'' fossil illustrated in Parkinson's
Organic Remains of a Former World '' found in the
London Clay on the
Isle of Sheppey and named for Parkinson, collection
Teylers Museum,
Haarlem, Netherlands Parkinson's interest gradually turned from medicine to nature, specifically the relatively new fields of geology and palaeontology. He began collecting specimens and drawings of
fossils in the latter part of the 18th century. He took his children and friends on excursions to collect and observe fossil plants and animals. His attempts to learn more about fossil identification and interpretation were frustrated by a lack of available literature in English, so he decided to improve matters by writing his own introduction to the study of fossils. In 1804, the first volume of his
Organic Remains of a Former World was published.
Gideon Mantell praised it as "the first attempt to give a familiar and scientific account of fossils". A second volume was published in 1808, and a third in 1811. Parkinson illustrated each volume and his daughter Emma coloured some of the plates. The plates were later reused by
Gideon Mantell. In 1822, Parkinson published the shorter "Outlines of Oryctology: an Introduction to the Study of Fossil Organic Remains, especially of those found in British Strata". Parkinson also contributed several papers to
William Nicholson's "A Journal of Natural Philosophy, Chemistry, and the Arts", and in the first, second, and fifth volumes of the ''Geological Society's Transactions
. He wrote a single volume Outlines of Oryctology'' in 1822, a more popular work. On 13 November 1807, Parkinson and other distinguished gentlemen met at the
Freemasons' Tavern in London. The gathering included such great names as Sir
Humphry Davy,
Arthur Aikin, and
George Bellas Greenough. This was to be the first meeting of the
Geological Society of London. Parkinson belonged to a school of thought,
catastrophism, that concerned itself with the belief that the
Earth's geology and biosphere were shaped by recent, large-scale cataclysms. He cited the
Noachian deluge of
Genesis as an example, and he firmly believed that creation and extinction were processes guided by the hand of God. His view on
Creation was that each "day" was actually a much longer period, that lasted perhaps tens of thousands of years. ==Death and memorials==
