Welcome to the Missing Dinosaur-Bearing Rock Formations List. There are quite a few formations that do not have articles on WikiPedia and if anyone is interested in creating pages (or expanding existing ones), fire away. Anyone able to add formations, either from red links or encountered while editing dinosaur articles, please do so.
The majority of the links come from a list prepared by Sheep81, off his own sub-page - the original list goes through to Late Cretaceous Period (pages have been created for some of these, since the creation of this list and some are possibly 'incorrect' links, which need alteration, rather than new articles):
