This checklist of mammal orders and families is derived from several sources. In some cases, there is disagreement among the experts on the exact number of species. In cases like this, I have put the alternative values together separated by a slash (as in the Didelphidae below).
However, it should be noted I do not have access to the most up-to-date data and this list should be considered to be about 10 years old.

- *0 In many books the Great Apes are included in a separate family, the Pongidae, however while there are strong social reasons for separating them the scientific reasons are doubtful.
- *1 The Xenarthra are known as the Edentata in some books.
- *2 The Spalacidae are often included in the Muridae as the subfamily Spalacinae.
- *3 The Myocastoridae are sometimes included in the Capromyidae.
- *4 The Capromyidae is an interesting family because it contains an additional 4 genera and 18 species which have gone extinct in geologically recent times.
- *5 This includes Dusicyon australis which is considered to have gone extinct in 1870.
- *6 Note that Stellar’s Sea Cow, Hydrodamalis gigas, is believed to have become extinct around 1768.
I would like to thank Professor Brad Bergstrom, Dept. of Biology, Valdosta St. Univ. for looking over this list and for the corrections and suggestions regarding the mammal orders and families that he made.
I’m wondering why this table isn’t arranged alphabetically by order. It would be more useful to me and others I should think.
The arrangement of the orders pretty much follows George Gaylord Simpson’s classic “Principles of Classification and a Classification of Mammals” (Simpson, 1945) which was the basic textbook system up until the end of the last century. The apparent alphabetic disorganization is created by un-included (for simplification) of higher levels of classification that represent degrees of relatedness, such as infraclass and subclass which link various orders together. That said this table is now well out of date and I will put updating it on the top of my to do list.
