Also with one small ink stamp of the Rothamstead Experimental Station to endpaper. First edition. Plates engraved by Mrs. Mantell from drawings by the author. Gideon Algernon Mantell (1790-1852) was an English physician and geologist. This is Mantell's first work, and contains his early research into the fossil remains of the South Downs in southern England. Arranged by rock type and strata, Mantell provides descriptions of fossil plants, fish, molluscs and the teeth of what appeared to be a gigantic reptile, 'an animal of the lizard tribe, of enormous magnitude'. This volume was the first published work to describe a collection of dinosaur remains. Mantell's subsequent work on these remains was the origin of the scientific study of dinosaurs. [38172]
