Urban fossil hunting fun from a 19th century wall built 1822-66 in Ledbury, Herefordshire. These brachiopod shells and crinoid stems, and colonial coral, are preserved remains of animals that lived in a warm shallow sea about 430 million years ago. I don't know which quarry these ashlar blocks originated from but they're Much Wenlock Limestone. They can be found on the Barrett Browning Institute facing The Homend, named for poet Elizabeth Barrett Browning, which is appropriate as I was there for the literary festival. There are also crinoid stems in the cobbles paving Church Lane.

Beautiful bark imprints in this coarse grained sandstone in the park.

Me, nodding sagely: This 680,000,000 year old granite has been through some things and is what experts refer to as "altered", which is what happens when two continents bump together and make mountain babies.

(These three rough blocks are from a rubble masonry wall. They appear to be Precambrian granite, and perhaps diorite, around 680-650 million years old, later altered in the Variscan orogeny about 290 million years ago. The alteration looks mylonitic but other features are also present.)

Beautiful fossiliferous tiles at the Deutsches Bergbau Museum in Bochum, Germany.

Nice choice of rock for this building front. Maybe some kind of sodalite nepheline syenite, but I'm not sure?!

@urbangeology Yey! You're here!!

Let me greet you with this glorious polished cladding a wall in Nottingham. 🙂

You can lose yourself looking at what you could swear is 3d detail (Reader, it isn't!)

(For folk who are interested, serpentinites are rocks that form from changes to certain existing igneous rocks. Hydrothermal fluids that percolate through them can deposit minerals that solidify in in a snakeskin-like pattern - hence the name.)

This side project started on the bird app pre-covid, but turned out be pretty fun and useful during home office, lockdowns and quarantine and got more attention than I imagined. 😁 Just keep your eyes open and look out for geology around you, no matter if at home or in the city. Tiles, windowsills, countertops etc. made out of beautiful and fossils - share your findings and use the hashtag .

There are opportunities to engage public in topics and issues by looking at the urban environment with an lens. One intro topic that grabs peoples attention is occurrence of sidewalk “fossils”. Geology we walk on every day is worth talking about.

Did you know? There are two footprints of a Wolf in front of the Museum of Natural History in - two right paw prints of a Wolf added by a curator when the concrete was wet.
