The Jurassic/Cretaceous sea - 150 million years ago

Hidden in deep wadis in the Emirate of Fujairah lie outcrops of marine rocks deposited at the time that dinosaurs flourished - 150 million years ago. These limestones belong to the Musandam Group of rocks that range in time from 200 to about 97 million years. In the northern part of Musandam these limestones were deposited in a deep-water sea that shallowed towards the south. These beds are now exposed in the vicinity of Ras al-Khaimah. Later, perhaps 70 million years ago, these limestones suffered severe tectonic events associated with mountain building in the Musandam area and were broken up into huge pieces. These pieces, some forming blocks as large as 30 metres in diameter, were incorporated into sediments of a younger age to constitute a mix of Musandam Group rocks of varying Cretacous ages.
