A bonus for #MolluscMonday, the first fossil I spotted today in Singapore, a sectioned ammonite on a polished slab of German Jurassic Treuchtlingen Formation used to clad a wall in Changi Airport.

#MolluscMonday The L.F. Spath collection at the NHM in London includes numerous thin sections through the early growth stages of ammonoids. This crudely photographed example is of a Cretaceous ammonite.

20数年ぶりに福岡市地下鉄天神駅を訪問。階段手摺りのサンゴ・ウミユリ・腕足類・クダサンゴなどの化石はまだ存在していました。よかったよかった。 石材はベルギー産のプチグラニ🇧🇪 #街の中で見つかるすごい石 #UrbanGeology #金曜日だから化石貼る #FossilFriday

#FossilFriday Painted black to enhance contrast, a pair of cheilostome colonies encrusting a test of Echinocorys from the English Chalk. Bryozoans are exceedingly common on the tests of this infaunal echinoid which had to be exhumed before encrustation.

For this #FossilFriday, something special for me: one of the few books on fossils in Turkish when I was a kid. 13 yo me was turning the pages, reading word by word to learn about fossils, dreaming about being a paleontologist. Many years later, at a Palaeontological Association conference dinner...

This is excellent advice for all first time presenters … also, the quality of your talk will not impact your future career - that comes down to your CV & skills overall, not your ability to perform on the platform. So, if you slip up a bit don’t sweat it - most of the audience won’t realise anyway 🤷🏻‍♂️

#MolluscMonday Balanced on a wall beneath the ice-cream parlour at Aubeterre (Charente, France) is a fossil of the large rudist bivalve Hippurites, probably collected from a local field underlain by Campanian limestones.

#FossilFriday Sectioned stems of the Jurassic crinoid Apiocrinus in the paving stones around the Place de la Bourse, Bordeaux. From Burgundy to Bordeaux.

#MolluscMonday Spirals from the Cretaceous: sections of fossil snail shells in the pavements of Libourne and Bordeaux, SW France.

Congrats Wolfgang! Very well deserved

#FossilFriday A bonus fossil for #Halloween: the ghoulish ‘face’ of a sectioned Carboniferous brachiopod from a Winchester Cathedral gravestone.

#FossilFriday The gravestone of the oddly named Connop Thirlwall in Westminster Abbey is made of black limestone (?Tournai Marble) containing horizontally sectioned productid brachiopods.

Congratulations to Abby Smith and Patrick Wyse Jackson, who were awarded the Ellis Medal at this year's International Bryozoology Meeting in Japan in recognition of their outstanding and honourable service to the community.

#MolluscMonday Handsome facsimile of a scallop shell on a plaque celebrating marine circumnavigation. Westminster Abbey cloisters.

#FossilFriday Not to be outdone by Isaac Newton who is buried beneath a gastropod fossil in Westminster Abbey, the famous geologist Charles Lyell’s gravestone is Carboniferous crinoidal limestone full of columnals of these ‘sea-lilies’.

I’m thinking of rebranding myself as a ‘Content Creator’ and an ‘Influencer’. After all, I create written content with the hope of it having some influence. Could this be a lucrative move?

‼️Special volume about arthropod paleontology was published today in the Journal of Paleontology, honoring the late Dr. Rodney Feldmann.🦀🦞🦐 Many of the 20 articles are open access. @paleosoc.bsky.social #paleontology #fossil #crab #lobster #shrimp Full volume: www.cambridge.org/core/journal...

#MolluscMonday Flattened specimen of the Early Jurassic ammonite Harpoceras photographed on the North Yorkshire coast in 2011.

It is also great to meet bryozoologist friends and colleagues 😊

Very cool! Thanks for sharing! I missed seeing the gastropod sev yrs ago at Newton's gravesite in Westminster Abbey. A reason to return. But, last month, saw a large nautiloid fossil on a step at Piazzo San Marco in Venice.

#FossilFriday This large slab in the NHMUK covered with screws of the Carboniferous bryozoan Archimedes was unknown to me until last week. For at least 46 years it has been lurking among large specimens in the coral collection.

Isaac Newton is buried beneath a fossil snail as I discovered yesterday when visiting Westminster Abbey. Near the centre of his gravestone is a rather nice section of a gastropod, probably from the Carboniferous.

Novel take on the ladder of progress iconography of human evolution from an album cover. The orthogenetic trend continues into the future with the huge brains of our descendants causing them to topple over in a manner reminiscent of old ideas about the massive antlers of the giant deer Megaloceros.

#FossilFriday Horizontal sections of concavo-convex brachiopods (probably productids) in gravestones of Carboniferous limestone in Winchester Cathedral. The outer rings are the convex ventral valves, the inner rings the concave dorsal valves.

Zooid size reduction in cyclostome bryozoans from the Late Triassic to the present-day onlinelibrary.wiley.com/doi/10.1111/... @datadryad.bsky.social

Always wonderful to do a bit of bryozoan work with @nhmbryozoa.bsky.social, led by Ma Junye from NIGPAS in Nanjing!

Here are the details of the shrinking bryozoan paper, as the dot doesn't seem to work.

#MolluscMonday: James Sowerby's illustration of Ammonites bucklandi from the Lias of the Bath district, in vol.2 of Mineral Conchology (1818), the description brightened by the tale of William Buckland being proclaimed an 'Ammon Knight' by his friends for his mode of carrying a large specimen.

#MolluscMonday Early Pleistocene Neptunea angulata from the Red Crag of East Anglia bearing a striking example of the shell repair trace fossil Caedichnus, normally representing failed attempts at predation by crabs. Would handling this sinistral snail have proved difficult for the crab?

#MolluscMonday The invasive freshwater bivalve Corbicula fluminea is becoming so abundant in the Dronne at Les Églisottes (Gironde, SW France) that it is beginning to form a shell beach.

Self repost because this is pretty cool imho

#MolluscMonday Photographed at Hampton Court Palace last week, orthocone nautiloids in paving slabs of Swedish Ordovician limestone. A microfault crosses the chambered phragmocone of one. The other fossil may represent a siphuncular structure but comments would be welcomed.

I just deleted my account. Not much use anyway and this is just too much... 🧪
