Eugène Eudes-Deslongchamps

Eugène Eudes-Deslongchamps (; 10 March 1830 – 21 December 1889) was a French paleontologist and naturalist born in Caen, the son of paleontologist Jacques Amand Eudes-Deslongchamps (1794–1867). He died at Château Matthieu, Calvados.

Around 1856 he succeeded his father as professor of zoology at the faculty of sciences at the University of Caen, later becoming a professor of geology and dean (1861). After the death of his father in 1867, he devoted himself to the completion of a memoir on the teleosaurs, the joint labours being embodied in his Prodrome des Téléosauriens du Calvados. He contributed several of his memoirs to the Société Linnéenne de Normandie.
