I've not had the chance to explain my favourite geochronoetymology pet peeve on bluesky, so: Whether you're a 'paleo' person or a 'palaeo' person, it's NEVER 'Palaeocene'. The word comes from pal+eocene, not palaeo+cene.

Couple loaves of bere bread, made with Orkney bere, an ancient variety of barley. Rest of the flour is from East Lothian. Damn tasty stuff.

Wasn’t prepared for a day at home so didn’t get a chance to shop for bread before the storm hit. Luckily the power has lasted long enough to for me to bake my own.

Due to today's addition to my muted words list, I will sadly no longer be seeing updates about World Number One snooker player Judd Trump.

Our fragment of the Beinn Bhreac boulder is usually displayed with the spectacular amazonite pegmatite facing outwards. But when we move it for cleaning you get a great cross-section of the the vein from the host syenite to the centre of the pegmatite. #MineralMonday

Highlighting the glamour of the heritage sector this #MuseumSelfieDay. Today I had the great privilege of clearing out the sediment trap under the sink in the rock cutting lab. Probably a decade’s worth of sludge that partly ended up in my shoes.
