- Isityumzi mlomomde is a weakly described fossil lungfish based on one complete parasphenoid, tooth plates fragments and scales from the Late Devonian Sarcopterygians (lobe finned fishes). It represents the only record of Late Devonian lungfish remains from western Gondwana. This novel species was described through an international collaboration from the world renowned Waterloo Farm lagerstätte in the former Grahamstown (Makhanda) of the Eastern Cape province, South Africa. The type material for this genus was excavated from a meta-layer of the black shale layer located in a predominantly arenaceous Witpoort Formation corresponding to the Famennian age. Lungfish are believed to have solely originated from tropical to warm temperate regions, however, evidence from the Isityumzi mlomomde adds a bigger circle of information to the current perception as evidence from these now suggests that lungfishes originated from the high palaeolatitude fauna located at 70° latitude and possibly further south. This was the position of now Waterloo Farm lagerstätte in what was once Gondwana landmass. Isityumzi mlomomde is further believed to have coexisted with the tetrapods of the Famennian in an estuarine ecosystem environment as seen through the Waterloo Farm lagerstätte's geological lens.
