A much awaited show has opened at the Hong Kong Science Museum, and judging by the sea of excited faces at the venue, the city's dino fans have got the memo. The Big Eight - Dinosaur Revelation is an immersive, interactive exhibition showcasing eight spectacular fossil skeletons as well as other fossil remnants.

Dinosaurs existed in all three periods of the Mesozoic Era, ruling the Earth for 165 to 175 million years - from around 240 to 230 million years ago until around 65 million years ago, when a massive asteroid collided with the Earth, triggering a global mass-extinction event.

The Big Eight showcases four dinosaur species - Allosaurus, Hesperosaurus, Diplodocus, and a juvenile sauropod - from the second period of the Mesozoic Era, the Jurassic; and another four - Tyrannosaurus, Triceratops, Spinosaurus and Hatzegopteryx - from the Mosozoic's third period, the Cretaceous. The exhibition runs concurrently with the 3D documentary short Dinosaurs of Antarctica, playing at the Hong Kong Space Museum next door.
