The Jurassic constitutes the intermediate period of the Mesozoic and goes from 200 and 145 million years ago; the final third of same being considered one of the times of maximum splendour of dinosaurs, in particular of the large sauropods.
The basic information to be transmitted to the visitor in this hall is centred on the classification and the ancestral relations between these singular reptiles, represented by means of a cladogram, together with the definition of the most characteristic features of the main groups.
The area dedicated to sauropods particularly emphasizes on several anatomical aspects such as weight, neck bonding, arm musculature, circulatory system and the relative size of the skull.
The theropod area is focussed on the offensive elements of dinosaurs, mainly their teeth and claws.
The exposition part dedicated to ornithopods is centred on the morphological characteristics most related to their vegetarian diet: toothless snout, tooth batteries, mobile skull bones, 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: bone shields, spikes, tail clubs, etc.
The central part of the hall is occupied by the skeleton of a Camarasaurus, a large-sized sauropod dinosaur, frequent in the deposits of central and western United States. Around it a large curved panel reproduces its aspect when alive and that of the ecosystem of which it was a part.
On the wall of the ramp surrounding the central hall is a space dedicated to the famous Hozmaden deposits in Germany. This exhibits a backlit panel representing a reproduction of the ecosystem of marine Jurassic vertebrates, including large reptiles such as ichthyosaurs and plesiosaurs, crocodiles and fish. An adjacent display cabinet also shows the replicas of the skeletons of an ichthyosaur (fish-shaped reptile similar to a dolphin) and of a sea lily or crinoid.
