Late Pleistocene floras from Earith, Huntingdonshire
1Department of Geology, University of Birmingham.
Summary
Last-glacial plant remains from the River Ouse reveal a unique flora adapted to cold climates with permafrost. This ancient vegetation indicates surprisingly warm summers and the presence of salt in the East Anglian fenland.
Area of Science:
- Paleobotany
- Quaternary Geology
- Paleoclimatology
Background:
- Organic beds of Last-glacial age discovered in River Ouse fluviatile gravel.
- Radiocarbon dating places these beds in the early Weichselian period.
- Subsequent cryoturbation and ice wedge casts indicate severe cold and permafrost.
Purpose of the Study:
- To analyze macroscopic plant remains from Last-glacial organic beds.
- To reconstruct the paleoenvironment and climate of the East Anglian fenland.
- To investigate the taxonomy and ecology of identified plant species.
Main Methods:
- Excavation and dating of organic beds.
- Analysis of macroscopic plant fossils.
- Pollen analysis.
- Ecological and taxonomic assessment of flora.
Main Results:
- Vegetation dominated by dwarf willows and open-habitat herbs.
- Presence of northern and southern distributional flora, including halophytes.
- Evidence of salt in the substrate and discontinuous permafrost.
- Reconstructed climate: warm summers, cold winters, mean annual temperature below 0°C.
Conclusions:
- The flora reflects open glacial habitats and a climate with significant temperature fluctuations.
- The presence of halophytes suggests saline conditions in the fenland.
- The findings provide insights into Last-glacial ecosystems and paleoclimates in Britain.

02:56The Fossil Record
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...
01:50Global Climate Change
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
00:48Optimal Foraging
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.
02:35What is Evolutionary History?
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.
02:26Non-vascular Seedless Plants
The diverse plant life on Earth—consisting of nearly 400,000 species—can be divided into three broad categories based on biological characteristics: nonvascular, seedless vascular, and seed plants.
02:31Habitat Fragmentation
Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.
