You wouldn't want this star on your Christmas tree! Starfish, like crinoids, usually fall apart soon after death. This Middle Jurassic specimen is beautifully preserved suggesting it was buried alive! On that thought, Merry Christmas everyone! #FossilFriday 📍 North York Moors 🏛️ Manchester Museum

Stick your neck out and have a guess at which animal this is! These bones were found in Dowkerbottom Cave, near Arncliffe in the Yorkshire Dales. This animal still exists in the UK, however you'll not find it roaming wild in the Dales anymore. 🏛️ Leeds Discovery Centre #FossilFriday

Ever been fossil hunting around Malton and Pickering? Chances are you'll have found one of these. This is Pseudomelania, a high spired gastropod that lived in the shallow carbonate lagoons of the Late Jurassic - a time when Yorkshire was altogether more tropical! #FossilFriday 🏛️ Yorkshire Museum

Since yesterday was Lancashire Day, here's a Lancastrian #FossilFriday post! This may look like an ammonite, but this is Gastrioceras, a chunky goniatite. Goniatites are often found crushed in mudstone, however this one is beautifully pyritized and preserved in 3D. 🏛️ Leeds Museums and Galleries

We had an excellent time yesterday at Otley Science Festival, talking to visitors about Pholiderpeton - Bradford's Carboniferous tetrapod! Lots of people successfully pieced back together the jumbled up skeleton of this incredible fossil and explored a range of other fossils from the Coal Swamps!

A busy couple of days for Fossils in t' Hills. This evening we'll be discussing Carboniferous fossil trees with GeoLancashire from 19:15 (geolancashire.org.uk/events/) Then tomorrow we're taking our Pholiderpeton puzzles to Otley Science Festival! #FossilFriday

Friday 14th November, 19:15 at Hanson UK’s Ribblesdale cement works in Clitheroe. Come along to find out about the undisputed giants of the Carboniferous and the forgotten fossil forests of the North West! geolancashire.org.uk/events/

We're back at the Otley Science Festival! This year, we're unjumbling the bones of Pholiderpeton, Bradford's Carboniferous swamp monster! Come along on Saturday 15th from 10:00 to the Otley Courthouse and see if you can make head or tail out of these bones! #FossilFriday 🏛️ Cliffe Castle 📍 Bradford

A spooky fossil for Halloween! The Carboniferous swamps of the north of England were full of creepy crawlies... This is one of them, a spider-like creature called Mesotarbus. 📍 Westhoughton 🏛️ Manchester Museum 📷 GB3D Fossils #FossilFriday

We're heading back to Cliffe Castle! Join us on October 28th from 11:00 for a day of Carboniferous activities. With your help we'll be reconstructing a coal forest and unjumbling the bones of Pholiderpeton. Don't forget to bring along your own fossils for identification! #FossilFriday

Autumn has descended on Yorkshire this week, the leaves have started to fall. Most leaves rot away leaving nothing behind, but not this one! The leaf became encased in tufa, a carbonate mineral formed by springs, to leave a perfect impression. #FossilFriday 🏛️ Craven Museum

We post a lot about the Carboniferous swamp plant fossils - and for good reason, as these are incredibly important to both human history and science in Northern England! These swamps were also home to a range of other creatures, including lots of fish and sharks... #FossilFriday 🏛️ Gallery Oldham

Tiny fossil cogs? Not quite, these are single segments (ossicles) of a crinoid stem. In life, soft tissues would have run through the central hole. The radial groves and ridges would have prevented the sections of the stem from twisting in currents. 📍 Wensleydale #FossilFriday

Some fossils leave an impression on you - or on the rock! We spotted this impression of a spiriferid brachiopod on our way up Pen-y-ghent over summer. If you look carefully you can also see a crinoid ossicle. We're hoping for the rain to stop so we can get back out into the hills! #FossilFriday

Even in poor visibility on top of Ingleborough, we still found fossil plants! This is in the Millstone Grit at the very topmost part of the peak. #FossilFriday

Today's #FossilFriday post is a Sea Monster and some Seashells... Why? Because tomorrow afternoon we are back at the fantastic Land of Iron Museum to take people on a tour of the Jurassic ocean! 🐬 The ichthyosaur Temnodontosaurus zetlandicus from Loftus 🐚 A shell-bed of the bivalve Bositra

Some fossils really stand out from the rock. We spotted this vibrant solitary coral in the Yoredale series of rocks near Pateley Bridge. #FossilFriday

This trilobite has a very cute name - Dindymene - at less than 1cm across it's more like Diddymene! At 440 million years old this fossil is from some of the oldest rocks in the Yorkshire Dales, and appears to have been slightly distorted over the years... #FossilFriday 🏛️ Sedgwick 📷 GB3D Fossils

Picture in your mind a shark tooth... We bet this isnt the shape you were thinking of! The shark Ptychodus had a 'pavement' of these strange teeth for crushing hard-shelled prey. Ptychodus fossils have been found all over the world, including from Hessle near Hull. 🏛️ Sedgwick Museum #FossilFriday

Crinoidal limestone – limestone made of crinoids – what more needs saying? #FossilFriday 📍 Hebden, near Grassington

For #YorkshireDay and #FossiFriday we're celebrating the giant ammonites of Yorkshire! From the foreshores of Redcar with their monstrous Arietites, to the oolite of Malton with its mighty Perisphinctes - and beyond! Post your giant Yorkshire ammonite finds in the comments! 🏛️ Whitby Museum

Lurking at the bottom of the limestone in the dales is a rather impressive conglomerate – a rock made up of pebbles of other rocks. This piece was pulled out of a cave by divers and contains a few gastropods in amongst the pebbles – can you spot them? #FossilFriday 📍 Austwick

This weekend is Lancaster Dino Fest! But it's not just dinosaurs that had scales! Come along tomorrow to St Nic's Arcade Lancaster to find out about the ancient scaly inhabitants of Lancashire and help us build a Carboniferous coal swamp! 🏛️ Manchester Museum #Fossil Friday

With Lancaster Dino Fest just around the corner, we're highlighting fossils from Lancashire! Much of Lancashire is underlain by Carboniferous rocks, this lovely fern was found in one of the many coal mines from the area. #FossilFriday 🏛️ British Geological Survey 📷 GB3D Type Fossils

Digging a railway in N England in the 1800s usually resulted in finding huge fossil trees! These pair of Sigillaria were unearthed in 1837 in the outskirts of Manchester. On July 12th we're exploring the fossil trees of the NW at Lancaster Dino Fest, come along to find out more! #FossilFriday

With this hot weather it seems appropriate to post about the tropical inhabitants of the Jurassic Seas of Yorkshire. This little chlamys (a scallop) was found in a stream near Kirkbymoorside, although during the Jurassic it would have been a shallow tropical sea. #FossilFriday

Heading to Redcar tomorrow for the Fossil Walks with the Yorkshire Fossils Festival team? Before you head down to the beach, cast your eyes to the pavements. The promenade along the front is paved with some incredible Carboniferous fossils in black limestone. #FossilFriday

This lovely fossil is a sapling of a giant plant similar to those in Bradford's parks. It's photographed upside down to clearly show the 4 branching roots that all of these plants have - unfortunately the one closest has broken off and is missing. #FossilFriday 🏛️ Gallery Oldham

Some creatures are windows into the past - others are just windows... This fossil is a fenestrate bryozoan. The fenestrate part of the name derives from the Latin for window, and refers to the grid-like skeleton of these filter-feeding colonial organisms. 📍 Thorpe 🏛️ Gallery Oldham #FossilFriday

Last weekend Team Fossils in t'Hills (and friend) went on an adventure under the hills! We were thrilled to once again join Bradford Pothole Club at their winch meet at Gaping Gill.

Heading out to a park this #FossilFriday? Be sure to visit Horton Park in Bradford, where you can see one of three huge fossil trees! These Carboniferous giants were excavated from Clayton in the late 19th Century and placed on public display to "inspire future generations of geologists".

Looks like we're in for more glorious weather here in Yorkshire! With extremely low water levels it's a great time to head out to a stream to see what you can find! We recently spotted this lovely little Siphonodendron amongst the cobbles in a dry stream near Horton in Ribblesdale. #FossilFriday

Some beds are so distinctive we can use them to work out where we are in the sequence. One such bed is the Clayton Shell Bed. Found in the Harrogate area this shell bed contains a wealth of marine species including these beautiful spiriferid brachiopods. #FossilFriday 🏛️@leedsmuseums.bsky.social

Anyone for fossils and chips? After work we had a takeaway sitting by the riverbank, followed by a quick look along the river beach - where we found this lovely little Stigmaria! 📍 Gargrave #Yorkshire #YorkshireFossils #ukfossils #fossilplant #carboniferous #geology #gargrave #FossilFriday

Not long until the Geology Rocks event @ncmme.bsky.social Come along to meet Edestus - Huddersfield's mysterious ancient inhabitant! How will you interpret this fossils? What was its function? Come by our stall to create your own reconstruction! #FossilFriday 🏛️@britgeosurvey.bsky.social 📷 GB3D

It's been so warm in Yorkshire this week you could be forgiven for thinking you were in the Carboniferous, when tropical corals like this Lithostrotion were alive... ...Ok, so it's not really been tropical here this week, but it's been beautiful weather! #FossilFriday 🏛️ @galleryoldham.bsky.social

If you like this account please do give it a share! We are really struggling to get engagement on this platform. London’s geology is more varied than you think and we are here to spread the word, look after and promote London’s geosites #londongeology

Pendle Hill rises like the prow of a ship over Lancashire - famous for its witches but less so for its fossils! Most of the rocks of Pendle Hill are un-fossiliferous. You can however find a few fossils including these small bivalves (Posidonia) in scree on the flanks of the hill. #FossilFriday

We always do a #FossilFriday post on a fossil, but this week the fossil is on the post! (...groan...) Keep your eyes peeled for fossil plants in the Millstone Grit, they're everywhere! We spotted this piece of fossil plant in an old gate post near Keighley.

These shells are looking a bit bored! These circular drill holes were made by a predatory sea snail, which bored into the shell to feed on the creature inside. The fossil shell on the left is from the Jurassic of Grosmont. You can still see modern evidence of this behaviour today! #FossilFriday

There was an earthquake this morning in the Yorkshire Dales! Did anyone feel it? Shout out to the @britgeosurvey.bsky.social - if you are interested in British earthquakes or real-time seismograph monitoring, this is the website to go to... earthquakes.bgs.ac.uk/.../20250318....

In honour of William Buckland's birthday earlier this week, here is one of his hyena fossils! Buckland borrowed a live hyena in order to study its poo and the gnaw marks it left on bones. He then compared these with fossils from Kirkdale Cave in Yorkshire #FossilFriday 🏛️@morethanadodo.bsky.social

Happy 241st birthday to William Buckland! 🎂 Buckland's most famous link to Yorkshire was his investigation on the fossil bones of Kirkdale Cave, which led him to conclude the cave was an ancient hyena den!

As the weather improves, we're looking forward to getting back out into the hills to uncover more fossils and their stories. In the meantime, here is a lovely Stigmaria we found last autumn in the most Yorkshire sounding place of all the dales: Arkengarthdale! #FossilFriday

You wont find any pearls in this shell - but it's filled with calcite crystals! Brachiopod shells typically stay together after the animal dies, meaning when they are buried on the sea bed they become a pocket of space into which crystals can precipitate from mineral-rich water. #FossilFriday

Our goal is to celebrate Yorkshire's inland geology, but we have a confession: we're also experts on coastal fossils... If you're interested in the coast's palaeoheritage or are a palaeoart fan, check out this new book! Our team members Becky & Jed were scientific advisors for some of the artwork.

On this #FossilFriday in 1822, a significant event in the history of UK palaeontology occurred! William Buckland presented his study on fossils from Kirkdale Cave, providing evidence that hyenas once lived there rather than their bones being washed by a great flood. 🏛️ @leedsmuseums.bsky.social

Today is #FossilFriday and also Valentine's Day, so we've each selected a fossil that we love! Edestus - the whorl toothed shark from near Huddersfield (📷GB3D type Fossils 🏛️ @britgeosurvey.bsky.social)

We've had a great #FossilFriday digging through the archives of @sheffieldmuseums.bsky.social researching fossil trees. Many fossil tree stumps had a thin outer-layer of coal which often falls off when the tree is excavated This piece came from a stump near Barnsley and looks just like modern bark!

What does Settle have in common with the Atlas Mountains in Morocco? Surprisingly it's not the weather... This lovely cut and polished orthocone may look very similar to those exported from Morocco but it was collected from Settle in the Yorkshire Dales! 🏛️📷 The Yorkshire Museum #FossilFriday
