Plotopteridae they became extinct. That they became extinct at the same time as the giant penguins of the Southern Hemisphere, which also coincided with the radiation of the seals and dolphins, has led to speculation that the expansion of marine mammals was responsible for the extinction of the Plotopteridae, though this has not been formally tested. Plotopteridae Plotopteridae is the name of an extinct family of flightless seabirds from the order Suliformes.

Southern black tit Southern black tit The southern black tit or simply black tit ("Melaniparus niger") is a species of bird in the tit family Paridae, which is native to woodland habitats in southern Africa. It occurs chiefly in tropical and subtropical savanna woodland, in a semicircular arc from Angola to the Eastern Cape, South Africa.

It is especially common in the woodlands of western Zimbabwe, where densities can reach as high as fifty birds per square kilometre. The southern black tit, unlike parids of the Northern Hemisphere
