Huarizo
According to the University of Minnesota, it may not have been fully infertile when it was naturally stored. Huarizo is related to alpacas because it is a cross between a male llama and a female alpaca. Because of their appearance and size, the species was also known as the South American camelids. Huarizo was around the size of a llama. According to the University of Minnesota Rochester, the creature was also regarded as sterile, but it could be preserved with a minimal genetic alteration.
