It was laid down in [[desert]] conditions from the [[Permian]] (280 million years ago) to the beginning of the [[Triassic]] (240 million years ago). It underlies the [[Jurassic]] [[Lias]], which are [[Ocean|marine]] rocks such as the [[Blue Lias]]. The term distinguishes it from the [[Old Red Sandstone]], which is largely [[Devonian]] in age. The New Red Sandstone is much brighter and redder in colour than the Old Red Sandstone, as the examples show. The colour is caused by [[iron oxide]]s in the rock. the red sand stone was formed from 416 million to 359.2 million years ago . it was washed up on the beach {{science-stub}} [[Category:Sandstones]]
