23 September 1835: Mary Anning writes to Cambridge geologist Adam Sedgwick in Dent, Yorkshire, anxious to hear that the £50 ichthyosaur she sent him earlier in the month, ℅ the Geological Society, met with his approval. It clearly did and it is still in the collections @sedgwickmuseum.bsky.social
Portrait of Mary Anning wearing a green cloak and a straw bonnet tied with a red ribbon. Portrait of a youngish Adam Sedgwick in a dark jacket and academic gown. Extract of a letter from Mary Anning to Adam Sedgwick:  [I] 'trust you will be gratified with the Ichthyosaurus when you see it - I directed it to Professor Sedgwick Geological Society Somerset House'. The ichthyosaur skeleton referred to in Mary Anning's letter, purchased by Adam Sedgwick and presented by him to the Cambridge University geological collection. Its head with its long, pointed jaws to the right and tail to the left and well-preserved body and paddles. The mount has a painted label 'ICHTHYOSAURUS Communis Lias. Lyme Regis. Presented by Profr. SEDGWICK.'

Today’s #MineralMonday is Biotite.
 
Biotite is a silicate mineral which is usually found in igneous or metamorphic rocks and commonly black or dark green in colour. It is a mica mineral which gives it the characteristic property of fracturing into fine, flexible sheets.
 
#Biotite #SedgwickMuseum
An igneous rock with a large biotite crystal held in the hand of a Sedgwick Museum staff member. The crystal is so large, it is all you can see from this angle. It is green-back in colour but appears black in the image. Its sheet- like texture can be seen on its surface. The same rock held at an angle that allows you to see other crystals in it. The other crystals are pink and white I colour. Another angle shows the sheet like texture of biotite from the side. The thin sheet layers can be seen clearly.

This majestic fossil shell is a #StaffFavourite. 🌊🐚
 
Commonly known as a scallop, this shell belongs to the Pectinidae family.

This fossil is approximately 3 million years old but Pecten maximus can still be found along the English coast today.
 
#Pectinidae #Bivalve #SedgwickMuseum
Pecten maximum held up outside the Museum with the building in the background. The fossil shell is the width of two of the staff member’s hands holding it up. It is an orangy-red colour. There are beautiful ridges in the shell. A closer look at the fossil shell. A few marks can be seen on the shell which look like they were barnacles.

We had a wonderful time celebrating Pride Month on Wednesday with everyone who attended our late opening, ‘Rock Up and Chill'. 🏳️‍🌈🏳️‍⚧️🦖

Thank you to everyone who attended the event and contributed to our collaborative artwork.

#PrideMonth #RockUpAndChill #QueerHistory #SedgwickMuseum #EarthSciences
A window on which is our collaborative artwork. There are black letters stating ‘Everybody’s Welcome’ around them are a collage of coloured acetate paper. Some is different colours others have rocks under a microscope printed on them. Visitors sitting and making their contribution to the collaborative artwork. There is microscopes through which you can look at minerals under a microscope. These were used as inspiration for the art.

How old are the oldest known fossils?
 
This fossil is called a stromatolite which are the most ancient known fossils dating back approximately 3.5 billion years. Stromatolites were among the earliest lifeforms on our planet.
 
#Stromatolites #SedgwickMuseum #EarthSciences #EarthHistory
A cut and polished stromatolite fossil held up in front of the Museum building. A close up of the stromatolite fossil showing the layers and domes formed within. The layers are no more than a mm thick.

Want to find out more about trilobites and other ancient animals that evolved long before the dinosaurs? Drop in to our family, half-term holiday event on Tuesday 27th May and Friday 30th May from 10am – 1pm.
sedgwickmuseum.bsky.social
You can meet with Lara Uttinger, a scientist in the Department of Earth Sciences, to chat about long extinct animals and find evidence of them in the Museum. You will also get the chance to explore real fossils and use them to create your own trilobite replica fossil to take home.

Do you know how many species of trilobites have roamed the Earth? 🌍
 
Over their 250 million-year existence, there were over 20,000 different species! During their long history, they diversified into many species with different sizes, habitats, and anatomy.

“Minerals are from the Earth and the Earth belongs to everyone. So everyone should be welcome in society.” – Y10 work experience student, 2022
Two pairs of hands holding a variety of minerals which are different colours. On the left, 5 minerals which are blue, pink and white are held in the same configuration as the transgender flag. On the right, 4 minerals which are yellow, white, purple and black are held in the same configuration as the non-binary flag. Underneath the hands is green foliage acting as a backdrop.

This toothy grin could once have been found in parts of England 35 million years ago. 🐊
 
This fascinating fossil is an extinct relative of the alligator and is thought to have enjoyed a similar diet of fish, mammals and birds. Its generic name is Diplocynodon.

A photograph of a skull belonging to an alligatoroid with the generic name of Dyplocynodon. The skull is sitting in a museum cabinet with other specimens on the shelf just below. The Diplocynodon skull photographed at a closer angle to see the teeth in more detail. Other specimens in the cabinet can be seen in the background.

Did you know bivalve fossils can provide information about past environments? 🌊

Michael and Julia, from the University of Cologne, have been studying fossil bivalves in our collection to understand if bivalve morphology is linked to the environmental conditions in which they lived.
 
#FossilFriday
A photograph taken in the Collections Research Centre in our Second Palaeontology Store. In the foreground is a drawer containing bivalves from the Jurassic. Behind the drawer is Julia photographing bivalves with Michael sitting just behind her. Cabinets full of drawers can be seen around them. A close up of the drawer that Julia and Michael were working on when the photograph was taken. Each specimen is sitting in a small cardboard tray with a label in. The fossils are all creamy-white in colour.

Did you know this fossil is commonly referred to as a ‘Devil’s toenail’?

Gryphaea got the name ‘Devil’s toenail’ from British folklore. They were associated with the Devil due to their characteristic large, thick, curved shells that resemble toenails.
 
#MolluscMonday #SedgwickMuseum #EarthSciences
A Gryphaea fossil held by a Sedgwick Museum staff member. The fossil is positioned standing up so we can see the two valves showing the characteristic curved thick walls. A Gryphaea fossil held by a Sedgwick Museum staff member. The fossil is positioned side on so we can see the curve of the shell which is very reminiscent of a toenail.

What kind of labour gets recognised, when we think about minerals in museums?
Who do we involve in recovering and telling their stories?

Helpful prompts from @ellietheelement.bsky.social in @originalgcg.bsky.social EDI symposium this morning, relevant to our thinking @sedgwickmuseum.bsky.social

These fascinating fossils look like intricate works of art. 🖼️
 
Even though they have been entombed in stone for over 150 million years, these delicate creatures look as if they are still swaying with the currents of the sea. 🌊

Did you know that, under the right conditions, rocks can bend?
 
For today’s #TectonicTuesday, here are some folds in banded amphibolite found in Norway.

Studying the geometry of folds can help us understand the deformation history of rocks.
 
#TectonicTuesday #SedgwickMuseum #EarthSciences
A folded amphibolite being held up in front of a wall of 13 other rocks. The amphibolite is grey with darker grey bands in it. The bands are folded in an undulating way. The rock wall behind is brown in colour and there is an array of rocks displayed. Some are folded and others are fractured.

Our collection is regularly used by an array of researchers. 🔬

Here is Kaia, a Masters student at UCL, measuring a fossil coelacanth from the Cretaceous which was found in Maidstone, Kent. Kaia studied a variety of bony fish to inform her research. 🐟
