The splendid website London Pavement Geology (www.londonpavementgeology.co.uk) has been extended across the UK and tells you where to find treasures hidden in plain sight. Here are some London fossils from the LSE and Somerset House.

Now, a study from University of East London looks at ways to restore some of the "sponginess" the city has lost, protecting vulnerable homes & businesses. share.google/2iw1I5qDkKA7...

Once, marshes in East London could absorb some flood water. We've built over these with a sea of concrete, losing the 'sponginess' to absorb intense climate-driven rain. Sewers built for an era of lower rainfall can be overwhelmed, contaminating flood waters. 🧵 1 share.google/9GzrOUZUubep...

A new Site of Geological Interest (SGI) for London; the spectacular Saran boulder in Lampton Park, Hounslow londongeopartnership.org.uk/wp/wp-conten... #londongeology

Thanks to Ben Lerwill for a lovely article on my #urbangeology walks in today’s @theguardian.com www.theguardian.com/travel/2026/...

You can learn more about the excavation findings at the Curtain Theatre from this Museum of London Archaeology blog post: www.mola.org.uk/discoveries/... The team shares the remarkable discovery that the stage was 14 metres long (directly related to Blyth’s argument about R&J's fight choreo).

The latest edition to our Greater London Authority #geosites is Gunnersbury Park in Hounslow. The geology is mainly Langley Silt Member, Maidenhead Formation (Pleistocene-Holocene) and parts of the current park were once brick pits.

An urban geomooch around the city of London today. Paid a visit to Irongate House clad in South African Parys Gneiss with black veins of pseudotachylite - glass formed through meteorite impact - quarried in the Vredefort Structure. Extraordinary #urbangeology. See ruthsiddall.co.uk/Walks/Ironga...

We see your Humble Jumble Lane and raise you Crack-brain-court and New Martin Street a.k.a. Shall-I-go-naked-street! These are from Whitechapel, London, in the early 1700s. Does anyone have any more stupendous street names, from #OnePlaceStudies or elsewhere, to share on #OnePlaceWednesday?

As a proud resident of Wilcumstowe, I love this marvellous map of Saxon London by Matt Brown londonist.substack.com/p/mapping-an...

Anyone looking for the full map or wondering who made it, it’s the work of Matt Brown and it’s here. open.substack.com/pub/londonis...

#Urbangeology Christmas Quiz! Can you guess where I am in the UK from the stone below? (I know there are a few of you who will get this immediately!)

6.30pm Monday 8 Dec online What can zooarchaeology tell us about the lives of the dogs & bears involved in animal-baiting on Bankside and beyond? A catch-up link will be made available to those who have bought a ticket but can't attend on the day.

We have a hew information sign in Bermondsey! Designed and organised by our members and artists @gaildickerson.bsky.social and @deemcleanart.bsky.social and located near the Tideway excavations at Chambers Wharf, it illustrates geology and archaeology from this reach of the Thames #londongeology

I’ve written a piece on the curious lack of media and political interest in the issues faced by our national @britishlibrary.bsky.social. This is strange given we live in a world where ideas, knowledge and research are a long-term source of innovation and insight www.cityam.com/the-british-...

Why are all these chalk boulders on the foreshore of the River Thames? They are derived from barge beds - platforms constructed from chalk blocks onto which barges could beach. You can often see remains of barge beds ie at Battersea #londongeology #urbangeology #Thames

#FossilFriday at #SVP2025 today! Emma Bernard will be talking about dating the amazing @nhm-london.bsky.social chalk fish collections at 09:30 in Hall 4. Then check out posters by Twitchett/Underwood and Kaia Spence on new #chalk sharks & coelacanth size in Poster Session III, Hall 3 (4:30 - 6:30).

Unravel the curious case of the 1725 London Excursion — a field report that seems to have been written 200 years before its time. Join Nina Morgan as she pieces together clues to uncover the real story behind the publication 🕵️‍♀ geoscientist.online/sections/fea... #geoscience #geology #history

Great to be back in the wonderful Yorkshire Museum today for a day in women in geology organised by the Yorkshire Geological Society.

A wet day out to look at the Pulhamite outcrops in Battersea Park. These are man made ‘outcrops’ constructed in the 1870s #urbangeology #londongeology

Did you go to the @geolassoc.bsky.social Festival of Geology this weekend? Please do share your photos of walks, talks and other events! #festivalofgeology #fog

This was a lot of fun to write for the BBC - the joys of 'urban geology': fossil-hunting and more in the buildings of central London with @pavementgeology.bsky.social. She even showed me a possible dinosaur bone! #urbangeology www.bbc.com/future/artic...

Many thanks to @richardfisher.bsky.social for this lovely article on my #urbangeology rambles! www.bbc.co.uk/future/artic...

My final #urbangeology walk for this year will take place on 4 October. Reservations and more information on #LondonWalks website at www.walks.com/our-walks/th.... Hope to see you there, this is my favourite walk!

Some photos from yesterday’s guided walk to Hainault Forest Park #londongeology #hainaultforest #walklondon

Another busy weekend! LGP’s stand at Abbey Woods Woodland Festival. Open until 4 pm, come and learn about #londongeology

Come and visit our stall at the Highgate Wood Community Heritage Day today and learn about the geology of the woods and London. More information at www.cityoflondon.gov.uk/events/commu... #londongeology #highgatewoods

Very inspiring indeed!

A couple of photos from our walk today for #inspirallondon led by myself & fellow LGP member @gaildickerson.bsky.social. The walk - Rivers, Reservoirs, Ice &Sea - looked at the geology and colours in the landscape in East London. We walked from Forest Gate E7 to Wood Street E17 #londongeology

Next Saturday I’m doing a walk with #InspiralLondon and artist @gaildickerson.bsky.social; Rivers, Reservoirs, Ice and Sea. More info and booking details in the link below www.inspirallondon.com/event/rivers...

Our colleagues at the Geologists' Association club for junior geologists: @rockwatch.bsky.social currently have a vacancy for a volunteer Fieldtrip Manager. If you are interested helping to inspire the next generation of junior geologists email [email protected] for more details.

There are a surprising number of fossil trees hidden in London and the small fossil forest at Regent’s Park is one of our London Sites of Geological Interest (#SGI). Check them out in the list below

Paternoster Square was once a really nice piazza in the City of London. Today it’s full of clutter, sheds and poor quality public art #walklondon

The London Museum recently asked me to write about clay pipes for their online blog linked to their exhibition 'Secrets of the Thames'. Read about how I first started pipe-larking, and see some of my favourite photos: www.londonmuseum.org.uk/blog/mudlarking-clay-tobacco-pipes-thames-foreshore

I recently read Smith & Martill’s paper on pterosaur fossils in Portland Stone. Here’s a bone fragment I found in PS in London and its porosity + thin outer layer have always made me wonder if it could be a pterosaur. Any ideas @nataliajagielska.bsky.social & other palaeo bone folk? #urbangeology

On Saturday! A few places left for an #urbangeology walk in Regent’s Place and Fitzrovia, 14 June from 2-4 pm. This walk is in collaboration with the exhibition ‘The Geological Unconscious’ at Hypha Gallery, Regent’s Place. Booking www.eventbrite.co.uk/e/urban-geol...

Portland Stone is used for buildings all over London. You can spot these fossils on London’s buildings #urbangeology #portlandstone
