ABSTRACT
The larger mammals have been studied for a long time and the Pleistocene record of many of them is tolerably well established. Some of the illustrations represent attempts to portray extinct animals in the flesh. The restorations are usually based on complete skeletons, so that the relative proportions of head, neck, body, and limbs should generally be correct. The skeletal anatomy also gives information on the characteristic poise of the animal. A species name consists of two parts. The first part, in which the initial letter is capitalized, is also the name of the genus to which the species belongs. The second part, which should never be written with a capitalized initial letter, is termed the trivial name. Subspecies are formally recognized subdivisions of species, representing temporal and/or local populations that are more or less clearly distinguishable morphologically from other populations of the same species.
