Tetrapod World: early evolution and diversification
Discovering how tetrapods splashed out!

The TW:eed Project was an NERC-funded scientific research programme studying fossils and environments from the Early Carboniferous Tournaisian Stage, roughly 350 million years ago. Teams of experts from the Universities of Cambridge, Leicester and Southampton, the British Geological Survey and National Museums of Scotland collaborated to study some spectacular recently-discovered fossils which filled a significant gap (Romer's Gap) in our understanding of how tetrapods moved from water onto land, the other animals and plants that existed at that time, and the environment in which these changes took place.
The project consisted of teams working on the palaeontology, sedimentology, stratigraphy, palynology and performing stable isotope analysis, so that we could discover not only how tetrapods became terrestrial, but also what the environment, plants and other animals were like and how they changed in parallel with the tetrapods.
We also worked with experts in a number of other universities and institutions, both in the UK and abroad. Please see the Project Partners and Canadian Partners pages.
Our project blog is at www.tetrapodworld.com , but is no longer maintained. The Project Facebook page is also rather static these days.
The funding for this project has now run out, but the work continues. I will update this site when new results are published. For now, I've distributed a newsletter, No. 14, which you can download from the
This website is hosted by the British Geological Survey and for the past six years my IT contact at the BGS has been Gemma Nash, who has given me tremendous support and assistance in that time. Sadly for us, she's moving to a new job at the Centre for Ecology and Hydrology,in Edinburgh. I'd like to say a big "Thank you and good luck!" to Gemma and also "Hi" to her replacement, Wayne Shelley.
