We report a new Cretaceous multituberculate mammal with 3 D auditory bones preserved. Along with other fossil and extant mammals, the unequivocal auditory bones display features potentially representing ancestral phenotypes of the mammalian middle ear. These phenotypes show that the ectotympanic and the malleus-incus complex changed notably during their retreating from the dentary at various evolutionary stages and suggest convergent evolution of some features to extant mammals. In contrast, the incudomalleolar joint was conservative in having a braced hinge configuration, which narrows the morphological gap between the quadroarticular jaw joint of non-mammalian cynodonts and the incudomalleolar articulations of extant mammals. The saddle-shaped and abutting malleus-incus complexes in therians and monotremes, respectively, could have evolved from the braced hinge joint *** evolutionary changes recorded in the Mesozoic mammals are largely consistent with the middle ear morphogenesis during the ontogeny of extant mammals, supporting the relation between evolution and development.

This study determined the physico-chemical and bacterial quality of raw (bore-hole, springs, wells) and tap water sources from Nyaruzinga wetland for domestic use in Bushenyi Municipality. Forty samples of raw water were randomly collected from Kacuncu, Kyeitembe and Kikuba tributaries of the wetland and 40 samples of tap water generated from the same wetland were randomly drawn from Ishaka, Nyakabirizi and Central divisions of the Municipality. The samples were analyzed for apparent colour (AC), turbidity, electrical conductivity (EC), total hardness, pH, total iron, residual alum, free residual chlorine and faecal coliforms using standard methods and their values compared with standard local UNBS (2008) and international WHO (2011) drinking water quality guidelines. The results showed that the mean pH of the protected spring below Kikuba hill (5.21);the AC (Pt/Co) of the borehole below Bweranyangi Junior School (17.28) and the surface well below Nyandozo Primary School (157.58) both situated in Kacuncu as well as the free residual chlorine (mg/L) in tap water at Kanyamabona Trading Centre, Ishaka division (0.192) were below the standard values of WHO (pH, 6.0 - 8.0;free residual chlorine, 0.2 - 0.5) and UNBS (AC, <15). The electrical conductivity, EC (μS/cm) and total hardness (mg/L) of all the selected water sources were within the WHO standards (EC, <1500 (raw water), 0 - 300 (tap water);total hardness, <1500 (raw water), <100 (tap water)). The residual alum (mg/L) in all the tap water sources was also within the WHO guideline (<0.2). On the other hand, the turbidity (27.38 NTUs) and total iron content (0.32 mg/L) of the surface well below Nyandozo Primary School were above WHO guidelines of <15 and <0.3 respectively. Furthermore, the mean faecal coliform counts (CFU/100 ml) in the surface well below Nyandozo Primary School (6.90) and the borehole below Bweranyangi Junior School (16.83) including the surface well below Kyeitembe Trading Centre (9.25) were above
