The palaeokarst system of Bolt's Farm, Gauteng Province, South Africa, is endowed with numerous fossiliferous Plio-Pleistocene deposits. Among them, the mid-Pliocene locus of BPA (Brad Pit A) has yielded a hypsodont upper molar which exhibits a rodent-like wear pattern, but is not a rodent. In several aspects, it recalls macroscelidids and could fit in occlusal morphology with the lower teeth of Mylomygale spiersi , described on the basis of a mandible from Norlim Cave close to the Taung Limeworks, which yielded the holotype of Australopithecus africanus. This upper molar could be attributed to Mylomygale , a taxon represented by only three specimens. The hypsodonty of the molar and the wear pattern suggest that, at Bolt's Farm, Mylomygale was feeding on tough food and that some herbaceous patches might have occurred in the environment. Moreover our scans reveal that the holotype of Mylomygale possessed an m/3, previously unrecognized. • The paper interprets a new specimen from Pliocene deposits at Bolt's Farm (South Africa) attributed to Mylomygale , an extinct genus of sengi. • It is of special interest for two reasons - Mylomygale is known by only two other specimens of uncertain age; the Bolt's Farm specimen is the first recorded upper tooth of this micro-cursorial mammal. • The new specimen suggests that Mylomygale is possibly linked phylogenetically to Early Miocene Myohyracidae.

Wastewater treatment facilities are often overlooked as a valuable and sustainable energy source with limited literature available on the methodologies used for identifying energy recovery potential at these locations. The lack of research on methodologies to identify potential for energy recovery with limited available data is especially prevalent. This paper aims to address this gap in research by reviewing previous studies that have evaluated the hydropower potential, with a focus specifically on the evaluation of hydropower potential at wastewater treatment works and the technologies most suitable for these sites. Additionally a new methodology was proposed for the assessment of South African wastewater treatment works with the aim of quantifying the potential of this unconventional opportunity when limited access to data poses a challenge. The developed wastewater treatment works evaluation framework was applied to all municipal wastewater treatment works in the Gauteng province to identify a first order estimate of 130 kW–884 kW hydropower potential available in the province. • Review of hydropower evaluation methods. • Review of hydropower technologies at wastewater treatment works. • Generic wastewater treatment works evaluation framework to quantify potential. • Criteria within the framework alleviate problems associated with limited data. • Framework criteria are validated according to the study area under investigation.
