The Evieux Formation, formerly included within the "Bois-de-Mouches Formation" and containing the Strud locality, is a late Devonian formation from Belgium. It preserves a wide range of fossils, including some of the earliest branchiopod crustaceans, various fish, and the putative insect Strudiella.
