Portrait of Mary Anning wearing a green cloak and straw bonnet. Extract from a newspaper about a subscription raised to help Mary Anning after a fire at her home.

30 October 1846: a newspaper reported that a fund had been set up by the geologists at that year's @britsciassoc.bsky.social meeting in Southampton to raise money for ailing fossil dealer #MaryAnning, 'an old woman' (she was 47), following a fire at her home in Lyme Regis.

Fabulous to see our @EarthSciences students out there sampling the delights of @Derbyshire

The deadline has been extended!! Submit your abstract by tomorrow, 22nd of October lnkd.in/dBBx7Pne!

Scientists May Have Finally Detected a Solid Inner Core on Mars - Eos Seismic clues from NASA’s InSight mission suggest that Mars hides a solid inner core, and raise new questions about why the planet’s magnetic field disappeared.

Seismic data from the #NASA #InSight mission reveal a solid inner core at the center of Mars.

Google Earth satellite image showing a sinuous, ephemeral (currently dry), braided stream that is pale gray with trees within the channel. Red eolian sands are to the south (bottom) of the stream, whereas folded, black bedrock mantled with light brown to tan sediment lies north (top) of the stream.

A red eolian dune field to the south (bottom) of a sinuous, dark line marking a stream channel. To the north (upper half) is a desert of variagated back bedrock and light tan sediment. There is a dome popping out of the ground, looking like an eyeball, in the middle, upper 1/3 of the shot.

The 2025 Google Earth imagery is wild. We live on such an astoundingly beautiful planet.

Namibia (-23.6551610, 15.2430470). Close-up and wider view. In wide view: a structural dome popping out to say hello. Note the different eolian sediment compositions to N and S of the stream channel.

Last week I was co-leading a field trip in Utah, to check out some fluvial and eolian rocks. It was exhausting but fun and forced me to think more carefully than before about complex bedforms. This is a 3D model of one of the many stunning exposures of the Navajo Sandstone near Escalante 🧪⚒️

Some delicate actively growing stalactites from Ruakuri Caves, formed in Oligocene limestones. Skinny varieties are probably few decades old; the larger a few centuries. Ruakuri is the Maori name for Two Dogs - refers to early Polynesian canines brought to NZ. On a visit w a couple of grandkids
