Abstract

Macroscopic fossil plants from the Upper Laetolil Beds, Laetoli, Tanzania, are described and where possible identified. Leaf impressions were recovered from the top of Tuff 8 at Locality 16 and show only primary and secondary venation. While many cannot be identified, some appear to belong to the Euphorbiaceae. Casts of fruits and seeds occur in almost all localities but exhibit only external features. The most common seed is probably that of Boscia coriacea (Capparaceae). Others have been tentatively identified as Papilionaceae, Ximenia species (Olacaceae), Lauraceae and Celtis africana (Celtidaceae). Monocot leaves, thorns of Rosaceae or Papilionaceae and a large sedge rhizome with basal culms are also described. The macrofossils represent a diverse flora with forest elements (Lauraceae, Celtidaceae) and dry open woodland elements (Capparaceae, Leguminosae) during 3.8–3.5 Ma. The sedge culm implies a wetland or springs at some time in the Upper Laetolil period.

Acknowledgements

Macroplant fossils have been collected over many field seasons by field teams and their assistance is appreciated. Research Permits were granted by the Tanzanian Commission for Science and Technology (COSTECH), Tanzanian Department of Antiquities and the Ngorongoro Conservation Area Authority. The financial assistance of the NSF grants to Terry Harrison (BCS-9903434 and BCS-0308513) and from PAST (the South African Palaeontological Scientific Trust) to the author are gratefully acknowledged.
