Geologist, writes on the history of geology and palaeontology, especially in the late 18th–early 19th C, and on the history of geology in Antarctica. Patron Lyme Regis Museum. Author of THE FOSSIL WOMAN A LIFE OF MARY ANNING (Dovecote Press 2020).

Some profound OCR here. From 'Elles (Gertrude L.) and Wood (Ethel M. R.). British Graptolites. Edited by Charles Lapworth' we get 'Exes (Gerrrupe L.) and Woop (Erner M. R.). British Graptolites. Edited by Cuartus Larworm'. Actually, Exes, Woop, and Larworm still sound like Edwardian geologists.

Delighted to see on Google maps that the dimples in the red sandstone of Calder Street (Govanhill) Baths in Glasgow are still there. Made by kids back in the mid 1960s grinding their (pre-decimal) pennies and ha'pennies into the stone while waiting to get in. Just testing rock hardness, of course!

200 years ago today, Mary Anning felt like giving up selling fossils. Sending a list to a dealer on 27 July 1826, she wrote, 'I belive they will be the last I shall ever offer for sale, as I cannot discover enough to get a maintenance therefor it is my intention to look out for some other pursuit.

Within a couple of days, a ton of rock containing skeleton was excavated and packed, with Mary Anning's help, and sent to Hawkins' home near Glastonbury where it arrived on 1 August. He spent 2 weeks preparing the specimen and had the 600 bone fragments set in plaster, restoring a missing forefin.

26 July 1832, Church Cliffs, Lyme Regis: fossil collector Thomas Hawkins and a team he employed begin the excavation of a large ichthyosaur skeleton. Hawkins had arrived in Lyme just as Mary Anning was extracting its skull, which he immediately purchased. The specimen is now @nhm-london.bsky.social

Lovely light and clouds above Traprain Law in East Lothian this morning, bringing out its lumps and bumps. An early Carboniferous laccolith, with an Iron Age hill fort on top (and site of the Traprain Hoard) and a disused 20th century roadstone quarry disrupting its curved outline on the left.

A rounded hill rising above fields with a grey cloudy sky above.

#FossilFriday: The Coade Stone ammonite pavement at the entrance to Lyme Regis Museum in Dorset. A modern version of the artificial stone perfected by Exeter-born Eleanor Coade (1733–1821) at her factory in Lambeth. From 1784 she owned Belmont House in Lyme which she decorated with her products.

An artificial rock, 'Coade Stone', packed with casts of the spiral shells of ammonites.

22 July 1826: newspapers report that Mary Anning's fossil shop had moved to premises on Broad Street, Lyme Regis' main thoroughfare. it was a small shop of two rooms, probably with a bay shop window on the ground floor, living accommodation upstairs and a thatched roof. She lived there until 1847.

One splendid animal is exhibiting, the Ichthyosaurus Tenuirostris'.

22 July 1775: birth of Wiltshire geologist Etheldred Benett. A contemporary of Mary Anning, and as well-known and respected, she donated fossils to the Geological Society from 1813, sent a measured section of a local quarry in 1815, and published a monograph on Wiltshire fossils in 1831.

The hill(s) I will die on. Arthur's Seat & Salisbury Crags are separate hills. Separate geologically, topographically and on Ordnance Survey maps. Yesterday's fire was on the slopes of Salisbury Crags. Many news sources, the fire service & even Historic Environment Scotland have got this wrong!
