William Willoughby Cole, 3rd Earl of Enniskillen

William Willoughby Cole, 3rd Earl of Enniskillen (January 25, 1807- November 21, 1886), was a British palaeontologist.

He was and educated at Harrow and Christ Church, Oxford. In his youth, as Lord Cole, he began to devote his leisure to the study and collection of fossil fishes, with his friend Sir Philip de Malpas Grey Egerton, and he amassed a fine collection at Florence Court, Enniskillen--including many specimens that were described and figured by Agassiz and Egerton. This collection was subsequently acquired by the British Museum. He was succeeded by his son (b. 1845) as 4th earl.
