The problem with dinosaurs is that they lived a very long time ago- between 250 million and 65 million years ago – and the vast majority of our knowledge of them is based on fossilized bones and skeletons, which are all that have survived the ravages of time.

On the face of it there seems little hope of working out precisely how a 75ft long, 50 ton Brachiosaur fed itself. However it is possible to make a few guesstimates, by assuming the present laws of physics and chemistry applied 65 million years ago.
Examining how Bees work and interact reveals a highly organised and efficient ‘machine’. They appear to co-operate, communicate and work together as a unit with one purpose. But given that Bees don’t seem to communicate verbally, how do they do it?
Chameleons camouflage themselves in a variety of different ways but most famously by changing the colour and pattern of their skin.
