Allocamelus from Edward Topsell's
The History of Four-footed Beasts and Serpents, 1658; the image was originally from a Dutch work published in 1558. Topsell believed that the creature was the offspring of a camel and mule.
In heraldry, the allocamelus, or ass-camel, was the depiction of a mythical creature with the head of a donkey and body of a camel; it is the legendary representation of the llama.
