Valtos_Sandstone
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 [1] Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.[2]
