The gallery on prehistoric life features several life sized as well as scaled & animated robotic models of Dinosaurs and other extinct creatures in their natural ambience. Dinosaurs were the dominant land reptiles of the Mesozoic era. The word ?Dinosaur? comes from Greek, meaning ?terrible lizard? and was coined by the English Biologist Richard Own in 1842. Earliest dinosaur fossil records date back to upper Triassic era (230 million years ago). They dominated the Earth during the Jurassic era and continued until late Cretaceous era (65 million years ago) before extinction. Visitors can understand the life styles, food habits, their sizes, period of their existence on Earth in the presentation.
