Dinosaurs - the word conjures up images of gigantic creatures like the majestic Diplodocus or the terrifying T. Rex. First classified in the late 17th century as terrible lizards (a misnomer given they are not reptiles at all), much of what we have learnt has been through careful study of dinosaur fossils, giving us clues about the ancient animals that roamed the Earth 230 - 66 million years ago. Of course not all of this information was faithfully replicated in Jurassic Park, but who are we to argue with Hollywood.
Rather than being slow, lumbering and a bit stupid, dinosaurs were smart and nimble-brained – just ask the palaeontologists who are peering deep inside the fossilised skulls of these prehistoric animals.

Every week we search for the best photos and images from the worlds of science, technology and nature: this week we found incredible images of the Mercury transit, a tea-making robot and a giant panda.
The number of dinosaur species in decline 50 million years before extinction and could have helped mammals take over.
