| Description | Watercolour study, with scale details, of an almost complete specimen [missing tail] of the fossil fish Thrissonotus Colei Agassiz, by Joseph Dinkel, [1834-1844]. Found in a concretion of hard Lias, Lyme Regis, from the collection of William Willoughby Cole, 3rd Earl of Enniskillen. Marked '18' in the corner. |
| Administrative History | The drawing is marked 'undescribed' which has been crossed out, probably indicating that it was part of the original commissioned artwork for Louis Agassiz's 'Recherches sur les Poissons Fossiles' (1833-1843/4). The specimen, which at that time was unique, is referenced in volume 2, part 2, p128. |
| Publication Note | Black and white lithograph, with description of fossil, published in: 'Memoirs of the Geological Survey...illustrative of British Organic Remains', Decade IX'. London: Longman, Green, Longman and Roberts (1858), plate II. |
