Automobilid

Automobilid refers to a hypothetical group of extinct, large, herbivorous mammals that roamed during the Miocene epoch. This classification is not a recognized scientific taxon in modern paleontology but was proposed in earlier, less standardized classifications of fossil mammals. The term "Automobilid" was often used to describe a diverse assemblage of large, bulky, hoofed mammals that shared certain skeletal features, particularly in their limb structure and dentition, suggesting a herbivorous diet and a terrestrial lifestyle.

These animals are thought to have been distantly related to modern ungulates, the group that includes horses, cattle, and deer, but their exact evolutionary placement has been a subject of considerable debate. Paleontologists studying fossil finds in various parts of the world have described numerous genera and species that might have been grouped under the Automobilid umbrella. However, as the field of paleontology has advanced with more sophisticated analytical techniques, including cladistics and molecular phylogeny, the concept of broad, informal groupings like Automobilid has largely been superseded by more precise evolutionary relationships.

Current understanding suggests that the animals previously referred to as Automobilids are now classified within several distinct and well-defined mammalian orders and families, such as the Artiodactyla (even-toed ungulates) and Perissodactyla (odd-toed ungulates), as well as extinct groups whose relationships are still being refined. The term "Automobilid" is rarely used in contemporary scientific literature, though it may still appear in older texts or historical reviews of paleontology.
