Valtos Sandstone Formation
The Valtos Sandstone Formation is a Middle Jurassic (Bathonian) formation found in the Inner Hebrides of Scotland. It is the thickest member of the Great Estuarine Group. The lithology consists of sets of approximately 6 metre thick cross bedded sandstone, capped by thin shelly limestones containing bivalves of the genus Neomiodon Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
