However it is unclear what the reason for this apparent absence is. This is especially the case considering that during the Eemian, temperatures in north-west Europe are known to have been several degrees warmer than even today, making it a potent habitat for early hominins. Several theories have existed in order to explain this, which include a complete absence in north-west Europe due to constraints in mental fortitude and an ecology that would have been unsuited for hominins to survive, as well as an early disappearance of the land bridge that connected France to Great Britain during the glacial periods. This was based on the fact that hominin sites that date back to the Eemian are exceedingly rare in north-west Europe, with the first examples only having been discovered relatively recently. This thesis aims to further explore these possibilities by making an ecological reconstruction of the site of Waziers, which is located in northern France and dates back to the Eemian. It does this based on carpological and palynological material that was found at the site. In addition to this a correlation of pollen records was made using several other Eemian type sites located in both France and Great Britain. This data is then combined with pre existing literature of other Eemian sites in north-west Europe with signs of hominin activity, in order to correlate these sites together so that Waziers can be placed in a wider chronological and climatological framework. In addition to this several other biological factors that were encountered at Waziers, are compared to the climatological conditions that were prevalent in the wider region as well. In doing so it was found the hominin activity that was detected at Waziers took place very early in the Eemian, when the stage had just transitioned from the Saalian glacial stage. In addition to this it could also be concluded that this early period was much warmer than originally anticipated. This could be seen in the presence of such indicator taxa as Lemna cf. minor, Hedera helix, and Salvinia natans, which could all be found within the vegetational record of the site. Because of these factors it is concluded that while there was already a hominin presence very early in the Eemian interglacial, which indicates that climatological conditions were at least adequate to sustain a hominin presence. It also shows that these hominins did not lack the mental fortitude to exist in these conditions, as was suggested by earlier theories. Despite this it is likely that, due to the high temperatures melting the land based ice locked in the glaciers during the Saalian, the land bridge that had existed between France and Britain during the glacial stage had already disappeared, inhibiting further hominin dispersal to the British Isles.Show less

Due to its location on a dry loessy high bluff zone on the Western bank of the river Danube, a sedimentary environment that is appropriate for pollen preservation to conduct pollen analysis was not found around the site (Sumegi & Bodor, 2000). Instead, regional pollen analysis has been conducted to study the environment relating to the Százhalombatta-Földvár site. This regional sediment sample was obtained by coring from an oxbow lake about 500 m away from the site. During the Százhalombatta-Földvár excavation in 2022, however, the lithological examination of the floor sediment from [House] 9000 indicated the possibility for pollen preservation, followed by palynological investigation including the comparison to the regional pollen record. This unconventional method of pollen analysis was successfully conducted, yielding a well-preserved pollen assemblage. The methods of pollen analysis applied are pollen counts, taxonomic identification and states of preservation analysis. These methods indicate that the well-preserved pollen assemblage obtained from the unconventional context does not reflect the pollen assemblage from the oxbow lake pollen record. Especially the absence of arboreal pollen at the site compared to that recorded in the regional pollen data is conspicuous. These results allow us to discuss and investigate the sample from [House] 9000. Specifically, in the sample, taphonomic agents contributing to the absence of arboreal pollen in contrast with the regional palynological signal are analysed and the predominance of Poaceae is explained with taphonomic processes. Furthermore, the taphonomic agents causing the primary pollen preservation states are investigated and the taphonomic processes resulting in the preservation biases are explored in archaeological interpretation. In consequence, the investigation of the taphonomic processes suggests anthropogenic agents causing the discrepancy and bias in the pollen assemblage with the construction and materials used for [House] 9000. The pollen preservation state analysis revealed that the primary states of pollen preservation are degraded and folded. These in turn are evidence of the taphonomic processes of oxidisation and physical stress, which in combination with archaeological evidence suggests anthropogenic activities as cause. To conclude, this thesis could contribute to multi-disciplinary research and greater understanding of the Bronze Age site, Százhalombatta-Földvár. Moreover, it demonstrates new potential of palynological analysis employing an innovative sampling method that directly relates to the human activities at the site. The results of this thesis have the potential to stimulate further application of this new approach.Show less

These pollen diagrams showed two distinct local pollen assemblage zones (LPAZ) throughout the sequence. LPAZ VVP-1 showed a Pinus dominated coniferous forest with high amounts of Corylus that was slowly transitioning into a mixed deciduous forest. The steppe landscape was slowly disappearing and the Rhine or one of its tributaries and possibly a lake were likely nearby. LPAZ VVP-2 showed a now Corylus dominated mixed deciduous forest and the likely complete disappearance of the steppe. Alnus marshes now also played a dominant role. The river was likely still nearby. These results provide a more detailed picture of the vegetation of the Vrouw Vennepolder. In order to add a more precise timescale to the sampled sequence the sediments and the biostratigraphy were compared to the geological events and biostratigraphy of the western Netherlands during the Late Pleistocene and Early Holocene. This revealed that the sequence started with LPAZ VVP-1 in the Late Pleistocene during the Younger Dryas and possibly continued in to the transition to the Holocene Preboreal. After a hiatus in the Preboreal the sequence continued with LPAZ VVP-2 in the Boreal period which probably ended at the transition to the Atlantic period. The depths of the sediments were also correlated to the sea-level curve of the Rhine-Meuse delta in order to provide further dating information. This method suggested a much younger and shorter sequence in the Atlantic, but given the difficulties of this method it is better to rely on the information provided by the sediments and the biostratigraphy. These results provide a more detailed timescale for the sampled sequence. In order to determine the possibility of Paleolithic and Mesolithic groups visiting the Vrouw Vennepolder the Vrouw Vennepolder was analyzed in regards to the resources and the ecological challenges it could provide. The tough ecological challenges it provides in the vicinity of the corings due to wetness mean that it is unlikely that humans built settlements right there. They could have built them elsewhere in the Vrouw Vennepolder or outside of it and then used the area for hunting and foraging. The Vrouw Vennepolder would however have provided a large amount of resources, Corylus nuts in particular, meaning that nearby humans are likely to have exploited the area. The early and dominant presence of Corylus in the pollen diagrams could be the result of humans interacting with the environment through burning, but it is far from definitive. These results do not provide evidence for human occupation or exploitation of the Vrouw Vennepolder, but exploitation at least seems very likely.Show less

Using this characteristic, palynologist research the past environments and human-environment relations. For archaeology this is crucial information and often a general part of research on a site. As was the case at the Bronze Age burial landscape at Oss-Gewandeweg. At this site, only remains of burial mounds were left due to agricultural levelling. The remaining features, circular ditch fills were sampled for palynological analysis. However, the samples were taken from a sandy depositional context which is unideal for pollen and spore preservation. In this thesis, the reliability of these samples is assessed. If the samples are not reliable they will portray an false vegetational reconstruction. This has scientific and social implications. Palynology is plays a role in the climate change debate and should be used wrongly because of this societal value. Two research questions have been formulated in order to fulfil this goal. The first research question was aimed to study the taphonomy of the palynomorphs and the effect the sandy depositional context had on the preservation. Besides the typical production bias and dispersal bias, the preservation context increases the differential degradation bias. The sand grains provide gaps through which water can leach and oxidize the pollen. The more oxidized the pollen are, the more susceptible to micro-organism attack. Biological degradation is thus also increased. The preservation states of the pollen in the samples also illustrated the poor preservation. The second research question included a comparative analysis between the ecological reconstruction based on the samples form Oss-Gewandeweg and Oss-Mettegeul, just five kilometres apart. The lower taxa diversity, absence of certain taxa and lower proportionality of certain taxa all point to a worse preservation context compared to the samples at Oss-Mettegeul. Recommendations for future research is to sample sediment which is dark-coloured and fine-grained. If samples from the Bronze Age ditch fill are required, phytolith analysis would be a great alternative. Phytoliths are inorganic and preserve better than pollen, spores and macrofossils.Show less

It is located near the Gartempe river. Nowadays it is a small river but in the past it influenced the environment in the valley. There is evidence that correlates the river to the site in the form of pebbles and flint but virtually nothing is known about the landscape shaped by the river during occupation of the cave. This thesis is an initial research and tries to comprehend the difficult fluvial landscape here. By mapping the fluvial history research questions can be answered regarding the influence of the environment in the Gartempe valley on human behaviour. With an augering transect eight different units were distinguished of fluvial depositions and erosion and showed the existence of two palaeochannels buried beneath the surface. The oldest channel had an infilling of peat and was studied in the form of a palynological research. The general picture, which consisted of Pinus and Betula, dated the infilling to the Allerød or Preboreal period. This was done by comparing it to several other sites in France which include the same environment. The local environment in this period shows that the channel got cut off and was not active anymore in this phase. There was still open water present but the accumulation of peat was in progress. The valley would have been characterised by wetland conditions. Two phases identified in this thesis could be of interest for the research at Les Cottés. One interpretation is that the terrace in front of the site is older than the research at Les Cottés and this means that the Pleistocene surface would be buried beneath current floodplain deposits. This terrace in front of the site could have been used as an overview point. The other interpretation is that the terrace was shaped after the occupation at Les Cottes. This would mean that the relative height difference between the cave and the site was very small. Both interpretations would have an impact on the archaeology. This shows that the Gartempe influences could have been bigger in the past.Show less
