Insect Fossil Discovery at Museum of Somerset
More than 2,000 insect fossils dating to the Jurassic period have been found at the Museum of Somerset after being forgotten for more than 90 years.
Geologist Charles Moore excavated them in the 1800s, but they were put in storage in 1915 and forgotten about. They were rediscovered at the museum in Taunton as part of a project to restore Moore’s entire fossil collection.
The missing specimens were found by the Bath Royal Literary and Scientific Institution (BRLSI). The BRLSI received £62,000 in funding from the Esmee Fairbairn Foundation to carry out a three-year research and restoration programme of Moore’s collection.

This has included restoring marine fossils, bringing in scientists from Bristol University to research them and locating the missing part of Moore’s collection.
Moore excavated thousands of marine and insect fossils, mainly from Strawberry Bank, a working quarry near Ilminster, as well as from sites around the South West.
The marine fossils from Strawberry Bank are regarded as rare because of the level of detail in the muscles, guts, traces of skin and eye colour of the fish specimens. The researchers have also traced the location of the insect fossils which Moore wrote about in his studies.
Matt Williams, the collections manager at BRLSI who is overseeing the project, said: "Their presence at the museum was first noted in the 1980s but no-one had really pursued it. Charles Moore had died in 1881 and in 1915 most of his collection of more than 4,000 fossils was bought by BRLSI.
"But part of his collection was given away to the then Somerset Archaeological and Natural History Society and their collection is now housed by the Museum of Somerset and I had heard amongst those specimens might be some from Strawberry Bank.
"These packages haven’t been unwrapped since 1915 and some are in wrappings dating back to 1867 so it’s quite exciting to unwrap them for the first time – and amongst them I have been discovering unknown Strawberry Bank specimens."
So far they have found winged insects, such as beetles and cockroaches, but are in the process of cataloguing all the specimens before further research can be carried out on them.
As part of the programme, Bristol City Museum preparator Lori Barber also began work last March to restore some of the marine fossils. So far she has restored 24 of 100 of the fossils which have been chosen for further research by using a special instrument called a micro jack and works in a similar way to a pneumatic road drill but has a tungsten carbide needle. It is used to chip away the rock from the fossils without damaging the fossil itself.
"When the fossils were originally discovered, the chap who discovered them, Charles Moore, would have struck them with a hammer and then done some very rough work with a chisel to expose the fossil," said Mr Williams.
Prof Mike Benton, from Bristol University, has been researching the Strawberry Bank marine fossils.
"Ichthyosaurs are a group of swimming predatory marine reptiles and he has discovered there were two rather than one species of ichthyosaurs living in Strawberry Bank," said Mr Williams.
"The papers suggests the site may have represented a shallow place where the ichthyosaurs reared their young.
"Ichthyosaurs gave birth to live young and of course a shallow sea is more protective for juvenile specimens. All the ichthyosaurs from that locality are juveniles."
Prof Benton expects to release more details of his findings later in the year.

Charles Moore (1815 – 1881)
- Born in Ilminster, Somerset, he left school at 14 to follow in his father’s footsteps as a bookseller in the town
- His marriage to Eliza Maria Deare made him financially independent and thus able to focus on his geology and fossil collecting
- He established the presence of Rheatic rocks in the UK previously only known to exist in Germany – they represented a period between Triassic and the Jurassic period
- Had 3,000 tonnes of rock from Holwell quarry carted to his house which he sorted through by hand for fossils
- Wrote over 50 scientific papers and was made a fellow of the Geological Society
