With regard to the activity for recovery of geological and palaeontological material from the cliffs of the Asturian coast since its start-up in 2005, the scientific department of the MUJA has recovered over 500 fossil pieces. The largest footprint of a theropod dinosaur known up to now, with a length of 82 cm, or the smallest ichnites of sauropod dinosaurs known about, of around 12 cm, stand out from among the abundant and varied palaeontological material of vertebrates recovered during the past few years from the surrounding cliffs and which have become part of the wealth of the Museum. The collection of dinosaur ichnites includes around 255 specimens and constitutes the most prominent collection of dinosaur tracks housed in a Museum in Europe, both due to its quantity and the variety and excellent state of specimen conservation. According to the distinguished palaeontologist Martin Lockley from the University of Colorado at Denver: 'the collection of ichnites of the MUJA represents one of the most complete worldwide' (Geotimes, January 2006).

On the other hand, the collection of vertebrates of the MUJA is the most complete for the Jurassic in Spain. The following stand out in particular: a partial skeleton of a marine crocodile, part of the jaw of a small ichthyosaur, a 1.25 m long ulna (equivalent to our cubitus bone) of a brachiosaurid, the partial skeleton of a stegosaurus, various bones belonging to plesiosaurs, many bone remains of marine turtles (including several shells) and several incomplete fish specimens.

Also, the MUJA houses a vast collection of fossil vegetables, the most numerous and varied of the Spanish Jurassic up to this moment.
