This March we're holding another Primary Teacher CPD session at our Nottinghamshire HQ.

The free session will guide you through everything you need to know to teach rocks, fossils and soils to your KS2 classes.

Places are limited so book early!

Rethinking the meaning of carbonate facies
Rethinking the meaning of carbonate facies YouTube video by Seds Online

My @sedsonline.bsky.social talk is now available on YouTube, if you missed it or just feel like hearing what I have to say about the fundamental concepts of facies in carbonate sedimentology, and how we need to rethink them. πŸ§ͺβš’οΈπŸŒŠ

Portrait of Mary Anning in a green cloak and straw bonnet tied with a red ribbon, and holding a hammer. Below, an extract from a newspaper: 'Lyme Regis, Jan. 17. - 'Miss Anning has again made a discovery of a grand fossil animal. We shall perhaps be able in our next to give an account of the species and appearance of it. Geologists are now very numerous: perhaps much more than at any former period'.

News from Lyme Regis, 17 January 1831: 'Miss Anning has again made a discovery of a grand fossil animal ... Geologists are now very numerous: perhaps much more than at any former period'. Then at the height of her fame, #MaryAnning and her discoveries attracted droves of fossil collectors to Lyme.

What a superb day yesterday. As part of @originalgcg.bsky.social annual seminar, I went walking in the footprints of giants - mainly Iguanadonts. Between Pett Level beach & Fairlight Cove, I observed dinosaur trackways, tail marks, bone beds, fossil wood and ripples βš’οΈπŸͺ¨πŸ¦• @derbyuni.bsky.social

Yesterday I attended the annual seminar of the Geological Collections Group @originalgcg.bsky.social to learn about putting our collections to work. I presented a poster on @derbyuni.bsky.social collection: emphasis on our unique holistic approach to making our specimens accessible to students.
