#EGU26 - check out the poster on our work presented by Dr Debs Tangunan: 'Unlocking UK Chalk macrofossil collections using calcareous nannofossil biostratigraphy: Insights into Late Cretaceous ecosystem change, resilience, and extinction' at booth X.350 in Hall 3 this morning.
What happens after a forest dies, a coral reef bleaches, or an oyster bed collapses?
A study of 10 ecosystems reveals that they carry memory. The material remains of foundation species can shape resilience, recovery, or collapse for decades in a changing climate.

#MolluscMonday is all about rudists! These unusual bivalve molluscs were very common in the Late #Cretaceous, especially in tropical settings around the Tethys Ocean. Individual or conjoined specimens occasionally appear in the UK Chalk but are often poorly dated.
Big #FossilFriday thanks to our curatorial colleagues @nhm-london.bsky.social who have been helping our project curate and register #chalk specimens! This week dealing with hundreds of cidaroid spines - these were originally attached to echinoids (sea urchins) which lived on the chalk seafloor.
#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).
We are at Lyme Regis #FossilFestival this weekend! Swing by the Hub to talk to our researchers and students about chalk sea #Cretaceous ecosystems and play our game 'pin the tail on the chalk fish'!
A great time was had at the 'Festival of Geology' today! Thanks @geolassoc.bsky.social and @geolsoc.bsky.social for having us, and to all the enthusiastic visitors who were interested in our work. Thanks especially to @spissatella.bsky.social and Tessa for sharing your knowledge and helping out.
Echinoderm and belemnite fossils in Ulster Chalk from Northern Ireland. This material is used for seating in @nhm-london.bsky.social Evolution Garden in South Kensington #fossilfriday #chalk #urbangeology
Emma Bernard presenting her research as part of @chalksea.bsky.social that samples chalk nannofossils fossils from over 1000 Cretaceous fossil fish specimens at @nhm-london.bsky.social to significantly clarify their stratigraphic context.

Correlation of the lower and middle Turonian chalks of south-west England and north-west France - condensation towards the Cornubian and Armorican massifs by Andy Gale

The dead remains of habitat-forming organisms can have powerful influences on the resilience of the ecosystems they inhabit.
If you're in #London today then come along to the @geolassoc.bsky.social FREE 'Festival of Geology' @geolsoc.bsky.social on Piccadilly. We'll be there showcasing some #chalk fossils and talking about our work on #Cretaceous ecosystems and environmental change. Come and say hello!
