Snowflake is an Americanism. It's worth calling them out on that.

#FossilFriday from the chalk seas of #Yorkshire - a good day in the field yesterday sampling a working chalk pit containing outcrops of the 'Black Band'; corresponding to #Cretaceous Ocean Anoxic Event 2. Thanks to the folks at Ashcourt Group for facilitating our visit!

An outcrop of chalk with a tape measure for scale. A prominent layer of dark shale - the 'Black Band' - runs through the middle of the sequence.

A large chalk pit under a blue sky. A man in a high vis jacket and hard hat is examining the rock outcrops.

A close up of a finely laminated rock showing small fossil burrows- proof thst even during an 'Ocean Anoxic Event' there was life on the sea floor.

Thriving in the interglacial warmth of eastern England 120,000 years ago, a hippopotamus died and conferred its skeletal flotsam to the flood of time. A limb bone ended up in Waveney valley sediments, findspot uncertain.

So... my solution is evaluate my carbon footprint then pay a voluntary 'tax' to mitigate it 100% by sending money to native forest & peatland regeneration projects in the Highlands. Will that do?
If so, how to identify worthy recipients and how much to spend? #Caledonia @treesforlife.bsky.social

Macron remarks are notable- some quotes: "We have been incredibly naive in entrusting our democratic space to social networks that are controlled either by large American entrepreneurs or large Chinese companies, whose interests are not at all the survival or proper functioning of our democracies."

The landscape, lacking in shelter - winds horizontal, rain lashing, leaves turned inside out. Summer's last flowers fading. Winter wheat scurrying. Beets fattening their feet in clay. Rooks and gulls whirled away.
Miles to walk.
