 On 22 August 1888, the American dinosaur expert Professor Othniel Charles Marsh visited Leeds' farm at Eyebury and quickly concluded that the presumed dinosaurian armour in fact represented the skull bones of a giant fish.Within two weeks British fish expert Arthur Smith Woodward examined the specimens and began to prepare a formal description published in 1889.In it he named the species "Leedsichthys problematicus".
