There is a section in the museum known as “Dinosaur Alive” where they have a huge working model of Spinosaurus.
Spinosaurus: Spinosaurus (Thorn Lizard) was one of the longest and strangest of all carnivorous dinosaurs. A fully grown Spinosaurus was 15 meters long and weighed about 4 tonnes. The structure of the jaw and the skull suggests that Spinosaurus had a long, low skull and a kinked snout. Its crocodile like teeth were probably better suited for catching and feeding fishes. A large skin scale on its back must have been used for regulating the body temperature by aligning it to sun rays and thus warming up the blood.

Here are the descriptions about the dinosaurs written over there:
- Triassic World: The Triassic period (about 250-210 MYA) was the first phase of Mesozoic era (age of middle life), often called the age of the dinosaurs. All lands formed one super continent known as Pangaea. The climate was everywhere warm, mild or hot. No ice caps on polar lands, but desert spread in to inland regions. Palm like cycads and ferns grew in the moist ares. Life on land was dominated by prehistoric reptiles suited to dry conditions. In the late Triassic many of the older reptiles were wiped out and new kinds took their place. The most successful of these proved to be the dinosaurs.
- Jurassic World: The Jurassic period (about 210-140 million years ago) marked the middle of the Mesozoic era. By this time the super continent Pangaea was cracking up and rifts in the continental crust produced the Atlantic ocean. Africa began to split form South America and India prepared to drift towards Asia. The land was dominated by large dinosaurs including the largest of all land animals ever walked on earth. Jurassic period saw the first birds like Archaeopteryx have evolved form small dinosaurs.
- Cretaceous world: The Cretaceous period (145-65 million years ago) marked the last phase of the Mesozoic era and the climax of the age of the dinosaurs. Land mass was separated into continents that we know today. Flowering plants like Magnolia began to appear. Animals in the new isolated continents began to evolve separately. Fossil records point towards a large extinction of dinosaurs by the end of Cretaceous period. Scientists debate on various theories of extinction namely global climatic change, volcanic eruptions, catastrophes from space etc. Although the precise time scale is not known the extinction of dinosaurs might have happened in one hour or could have taken up to 100000 years during the end of the cretaceous period.
