A colour pdf of the notes from the class can be downloaded here: 2013_YorksDales_colour. I will try to add a black and white version soon.
Below are a selection of links relevant to Yorkshire Dales geology and fossils…
To start with, if you want a copy of the latest (2013) geological time scale, click here. And if you want to get a copy of the British Geological Survey poster, Climate Through Time, click here.
The British Geological Survey (BGS) provides an interactive geological map of Britain, which enables you to find out what rocks are where. The survey also provides a lexicon to explain the names of the different rock units.
Yorkshire Dales geology and fossils
The North Yorkshire Geodiversity Project has produced a website called Your Dales Rocks, providing information on all sorts of geological aspects of the Dales.
A paper by Bond (1949) on the limestones of Cracoe can be read here: FYD2013_Bond1949_Cracoe_limestones, whilst a short summary of the reef knoll SSSI at Swinden Quarry can be downloaded here.
A number of files and links providing information on the geology of the Malham area can be found on the National Park website here. The Field Studies Council (FSC) also provides an electronic guide to Malham geology.
Details of a Cotterdale (Wensleydale) walk on which you might find fossilized ‘Stigmaria‘ roots can be found on the Dalesman website here.
The Craven & Pendle Geological Society provides plenty of useful information on Carboniferous fossils, including a short guide to the ammonoids of Stonehead Beck, Cowling, North Yorkshire.
Crinoid-rich ‘Swaledale stone’ has been quarried for centuries. Some nice images can be seen on the Britannicus Stone website here.

The Carboniferous coal swamps are well-explained by Ben Slater on the Palaeocast website here.
The vertebrate palaeontologist Darren Naish has written a series of general interest articles on the origins of tetrapods, including a piece on temnospondyls that can be read here.
Professor Jenny Clack of Cambridge University is one of the world’s leading experts on early tetrapods. Her website, which has lots of useful info, can be found here. Her research also featured on the BBC series Beautiful Minds.
The Joggins Fossil Cliffs of Nova Scotia have yielded all sorts of amazing early terrestrial fossils and are a UNESCO World Heritage site. The website can be found here.
The website for the new TW:eed project (Tetrapod World: early evolution and diversification) can be found here.
