#MolluscMonday Giants from the south. A display cabinet in the Sedgwick Museum, Cambridge houses huge rudists from the Upper Greensand (Albian) of Shillington, Bedfordshire, an unexpected occurrence in the British Cretaceous far away from the Tethyan homeland of these bivalves.

Neil Landman, Curator Emeritus at the American Museum of Natural History, reflects on his journey into paleontology, the aesthetic beauty and biology of #ammonites, and his groundbreaking research on post-impact survival near the Cretaceous-Paleogene (K-Pg) mass extinction boundary.

#FossilFriday Jane Austen might be the most accomplished writer commemorated in Winchester Cathedral but her black Carboniferous limestone memorial stone lacks obvious fossils, unlike the neighbouring gravestone for Richard Littlehale which contains syringoporid corals.

I'm incredibly excited to share our recent paper, "Temporal heterogeneity in the animal fossil record driven by proliferation of microbial collagenases", is now available in Current Biology!

#MolluscMonday Scratched by the feet of countless visitors unaware of its existence, a Carboniferous gastropod in a memorial stone in the cloisters of Westminster Abbey.

On cheilostome cyclostome distribution through time with @nhmbryozoa.bsky.social and @jgsaulsbury.bsky.social thanks @andrejpaleo.bsky.social I didn’t even see it was online.

#FossilFriday It’s easy to see why Cotham Marble is often referred to as ‘landscape marble’. This Late Triassic limestone from the Bristol area is a microbialite. Detail from a specimen about 10 cm thick on display at the Natural History Museum, London.

#MolluscMonday Section of a fossil gastropod shell in a Bordeaux street paving stone. I believe this to be an acteonellid of Cretaceous age but would welcome feedback.

#FossilFriday Scanning electron micrograph of the cheilostome bryozoan Fenestrulina from the Miocene of North Canterbury, New Zealand. Visible at the centre is an ovicell in which larvae were once brooded, and to the right the coiled tube of a fouling spirorbid tubeworm.

It's Tubulipora Thursday, so here is some images of Tubulipora ventricosa from the early stage of the #NorDigBryo project!
This is an Arctic species which can be found at depths between 12-250 meters.

This plate is from Volume 6, Issue 15 (1852), A Monograph of British Tertiary Brachiopoda. This issue is the first part of an enormous series of work published by Thomas Davidson in the Monographs of the Palaeontographical Society over 30 years.

#MolluscMonday Steinkerns of rudist bivalves are the most peculiar and perplexing fossils to be found in the Late Cretaceous rocks of SW France. The owners of the holiday home where this example was found assembled a collection of rudist steinkerns believing them to be dinosaur teeth.

Rev George Graydon was puzzled by Monte Bolca fossils and carried out experiments in Dublin in 1794. He observed fish as they rotted in water to leave skeletons. Graydon collection National Museum of Ireland @nmireland.bsky.social #fossils commons.wikimedia.org/wiki/File:On...
