"There seems no reason to doubt that the lacustrine beds were laid down in an extension of lake Manyara, which now lies at a level 300 to 350 feet below. The extension of other African lakes in the middle and lower Pleistocene pluvial periods is already well known, and the present study, although restricted to the relatively small area of known exposures, indicates that Manyara had a similar history."
