A guide to the Lower Jurassic is available on the Geological Society website (click here).

Images from the JNCC volume “British Lower Jurassic Stratigraphy” can be found here.

A guide to the Middle and Upper Jurassic can be found on the Geological Society website (click here).

Images from the JNCC volume “British Middle Jurassic Stratigraphy” can be found here.

The story of the Middle Jurassic dinosaur from Rutland, Cetiosaurus oxoniensis, can be found on the website of Leicester’s New Walk Museum (click here).

Images from the JNCC volume “British Upper Jurassic Stratigraphy” can be found here.

A Geological History of Britain – part 7

New Red Sandstones – the Permian and Triassic

The slides from the lecture can be found here: 2012_GHB_Lect7

An excellent overview of the Permian and Triassic of the UK, listing the best places to see rocks of this interval, can be found on the JNCC website here.

An overview of the Permian can be found at the University of California Museum of Palaeontology website (Click here).  Its Triassic page can be found here.

The Geological Society introduction to the Permian can be found here, and its guide to the Triassic here.

Images from the JNCC book “Marine Permian of England” can be found here.

Detailed information on the origins of the Permo-Triassic minerals found in the limestones of the Great Orme, Llandudno, North Wales can be found here.

The first of two articles I’ve written on how Permian reptile tracks from the sandstones of Dumfries & Galloway led to the birth of ichnology can be found here.

A Geological History of Britain – part 6

Lime, sand and coal – the Carboniferous

The lecture slides for the class can be found here: 2012_GHB_Lect6_bw

An overview of the Carboniferous period is provided on the Natural England website here.

A free publication on the geology of the North Pennines can be found here.

A brief overview of the Yoredale Group in Northumberland National Park can be found here.

The story of Carboniferous oil and the first well in mainland Britain can be found here.

A Geological History of Britain – part 5

Silurian and Devonian – closure of Iapetus and the building of Britain

The lecture notes for class 5 are available as a pdf here: 2012_GHB_Lect5

Images from the GCR book “British Silurian Stratigraphy” can be found here.  They include a comparison of Murchison, Sedgwick and Lapworth’s stratigraphies with that recognized in the late 20th Century (which has since been modified, of course!).

Images from the GCR book “Caledonian Igneous Rocks of Great Britain” can be found here.  There are a LOT of pictures, and they include the Shetland and other Scottish ophiolites, and the various Ordovician-Silurian-Devonian igneous rocks of Scotland, the Lake District and Wales.

Images from the GCR book “Caledonian Structures in Britain South of the Midland Valley” can be found here.  They cover the Caledonian structural geology of the Southern Uplands, the Lake District, and Wales.

A Scottish Natural Heritage guide to the geology of south-west Scotland, including the Southern Uplands, can be downloaded by clicking here.  The SNH website includes a fair amount of other information on Scotland’s geology.

Charles Lapworth’s interpretation of the structure of the Southern Uplands can be found here.  A short biography of the man can be found here.

Images from the GCR book “The Old Red Sandstone of Great Britain” can be found here.  The Devonian fishes of Caithness and the Moray Firth are covered in detail in Chapter 6.

A Geological History of Britain – additional resources

Below is a list of general geological resources that might be of use or interest.

Geo-nealogy, or Where Do You Think You Were?

For those wanting online geological maps of the UK, the Geology of Britain viewer (BGS Open Geoscience) can be found here.

The Geological Society’s Brief Summary of British Stratigraphy can be found here.

A good overview of the geology of Plymouth (which helps make sense of the confusing geological map) can be downloaded here.

Online geological map resources for the USA (courtesy of the US Geological Survey) can be found here.

More specifically, geological maps of the San Francisco Bay region can be found here, and of Oakland here.

An online, interactive geological atlas of New Zealand can be found here.

Other useful links:

If you’re having trouble with all the different names for different intervals of geological time, the GeoWhen database is very useful. It aims to clear up the confusion over regional, national and archaic terms, and can be found here.

GeoScenic, the National Archive for Geological Photographs, can be found here. You can search for, view and download thousands of images from the vaults of the British Geological Survey.

The GCR (Geological Conservation Review) database can be found here. You can search for national geological sites of importance, some of which (e.g. Flamborough Head) have site accounts providing details on the geology of that locality.

The GCR also has an Image Bank, where the photos and figures from many of its geological volumes are available.  These vary from British Silurian Stratigraphy to the Quaternary of the Thames, via the Fossil Reptiles of Great Britain.  The full list of available volumes can be found here.
