification", is a comprehensive work on the systematics, relationships, and occurrences of all mammal taxa, living and extinct, down through the rank of ...
