Eremopezus

The reed grasses of the subfamily Arundinoideae were probably far less widespread in Africa 35 million years ago (Ma) than they are today, but it is fairly likely that other Poales reeds—Cyperaceae (maybe including the ancestors of the Papyrus Sedge Cyperus papyrus), Juncaceae and Typhaceae—grew in aquatic habitats back then already.

The absence of the Great Escarpment for about 450 km (280 miles) to the north of Tzaneen (to reappear on the border between Zimbabwe and Mozambique in the Chimanimani Highlands), is due to a failed westerly branch of the main rift that caused Antarctica to start drifting away from Southern Africa during the break up of Gondwana about 150 million years ago.

About its late Whaingaroan (about 27 million years ago) creation, it says, “The change from estuarine, shallow brackish water conditions (Mangakotuku Formation), to fully marine, open sea, aerobic conditions (Glen Massey Formation) is evidenced by near shore accumulation of the bioclastic Elgood Limestone, onlap of the succeeding Dunphail Siltstone, and subsequent deposition of Ahirau Sandstone in an inner to mid shelf environment.”
