wealthy collector, and it was the latter who was credited if the find was of scientific interest. Along with purchasing specimens, many geologists visited Anning to collect fossils or discuss anatomy and classification. Henry De la Beche and Anning became friends as teenagers following his move to Lyme, and he, Anning, and sometimes her brother Joseph, went fossil-hunting together. De la Beche and Anning kept in touch as he became one of Britain's leading geologists. William Buckland, who lectured on geology at the University of Oxford, often visited Lyme on his Christmas vacations and was frequently seen hunting for fossils with Anning. It was to him Anning made what would prove to be the scientifically important suggestion (in a letter auctioned for over £100,000 in 2020 ) that the strange conical objects known as bezoar stones were really the fossilised faeces of ichthyosaurs or plesiosaurs. Buckland would name the objects coprolites. In 1839 Buckland, Conybeare, and Richard Owen visited Lyme together so that Anning could lead them all on a fossil-collecting excursion. Anning also assisted Thomas Hawkins with his efforts to collect ichthyosaur fossils at Lyme in the 1830s. She was aware of his penchant to "enhance" the fossils he collected. Anning wrote: "he is such an enthusiast that he makes things as he imagines they ought to be; and not as they are really found...". A few years later there was a public scandal when it was discovered that Hawkins had inserted fake bones to make some ichthyosaur skeletons seem more complete, and later sold them to the government for the British Museum's collection without the appraisers knowing about the additions. The Swiss palaeontologist Louis Agassiz visited Lyme Regis in 1834 and worked with Anning to obtain and study fish fossils found in the region. He was so impressed by Anning and her friend Elizabeth Philpot that he wrote in his journal: "Miss Philpot and Mary Anning have been able to show me with utter certainty which are the ichthyodorulite's dorsal fins of sharks that correspond to different types." He thanked both of them for their help in his book, Studies of Fossil Fish. Another leading British geologist, Roderick Murchison, did some of his first fieldwork in southwest England, including Lyme, accompanied by his wife, Charlotte. Murchison wrote that they decided Charlotte should stay behind in Lyme for a few weeks to "become a good practical fossilist, by working
