shoulder, compared with about 2 m for the largest modern camelids. Other extinct camelids included small, gazelle-like animals, such as Stenomylus. Finally, a number of very tall, giraffe-like camelids were adapted to feeding on leaves from high trees, including such genera as Aepycamelus and Oxydactylus. Whether the wild Bactrian camel (Camelus ferus) is in fact a distinct species or a subspecies (Camelus bactrianus ferus) is still debated. The divergence date is 0.7 million years ago, long before the start of domestication.
