<p><span>Although never formally introduced, the stratigraphic name </span>Wanship<span> </span>Formation<span> has become entrenched in the literature; recently, misunderstanding of its </span>age<span> and </span>correlation<span> has led to invalid interpretations of the structural evolution of </span>northeastern<span> </span>Utah<span>. The basal </span>Wanship<span> conglomerate has been erroneously correlated with a conglomerate within the Frontier </span>Formation<span> at Coalville. The Coalville section has been dated as Cenomanian-Coniacian. The </span>Wanship<span> </span>Formation<span> at its "type locality" is Campanian-Maestrichtian in </span>age<span>, as determined by its palynomorph content, and is not correlative with the Coalville section. The </span>Wanship<span> is correlative with the lower Evanston </span>Formation<span>. Recognition of these relationships obviates the need for a hypothesized episode of folding and faulting during middle Cretaceous time in </span>northeastern<span> </span>Utah<span>.</span></p>
