20 January 1814: newspapers report that entrepreneur William Bullock was sending a natural history exhibition to Edinburgh. Amongst the specimens is 'the fossil head of a crocodile, lately found in Dorsetshire', the ichthyosaur found by #MaryAnning & her brother, on perhaps its first public display.

18 January 1778, London: birth of George Bellas (Greenough from 1795), founding president of the Geological Society and compiler of the Society's 1820 geological map of England and Wales. In 1813 he visited Lyme Regis and purchased a fossil 'crocodile' from 'Mrs Anning's curiosity shop'. #MaryAnning

News from Lyme Regis, 17 January 1831: 'Miss Anning has again made a discovery of a grand fossil animal ... Geologists are now very numerous: perhaps much more than at any former period'. Then at the height of her fame, #MaryAnning and her discoveries attracted droves of fossil collectors to Lyme.

For #FossilFriday a small #IsleofWight iguanodontian dinosaur tibia in the collections @nhm-london.bsk.social. What makes it special is that it is from the Gideon Mantell collection. The fossil takes me back 125 million years but its history casts me back to the 1820s.

Great to learn today that a new mineral has been named after #MaryAnning. Anningite-Ce (Ca0.5Ce4+0.5)(VO4) was identified, appropriately, in a coprolite from the Cretaceous Gara Samani Formation in Algeria.

14 January 1836: Sir Philip Egerton tells his friend #MaryAnning that he has been taking his ichthyosaur specimens apart to study the neck bones 'like a little boy pulling my toys to pieces to see what they are made of' and asks for more specimens he can 'pull to pieces' for a paper he is preparing.

A wonderful place! In 1825 #MaryAnning led geologists Roderick and Charlotte Murchison on an excursion to the Undercliff. It was also where John Fowles (who lived at Underhill Farm, and later was Hon Curator of Lyme Regis Museum) set a key scene in The French Lieutenant's Woman.
A few photos from the amazing Undercliff, near Lyme Regis, Dorset: a topsy-turvy, otherworldly place, where the land is constantly swallowing itself, which proved to be a major inspiration for my latest novel... especially this extract: www.tom-cox.com/granny-kettl...

#FossilFriday: a partial ichthyosaur skull, the published figure from an 1822 paper (left), and a hand-drawn copy of the plate by #MaryAnning (right). Although unrecorded, the fossil may have been in the collection of Thomas Birch, and been found originally by Anning in the Lias of Lyme Regis.

8 January 1823: newspapers report on the first donation to Bristol Institution's new museum – a fine Ichthyosaurus communis from Lyme Regis, purchased for £50 from #MaryAnning by 9 of the Institution's members, including Henry De la Beche and William Conybeare who described Ichthyosaurus in 1821.

8 January 1766: birth of fossil collector Henry Henley at Sandringham House, Norfolk. He inherited property in Lyme Regis, leased land to Richard Anning in 1808, & in 1812 bought fossils from Mrs Mary Anning, including a 'fossil crocodile' found by young #MaryAnning & her brother on Henley's land.

Soon after the landslip occurred, geologists William and Mary Buckland, William Conybeare and Mary Anning were on the scene. William Buckland said it was worth coming 500 miles to see. Conybeare, the Bucklands & Exeter surveyor William Dawson published an illustrated account of the landslip in 1840.
This beautiful colour plate shows rock formations on the East Devon coast caused by landslips between December 1839 & February 1840. Corn grew on the rocks that had fallen from the fields above, attracting fascinated visitors.

As Mary Anning returns from the Christmas tree to her lair in the box of Anningiana, she'll shortly be joined by a prototype wooden Mary Anning peg doll, kindly sent to me by friends in Lyme Regis.

3 January 1802: birth of civil engineer & palaeontologist Proby Thomas Cautley who planned the Ganges Canal & with Hugh Falconer collected & published on the fossils of the Siwalik Hills. Cautley visited Lyme Regis soon after Mary Anning's death and purchased several books which had belonged to her.
