If you would like to visit a working quarry with a geological society (such as the Stamford and District Geological Group), you will have a much higher chance of finding fossils and much better specimens. We always caution members when sites are potentially not suitable for younger children, or where admission for any child is not possible (e.g. a working quarry).
We carry out risk assessments at all locations we visit and clear directions are given to all members as to how to get there. Details will be found on our website or Facebook page
To comply with the Data Protection Act, the personal information in the above membeship forms will be used by Stamford & District Geological Society to communicate with members.. It will not be disclosed to third parties and on becoming a member, you agree to your details being held by Stamford & District Geological Society.

At Tinwell Village Hall near Stamford @ 7.30pm on Wednesday the 13th of March 2019. Free admission for members of the SDGS and £3 for non_members. You can apply for membership to the society on the night.
So Id thought you would like to see a small array of fossils from my collection collected from around the Isle of Wight. With contributions kindly given as to their I.D.S from Jack Wonfor and Theo Vickers from the very informative @WightCoastFossils.
It’s great to know that there are people out there willing to give some of their time up to help understand the fossil fauna around the Isle of Wight.
It is valuable (research) information that is freely given out and makes fossil collecting a lot more worthwhile when trying to understand what you have found and holding in your hand.
And perhaps something that hasn’t been seen or handled a very long time indeed!
The “quoted” descriptions for the fossil photos will be from members of the @WightCoastFossil to the best of their abilities.
If you can take any of the information provided here with you, and proves useful next time you visit the Isle of Wight….then that would be an achievement in itself.
“This fossil photographed at different angles below appears more likely to be a fragment of fish bone as opposed to turtle based on the ‘flaky’ texture and the preservation of the specimen. It’s most probably a bowfin (amiid) as they are the most common large fish found at the site.”
I really like the sturdiness of the Bothriodon sp tooth (pictures below) when held in the hand from the Isle of Wight, Lower Hamstead Beds in Bouldnor, and wanted to know are these indents possible wear facets (indicated by the blue arrow). But before I can really ask that question with confidence, I thought it would be best to ask Theo Vickers from @White Coast Fossils first which end of the tooth the root and which end of the tooth the tip is.
I’ve quoted Theo’s very informative reply below:
“The tip is where you have the small area of enamel, as visible in the third image down. The area you have highlighted would be at the very base of the root so would be unlikely to be a wear facet. Many vertebrate specimens from the upper Hamstead Member exhibit a fair degree of wear and abrasion from pre-depositional transport on the coastal plain and also have signs of mollusc boring, which may account for the marks you’re seeing on the root.”
Various photos of another Bouldnor fossil find below that I found from the Hamstead Beds and described as…
“A relatively uncommon partial mandible of a large amiid (bowfin).”
….And a smaller partial amiid (bowfin) jaw (photos below) which tend to be very common.
For those of you who know Stamford and District Geological Society member Richard Forrest and his canny habit of not to be beaten by the fossil in front of him when it comes to prepping.
Well here is another example of one his tried and tested techniques on the sea urchin a Clypeus ploti.
Field Secretary Kenny Nye has been very busy over the past couple of months fine tuning the society’s field trip calendar for 2019. With some potential dates pencilled in for Ketton Quarry so perhaps we all can try Richards technique quoted below 😊
“If like me you collect fossils, you may have been struck by the way in which natural weathering can ‘prepare’ fossils rather better than standard preparation methods. This intrigues me, and has made me wonder if this can be replicated in some way. My best guess is that the natural process is a combination of freeze/thaw cycles and mildly acid washes from rain. So this is my kitchen sink (rather literally!) experiment. I’ve used two echinoids of the genus Clypeus collected from the Blisworth Sandstone from Ketton as test subjects. These fossils are relatively common, and no great loss if the experiment destroys them. Both were partly covered by hard matrix when found. I first soaked the specimen in water made slightly acidic by a slug of vinegar. After leaving it for a couple of hours, I drained away the water and put it in the freezer at a temperature of approximately -20˚C. After a few hours, out of the freezer. To start with I then poured warm water over specimen. After the ﬁrst few cycles I used boiling water. The initial effect of this was to spall small fragments of matrix off the surface.”
“The process seemed to work pretty well. I started a second echinoid when part-way through the process making use of what I had learned at the time. The freeze/thaw cycles spall off small fragments of matrix as a the hot water hits the specimen and expose ﬁne surface detail which other methods may not reveal. Larger, hard chunks of matrix are softened and can be scraped off more easily. This is a very limited experiment as only one type of fossil from one Formation was used. Many fossils are affected by water, and obviously cannot be prepared in this way. Fragile specimens may disintegrate under the thermal stresses created. But then, as every experienced preparator knows, each fossil is different, and needs different preparation methods. Specimen 1 has been given to my grandson Otis who was born on the day I found it – you need to start them young! The following images are of the second specimen and show the fine surface detail the process has revealed.”
“Photographs taken on Olympus TG-4 using integral focus stacking and LED light guide.”
So these are the ‘pound stones’ William Smith was finding in the story of the first geological map – The Map That Changed the World’. It’s a nice little historical footnote for these great specimens.
An article titled “Fulletby brickyard – a classic locality in the Upper Jurassic Kimmeridge Clay Formation in Lincolnshire” written for the Deposits Magazine by Stamford and District Geological Society member John Green is now available at the link below.
I sent some photos of this thought-provoking fossil pictured below I found from the Bembridge marls in Hamstead on the Isle of Wight to Alan Morton. Alan runs the very informative website http://www.dmap.co.uk/fossils/index.htm which has a Collection of Eocene and Oligocene Fossils.
This was his much needed reply quoted below.
“Thanks for sending those images.
I must start by saying that I do not know what these objects are. I come across similar objects frequently whilst sorting through samples of the Bembridge Marls, looking for rare species of mollusc. I put these bony objects aside, hoping that one day I shall be in contact with someone who can shed more light on them. There is one of my specimens of a similar object to yours on the website http://www.dmap.co.uk/fossils/index.htm and pictured below as “Unidentified 3.4mm” placed between the reptile remains and mammal remains in the table of images.
I think that the only thing we can really rule out is mammal. You may be right in thinking they are fish, but fish bones are usually rather thin and laminated or ‘flaky’, whereas these objects seem rather more solid, and usually very black, smooth and shiny on their surfaces. I don’t think we can at this stage rule out reptile, or even amphibian. I do wonder whether they might be some sort of dermal bony protective plates of some sort. They don’t look right to me for dental plates.
Anyway, I’d love to know what they are, and I would then put some more examples on the website to help others with their ids, so if you are able to make any further progress with them, do let me know.
A couple of months ago while conducting the pyrite survey with other volunteers at the Peterborough Museum, we found a note in a box of Pliosaur fossils saying about a report on the find in the Peterborough advertiser newspaper and the date 29th of October 1926.
So, with further research from one of the Peterborough volunteers “Ivor Crowson” who is also an honorary member of the Stamford and District Geological Society, went onto finding in the archives at the Peterborough Central Library on Broadway this associated newspaper article. Quoted below, as the quality of the archive including the photograph is as found in the archives.
“Is This a PLIOSAURUS FEROX”
“THIS CONSIDERABLY-FLATTENED SURIAN lying in the Oxford Clay at Messrs Eastwoods Yardat Fletton, is arousing considerable attention because if it is the PliosaurusFerox- Fierce variety – it is somewhat rare. The inordinate length of the flappers is noteworthy. The head is gone, but probably it is amongst Mr.Phillips collection in the Peterborough Museum, which was secured by the Museum Society. At any rate, if the Eastwood fossil finds a home there, no difficulty will be experienced in completing the beastie. It was originally an inhabitant of the sea, which was over Fletton in its day, millions of years ago. It was probably chocked to death a tremendous flood bringing tons of mud down thechannel, which emptied into the shallow Oxford Clay sea. It may have come toits end fighting with another of its species, but it was covered with mud before it had time to decay and has thus been preserved. We are now making bricks of that mud deposit!”
I then went onto conduct my own research and established exactly where the Eastwoods Yard brickworks at Fletton 1B(1) indicated in the photo below, used to be in Peterborough in 1926.
The above additional information helps to tell the story of this very important find. And just goes to show with further research for finds such as these by museum volunteers, will always help give provenance when none is available at the time.
When you read and “quoted” below from the very informative Oxford University Museum Natural History website.
“Oxford University Museum of Natural History was founded in 1860, and today it holds an internationally-significant collection of natural history specimens and archives. Housed in a stunning neo-Gothic building inspired by the Pre-Raphaelites, the Museum is home to a lively programme of research, teaching and public events.”
You know its going to be a great day.
The architecture of this stunning building really comes to life with full sunlight beaming down for the mid-morning arrival of members of the Stamford and District Geological Society. As we were treated to an organised behind the scenes tour of palaeontology, guided by Dr Hilary Ketchum Collections Manager, Palaeontology.
With kind permission from the OUMNH we can show you some pictures from the day below.
Hilary talking to us about some of the historic fossils housed at the museum.
Stunning Ichthyosaur and plesiosaur display cases.
And a real treat to see a marine crocodile found in Eye, Peterborough.
And of course seeing the newly found plesiosaur “Eve” also from Peterborough.
Ending the guided tour with a wonderful look at some of the many thousands of vertebrate fossils collected from the past and present. To which I can assure you was a real eye opener for our younger members.
We shall hopefully organise another trip to the OUMNH next year.
One of the things that makes mammals special is our diverse forelimbs -- bat wings, whale flippers, gibbon arms, and cheetah legs have evolved to do different, specialized tasks. Scientists wanted to see where this mammalian trait started evolving, so they examined fossils from early mammal relatives to see when the upper arm bones started […]
A scientific study describes for the first time the submarine cartography of a high-latitude system in the IBIS channel, which covers tens of kilometers in the northern western area of the Barents Sea, in the Arctic Ocean. This channel is one of the few submarine valleys in polar latitudes that kept its geological architecture during […]
For the first time, researchers have simulated the process of surface roughness creation. This is a step forward in understanding the emergence of fractal characteristic of rough surfaces on many scales ranging from atomic to geological scales. The perspectives of their findings are far reaching. Controlling surface roughness is essential to the performance and durability […]
Cannot wait for #NatSCA2019 it's an ace line up of talks, the tours are around some of my favourite places, and well its 🇮🇪Dublin🇪🇺, just simply one of the best for culture, lovely people and good drinks! https://t.co/3ReQ2H3pRO
