While there was a large amount of faunal specimens, only a small portion could be used for further research due to poor preservation. Most of the indicated remains are fragments of bones of varying sizes. Tank 1 had better preserved remnants than Tank 2 did. Of the identified specimens, most were only categorized as far as their size or
taxa. Forty nine taxa were found in the faunal remains, with the most numerous being small fish and medium sized mammals. Analysis of the present remains indicates that mammals were killed elsewhere, and smaller ones were brought back whole while only parts of larger mammals were carried to the rock tanks. Dating shows that Rock Tank 1 experienced one period of use, while Tank 2 was used during three distinct periods. All of the animals represented by the faunal remains at Ratho Krankoop were linked symbolically to rain across
Africa and many appear frequently in rock art.
Mammals Rhinoceros, found in faunal remains and artistic representation, are considered in surrounding cultures to be very potent, making them symbols of power and the elite. Kudu, klipspringers, and cattle have more direct associations with water through rain rituals. People in Botswana hunt kudu during times of drought and then grind the dung in their stomachs to a powder. Klipspringers are also hunted during dry seasons. People wash them with rain medicine before killing them and burning their bones. The imagery of blackened bones is said to form dark rain clouds. As for cattle, a cow's stomach placed on a grave is believed to bring rain in some cultures. Of these three bovids, the archaeological remains consist mainly of bone fragments from facial features, teeth, and limbs. Lastly,
giraffes and
zebra are associated with rain through their appearance and sound. A herd of running giraffes make a rain-like noise with their hooves and the stripes of zebra are found on the
water spirits of some religions.
Birds Most birds are considered sacred to African tribes and are very rarely eaten. One reason for this is the lightning bird myth, which states that lightning is a bird striking the Earth while depositing eggs. The shells of ostrich eggs in particular are considered very potent. At Ratho Kroonkop, wing fragments of birds are found, which is very notable in the context of their value.
Reptiles Another legend found across several African cultures is that of the water snake. Many snakes live in watery holes that evoke the idea of them being tied to rain creation. Fish were considered a kind of snake, and bone fragments from them are particularly abundant in the rock tanks of Ratho Kroonkop. Identified species include the smallmouth yellowfish, catfish, squeakers, and yellowfish. == Interpretation in terms of rain control ==
