Jurassic Museum of Asturias The museum displays and collections cover 3,500 million years, and although they emphasize the three stages of the Mesozoic (Triassic, Jurassic and Cretaceous), information is also presented on the preceding and subsequent periods. Different stages of the Jurassic geologic period and system are on display. Corridors contain over 20 dinosaur replicas; measuring over in height, their weight would exceed ten tons if the replicas were real. A rich collection of footprints and fossils found in the Asturian Jurassic coastline from ten paleontological sites are exhibited in the exposition halls and are said to be "the most complete informative and representative
Wallowa Mountains addition there are many older terranes between the batholith and basalt flows. The Wallowa Batholith is formed of granite from a magma upwelling in Late Jurassic and Early Cretaceous time (between 160 million and 120 million years ago). The placement of this rock caused uplift of the surface, which at the time was tropical sea. This is evident from the slate, quartzite, and marble present in the mountains, which come from metamorphism of the sedimentary deposits of oceans during the Triassic. At the center of the Batholith are granodioritic rocks, while the outer limits of the range are tonalitic. The
