title = "Modern and Ancient Animal Traces in the Extreme Environments of Lake Magadi and Nasikie Engida, Kenya Rift Valley",
abstract = "Modern Lake Magadi and Nasikie Engida in the inner southern Kenya Rift exemplify the extreme conditions in some continental rift settings, with abundant inflow from hot springs and magmatic CO2, producing high-carbonate-bicarbonate, high-sodium waters with little calcium in a semi-arid closed lake basin. Hypersalinity, hyperalkalinity, and hydrothermal conditions characterize the modern lake and lake margins, and also contributed to the environmental conditions represented by the Pleistocene to Holocene sedimentary record of the basin. Micro- and macro-organisms are restricted in diversity and distribution in the modern lake basin. This study documents modern animal traces present in lake-margin sites around Lake Magadi and Nasikie Engida, and those preserved in Pleistocene and Holocene sediment outcrops in the Magadi Basin. These findings are then applied to the interpretation of examples preserved in drill-cores (HSPDP-MAG14) that span the Pleistocene to recent sedimentary record of Lake Magadi. Observed associations among animal traces, substrates, and environmental conditions in the modern sedimentary lake-margin environments help to interpret ancient lacustrine sediments in the geologic record.",

note = "Funding information: Beth Gierlowski-Kordesch inspired us in our approach to investigating modern and ancient traces in heterogeneous environments in the Kenya Rift, and her scientific contributions, encouragement, and friendship through the years will always be cherished. We are very grateful for scientific contributions and support provided by colleagues from the Hominin Sites and Paleolakes Drilling Project, the Smithsonian Institution Olorgesailie Drilling Project, and LacCore Laboratories at the University of Minnesota. Shangde Luo (National Cheng-Kung University) and Chuan-Chou Shen (National Taiwan University) are gratefully acknowledged for significant contributions by dating the cherts. J.J.S., R.W.R., and L.A.B. were supported by the Natural Sciences and Engineering Research Council of Canada (NSERC to LAB: grant 311726-13; RWR: grant GP629) and a PhD scholarship to J.J.S. R.B.O. acknowledges the Hong Kong Research Grants Council for continued support (HKBU12300815 and 12304018). M.S. gratefully acknowledges support from the Swiss National Science Foundation grant P300P2 158501. Drilling of the MAG14 cores was funded by ICDP and NSF grants (EAR-1123942, BCS-1241859, EAR-1115118, and EAR-1338553). Analyses were supported by the Hong Kong Research Grants Council (HKBU-201912 and 12304018). We thank the National Museums of Kenya, the Kenyan National Council for Science and Technology, the Kenyan Ministry of Mines, and the National Environmental Management Authority of Kenya for providing permits. Tata Chemicals Magadi Limited and the Magadi Administrative District of Kajiado County provided local support during drilling and field research. This is publication #30 of the Hominin Sites and Paleolakes Drilling Project (HSPDP).
