[2] Several landmarks are visible from the museum including the Bay of Biscay, the Sierra del Sueve, and the Picos de Europa.

[3] 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.

[3][9] Three ellipsoidal vaults intersect to form the deck space which is a large, open area of 2,500 square metres (27,000 sq ft).

A module explains the geological history of Asturias, focusing on the Jurassic Coast and the marine levels that formed the city of Gijón.

Martin Lockley, Palaeontologist of the University of Colorado Denver states that “the collection of ichnites of the MUJA represents one of the most complete worldwide”.

Also shown are the gastroliths (stones gulped down by some dinosaurs to crush food in their stomachs), coprolites (fossilized dung), eggs and nests.

Ornithopods, which are vegetarian by habit are shown with snouts, tooth batteries, mobile skull bones jowls and with hoped feet.

Thyreophorans exhibits depict their defensive anatomical features against predators in the form of bone shields, spikes, tail clubs and so forth.

Camarasaurus, a large-sized sauropod dinosaur, found in central and western United States are exhibited in their original curved form.

The exposition part dedicated to ornithopods is centred on the morphological characteristics most related to their vegetarian diet namely toothless snout, tooth batteries, mobile skull bones, and development of jowls and presence of hoofs on their feet.

The space dedicated to thyreophorans shows the main defensive elements of this group of dinosaurs against predators such as bone shields, spikes, tail clubs and so forth.

Marine Jurassic vertebrates are exhibited in the central hall alongside large reptiles such as ichthyosaurs and plesiosaurs, crocodiles and fish.

[13] In the Pre-Mesozoic hall, the exhibits relate to the time from the creation of the Earth 4500 million years ago to the Palaeozoic age, 251 million years ago with displays of first organisms on the Earth, evolution process of fossils and their dating, classification of the vertebrates and their inherited relations, deterioration and extinction of nearly 95% of these systems by end of the Palaeozoic period.

[15] Post-Mesozoic, representing the last 66 million years, starting with the extinction of a major part of the dinosaurs, is the Tertiary period when reptile, mammals and modern faunas evolved in that order.
