Her account was subjected to the habitual skepticism of G.B.Greenough in his 1834 Presidential address to @geolsoc.bsky.social, a critique of Lyell's mountains formed by gradations vs elevation via volcanic force from below. He dismissed her account as she was not a naval officer observer of repute.

Just spotted the typo: it was, in fact, on 18 November 1825 (not 1826) that De la Beche read his paper on the submerged forest at Charmouth.
18 November 1826: At a meeting of the Geological Society, Henry De la Beche describes the submerged forest at Charmouth shown to him by Mary Anning, crediting her with the discovery. She was well known at the Society and her name appears in the minutes from which the meeting reports were published.

French palaeontologist and historian of geology (and Cuvier expert) Philippe Taquet who died yesterday aged 85. I recall that he cut a fine dash in his embroidered tailcoat and medals at the Geological Society's Bicentenary Dinner in 2007.

Hello again from Napoleon C, where a large crowd has gathered for the #HSS2025 distinguished lecture! Our speaker is Conevery Valencius, whose research draws connections b/w #histSTM, #EarthScience & #envhist.

Her talk tonight is entitled "Boom: What History of Science Needs to know About Shale."

Great series of talks today at the Yorkshire Museum on Women in geology with @toriherridge.bsky.social kicking things off with a talk on Mary Anning and on networks of women geologists in the 19th and early 20th centuries.

Another great talk today was on women in volcanology by @volcanologist.bsky.social who’s unearthing some wonderful, previously unrecognised contributions and observations by women travellers and others. Lots more to be learnt here such as who are the women in Tempest Anderson’s volcano photos?

#FossilFriday In 1828, Mary Anning found the first pterosaur skeleton outside Germany. W. Buckland made the announcement of Mary’s discovery & named Pterodactylus macronyx in allusion to its large claws bit.ly/1sEqnhU #WomenInSTEM #MaryAnning

9 November 1812: local newspaper reports the discovery of a fossil 'crocodile' 17 feet long at Lyme Regis. This was the recovery by Mary Anning of parts of the post-cranial skeleton related to a fossil skull found by her brother a year before. It was described and figured by Everard Home in 1814.

Have you seen the amazing Hutton Hat?

Handmade from Shetland Wool, showcasing three key Hutton Geosites - Edinburgh, Siccar Point, and Glen Tilt.

You can bag one of these in exchange for a donation to our crowdfunder - hurry, there are only 10 left!

And here is an insightful analysis and contextual evaluation that gives meaningful interpretation to the poem and accompanying cartoon:

Btw....can you spot the palaeontological ignorance of the illustrator and recognise the bowler-hatted/caped figure?

October 29, 1882, birthday of Scottish mineralogist and petrologist Samuel James Shand.
At college his first interest was chemistry, to this he soon added an avid curiosity about geology, combing both in his study of igneous rocks and mineral assemblages

Ganly (1809–1899) worked for Richard Griffith at the Valuation Office, Dublin but was de facto a geological rather than land/valuation surveyor. The detail on later editions of Griffith's impressive Geological map of Ireland (1852, 1853 & 1855) was due to Ganly. It should be the Griffith/Ganly map!

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.

A couple of days ago, a HOGG member paid an homage visit to Comrie, Perthshire, Scotland. 'Shaky Toon', as it is known, is v. important in the history of seismology. It boasts the oldest seismological observatory in the world: 'The Earthquake House', built in 1874. 🧵1/2

The exact date given by the Ussher-Lightfoot*-Chronology for the creation of Earth is October 23, 4004 B.C. in the early morning hours.
*John Lightfoot strongly influenced Ussher with his chronology published 6 years earlier

Reading William Whewell's 1832 review of Lyell's Principles of Geology, Vol 2, in which he coined "uniformitarianism", and I just love this passage summarizing what in many modern geological textbooks would describe as the principle of uniformitarianism.

Interesting and well-crafted French animation film of Mary Anning - great for watching with children or grandchildren and for learning French! We wonder if this will be dubbed into English at some stage? We suspect that is a high probability.

#AdaLovelaceDay: that Ada's contemporary, Mary Anning, was much more than a fossil dealer is clear from her letters with her observations on coprolites, the orientation of Pentacrinites and their association with fossil wood, and her dissection of living marine molluscs to understand fossil sepia.
