| Description | He has made slight progress on the relative ages of the Pleistocene deposits in the Kanam-Kanjera area, dependent on two scraps of elephant from Kagur. Kent and Leakey think that the localities of Fish Cliff, Rawi and Kagur are all about the same age. Kagur is divided into Sites 1-4 and Kagur Flats - he is uncertain that they are equivalent, but assumes so, or else the Flats are a delta into which fossils were washed from the Kagur beds proper. He has a high-crowned elephant tooth from Kagur Site 4 which does not look like the Olduvai form. He has two fragments of a low-crowned form from the Flats. If his assumpion on fauna uniformity are correct, this is the same association reported by Leakey to the Cambridge conference and suggests that Kanam East, West, Rawi, Fish Cliff, Kagur and Kagur Flats are all older than Olduvai. He also has an approximate date for what Leakey called the Laetolil Beds, south-west of Olduvai, what the Germans called Vogel Fluss and the English maps Vogel. Lava caps indicate that these beds are older than Olduvai. As Fuchs said, it does not follow that the two lava flows are the same. Hopwood has proved the identity of the elephant from Laetolil with that of Olduvai: both are E. antiquius recki. Laetolil and Olduvai are of the same general Middle Pleistocene period. He is sorry that he will not hear Professor Heim's lecture. He has just sent a short note to the Geological Magazine connected with the subject of his first lecture and he sends a rough carbon copy to Boswell. |
