Research interests

My main research interest lies in the reconstruction of Neogene paleolandscapes occupied by early hominins. I rely on extensive fieldwork and geochemical approaches including stable isotope data of hydrogen, carbon, nitrogen and oxygen, as well as clumped isotopes and multi-element analysis in a variety of proxy materials such as (fossil) tooth enamel and pedogenic carbonates. I focus on the wooded savannas of south-eastern Africa (Tanzania, Malawi, Mozambique, South Africa), while I am involved in archaeological, anthropological and paleoecological projects in Indonesia, Syria and Turkey. My goal is to understand the processes that link early hominin (dietary) adaptations to changes in the ecosystem they evolved in.

DFG Project LU 2199/1: Early hominin (plant-based) dietary adaptation in the southern East African Rift

The overarching goal of this project is to reconstruct (Plio-)Pleistocene paleotemperature, vegetation, precipitation and evaporation patterns of hominin localities in the southern part of the East African Rift (Karonga Basin, Malawi and Manyara Basin, Tanzania). I use hydrogen, carbon, oxygen and clumped isotopes on different proxies (fossil tooth enamel of fauna (including early hominins), pedogenic carbonate and modern meteoric waters), I then link these paleoecological patterns with the diet of early hominins Homo rudolfensis and Paranthropus boisei. Results are published in Lüdecke et al., 2018 (PNAS).

Early hominin meat consumption

Information about an individual’s position in the food-web – and with it the incorporation of animal resources in its diet – is reflected in nitrogen isotope ratios (d15N) of organic tissues. To date, these data could only be determined in samples with sufficient amount of collagen, which has poor long-term preservation potential. While d15N has been measured in subfossil and fossil bones, such analyses have been limited to relatively young (typically <100 ka) and exceptionally well-preserved material. We now developed a new method that allows us to investigate nitrogen isotopic composition of enamel bound organic matter material as old as 150 Ma to determine trophic levels. Among others, such as modern African mammals and Mesozoic dinosaurs, I analyze nitrogen isotope data for Australopithecus from the Sterkfontein cave in southern Africa, which represents the first d15N data measured in any early hominin. This data provides a glimpse into the trophic behavior of Pleistocene hominin taxa.

Paleo-Primate-Project Gorongosa

As a research affiliate at the Institute of Cognitive and Evolutionary Anthropology, University of Oxford, I am the leading geochemist of the Paleo-Primate Project Gorongosa (PPG), Mozambique. The poorly-explored Gorongosa area is uniquely positioned in a large geographical gap between the well-studied hominin-yielding sites of the East African Rift in the north and the South African cave localities in the south. The overarching goal of the PPG is the reconstruction of the ecological and evolutionary history of the Gorongosa National Park region from the deep past to the present. Furthermore, the project focuses on primate adaptations to the complex environments of Gorongosa, both past and present. In the first four years of fieldwork, we discovered and started to excavate several fossil sites, which are some of the richest and well-preserved ones in the southern part of the East African Rift.

Research interests

I am a geologist who uses stable isotope geochemistry to quantify paleoelevations of mountain ranges, as well as to reconstruct continental paleoenvironments. I establish the necessary chronological framework using magnetostratigraphy and 40Ar/39Ar geochronology. My goal is to link tectonic processes to changes in paleoenvironmental patterns (vegetation, hydrology, climate, seasonality). I work within the ‘Paleoclimate and Paleoenvironmental Dynamics’ group of Andreas Mulch.

Current research projects

The Neogene paleoaltimetry of central Anatolia 

I employ stable isotope paleoaltimetry to reconstruct central Anatolian topography with the ultimate goal of identifying mechanism(s) of surface uplift as a result of mantle versus crustal processes. Results show that the southern Central Anatolian Plateau (CAP) margin reached similar-to-present elevations of ~2 km by 5 Ma.

Collaborators: D. Whitney (U Minnesota), G. Brocard (U Sydney), C. Teyssier (U Minnesota)

Neogene ecosystems of the present-day Central Anatolian Plateau (CAP)

Stable isotope geochemistry in fluvio-lacustrine sedimentary systems provides information on lake hydrology, as well as on paleoenvironment and paleoclimate. Many of the lakes in the CAP area exhibit evidence for an open hydrology, therefore indicating they were either outward draining (Black Sea, Mediterranean) or into a terminal lake. 

Soil carbonates provide a proxy material for paleovegetation reconstructions. Large variations in stable carbon isotope values indicate the dominance of C4 over C3 carbon fixation in central Anatolia over certain periods in the geological past. 

More recently, I have started to work on mammal tooth enamel from mammal fossil localities in central Anatolia, which provide a means of reconstructing paleodiet and seasonality. The variation in mammalian traits over geological time within nearby mammal localities suggests significant changes in paleohabitats and therefore vegetation and diet.

Collaborators: O. Başoğlu (Gazi U), F. Kaya (U Helsinki), C. Pehlevan (Nevşehir U)

Geochronology of the Central Anatolian Plateau

For many of the fluvio-lacustrine Anatolian basins in which the proxy materials were sampled, I establish new age constraints by combining magnetostratigraphy, 40Ar/39Ar geochronology and existing mammal stratigraphy. The obtained age framework for the studied basins allows the paleoaltimetric and paleoenvironmental data to be put in a spatio-temporal framework.

Collaborators: C. Langereis (Utrecht U), J. Feinberg (U Minnesota), M. Cosca (USGS)

Mountain uplift and biodiversity in Anatolia

The world’s mountain ranges have long been recognized as biodiversity hotspots. In order to relate mountain uplift and environmental changes to biodiversity, I work with macroecologists and macroevolutionary biologists. Paleogeography, mammal diversity, dissimilarity and turnover, as well as paleovegetation and paleoclimate data are being combined to assess the effect of mountain uplift on biodiversity for a case study in Anatolia.

Past Research

Plate tectonic reconstructions and the restoration of the geometries of mountain belts in the greater Black Sea region

Rotational paleomagnetic studies led to the restoration of the original geometries of the Pontides (Turkey) and Lesser Caucasus (Armenia, Georgia) orogens, as well as the Central Anatolian Crystalline Complex (Turkey). Using paleomagnetism, I produced plate tectonic reconstructions for Baltica, the southern Eurasian margin (Crimea, Pontides) and the South Armenian Block. The remagnetized nature of (mostly) marine carbonates caught my special attention. I also examined the Jurassic paleo-subduction zone configuration of the Black Sea region based on 40Ar/39Ar dating and geochemical analysis of Crimean volcanic rocks.

Research interests

My research interest focuses on well dated recordings of paleoenvironmental changes occurring in (restricted) marine water basins during the geological past. My PhD research tackled the ‘conditio sine qua non’ of Earth Sciences: the age control. I was using an integrated stratigraphy approach (magnetostratigraphy, cyclostratigraphy, 40Ar/39Ar dating), resulting in the revised time-scale for the Paratethys domain (the ancient sea of Eurasia). I identified magnetofossil greigite uniquely produced by magnetotactic bacteria, as an essential component for reliable magnetostratigraphic dating in fresh-brackish water systems. An important topic was to quantify the paleoenvironmental changes within the Dacian basin determining 87Sr/86Sr ratios as proxy for continental water input.

Subsequently, I took another step by using organic geochemistry as another working tool. The d13C and dD ratios of molecular biomarkers (n-alkanes and alkenones) measured at multiple locations gave excellent results. I found out that, at the end of the Miocene, the Black Sea was subject to severe drought with extreme evaporation taking place that led to its water level draw.

To summarize, I am scientifically tailored to a multidisciplinary approach. I took the chance of developing extended fieldwork experience (in Romania, Russia, Azerbaijan, Ukraine, Italy, Spain, Croatia, Serbia,Armenia, Greece etc) that, by now, is matched by equally sized laboratory practice.

I am currently working on organic geochemistry (biomarkers). My research focuses on the Miocene because it is a period with important and fast variations of the climate system. The aim of my study is to obtain a viable climatic model (temperatures and water budgets) for the Eurasian domain; a domain which has totally transformed since the early Miocene due to the birth of most of today’s orogen belts

  • Research area: Central Alps and the Swiss Molasse Basin
  • Goal: Reconstruct the paleoelevation of Miocene Central Alps and reveal climatic and paleoenvironmental conditions of Central Europe during the Neogene period
  • Methods: d-d paleoaltimetry, δ18O and δ13C stable isotopes, carbonate clumped (D47) thermometry

My research area is located in the Central Alps and the adjacent Swiss Molasse Basin, the western part of the northern Alpine foreland Basin. This region catches deposits of the Central Alps which were eroded due to the orogen uplift. My focus is on terrestrial carbonate-rich sediments of Miocene age which were deposited in large fluvial megafan deltas. Miocene climatic conditions enabled the basin-wide formation of paleosols rich in pedogenic carbonate nodules. Those authigenic minerals are perfectly suitable for analyses of standard stable isotopes (δ18O and δ13C) and clumped isotopes (D47) and tell us about prevailing paleotemperatures and paleoenvironmental conditions at the time and site of carbonate growth. One of my projects targets revealing of the Mid-Miocene Climatic Optimum with the help of carbonate clumped (D47) based thermometry. To understand how the temperature evolved during time is an important feature of my second project: reconstruction of the Miocene Alpine uplift with the d-d paleoaltimetry approach.

Research interests and current projects

One of my goals is to develop and apply new methods of paleoenvironmental reconstruction. My focus is the analysis of continental climate factors such as temperatures and isotopic compositions of fluids, e.g. on tooth enamel and pedogenic carbonates. Apart from fieldwork and operational support of the Goethe University-Senckenberg BiK-F Joint Stable Isotope Facility, I concentrate my efforts on methodological work on the geochemical proxy ‘clumped isotope’. Current research topics are the terrestrial climate evolution during the Middle Miocene Climatic Transition and method development of the combined high-precision ∆48 and ∆47 analysis of carbonates.

Terrestrial climate evolution during the Middle Miocene Climatic Transition

A comprehensive and well-dated terrestrial clumped isotope (Δ47) paleosoil carbonate dataset from Southern Europe (Spain) that ranges from 13 to 15 Ma was analyzed for paleoclimate reconstruction. The data covers the interval of the Middle Miocene Climate Transition (MCT) and shows a large decline in Δ47-based temperatures at 13.9 Ma indicating a major drop in continental temperatures. The Δ47 data further shows a highly dynamic transition into the MCT which can be linked to oceanic δ13C and δ18O isotope records.

Combined high-precision ∆48 and ∆47 analysis of carbonates

High-precision analysis of the excess abundance (relative to the stochastic distribution) of mass 48 isotopologues in CO2 evolved from acid digestion of carbonates (∆48) was first shown to be feasible using a 253 Plus™ gas source mass spectrometer. Follow up studies are now focusing on the deciphering of thermodynamics and possible kinetic effects during carbonate precipitation as well as back-calculating kinetic pathways of samples to derive pristine precipitation temperatures.

Clumped and oxygen isotope temperature calibration for biogenic apatite

Clumped isotope data from carbonated apatite from in vivo and in vitro samples were analyzed to refine the relationship between mineral growth temperature and carbonate clumped isotopic composition47). Δ47, δ18O and δ13C data were obtained from phosphoric acid digestion of chemically untreated teeth from an African elephant, Greenland sharks, sand tiger sharks and synthetic apatites. The temperature dependent oxygen isotope fractionation between structural carbonate in synthesized carbonated hydroxylapatites (CHAP) and water was calculated between 7 °C and 80 °C. Both new calibrations where applied to a modern Greenland shark and a fossil Carcharodon megalodon for reconstructing paleotemperatures and oxygen isotopic values of seawater.
