On the 18th September 2018, I attended the Collectors, Collections and the Geology of Southwest Britain meeting. This joint meeting between the Geological Curators’ Group (GCG) and the History of Geology Group (HoGG) was held at the Bath Royal Literary and Scientific Institution (BRLSI), and it was also my first ever GCG event! If you have an interest in British geology, you probably know that the southwest of Britain has amazing geology, but this meeting – with around 80 attendees – also looked at the people who have dedicated their lives to exploring this geologically diverse region.
The day started off with a keynote speech from Steve Etches who spent over 35 years collecting fossils from the Jurassic Kimmeridge Clay deposits of southwest England. His collection of over 2,300 fossils found an exciting new home in 2016; the Etches Collection museum in Kimmeridge, Dorset. It was interesting to find out about the difficulties associated with starting a museum from scratch, but despite the initial challenges, the museum looks incredible and is filled with a diverse array of scientifically important specimens.
Many of the talks focused on the enthusiastic collectors of the southwest. My favourite story was about Charles Moore (1815-1881), a palaeontologist from Ilminster, Somerset. In 1858, he purchased three tonnes of gravel from Holwell, Somerset for 55 shillings. This massive purchase turned out to be filled with Rhaetian (208.5 to 201.3 million years old) fish, mammal and reptile fossils. Moore also collected fossils from the Lower Jurassic limestone of Strawberry Bank in Ilminster, and these fossils are now cared for by our hosts, the BRLSI. During the coffee break, Matt Williams (the BRLSI collections manger) showed us a selection of Moore’s stunning fossils.
As a mineral enthusiast, I really enjoyed the talks about the mineral collectors of the area. Sir Francis Basset (1757-1835) collected many minerals from Cornwall since his estate included several mines. Basset’s collection contained classic Cornish minerals such as cassiterite, native copper, siderite and olivenite; some of these were donated to the BRLSI in 1826. Another Cornish mineral collector, Richard Talling (1820-1883), collected minerals when mining activity in Cornwall was high. Between the 1850s and 1860s, Talling sold some of his minerals to the British Museum for £20-100 per lot, which is a fortune because the annual wage at the time was just £40-90 per year.
Throughout the day, there were chances to view posters about fossil collectors, mineral collectors, scientific photography, hydrogeology and even the geology of gravestones!
Other talks covered a wide range of geological time periods. Around 435 million years ago, Beacon Hill in Somerset was a volcanic arc similar to the Lesser Antilles in the Caribbean. During the Late Triassic, spores of Naiadita sp. (a type of liverwort) floated across the Bristol region. Then we learnt about the ice age caves of Pleistocene Plymouth where humans, hyenas, cave lions, wolves and woolly rhinos roamed.
The relationships between geology and architecture were discussed with presentations about the geological origins of the limestones used by the Romans as building stones in Bath (if you look closely at the stones, you’ll find fossils and sedimentary structures), and how the construction of Brunel’s Great Western Main Line led to the discovery of exceptional fossils in 1841. For cartography fans, there were three talks about geological maps. In 1864, William Sanders (1799-1875) published a 720 square mile geological map of Bristol and surrounding areas which would have cost £300 in today’s money.
So what were the take-home points for the day?
• Many museums across the UK and abroad contain fascinating specimens from southwest Britain
• You can explore the collections of the southwest from the comfort of your own home. The British Geological Survey has online catalogues of the rocks, fossils and minerals transferred from the Royal Geological Society of Cornwall
• The geology of southwest Britain has influenced so many lives. People have been collecting from the southwest for centuries and many continue to do so today
