A T-rex with lips? Predators with pink eyebrows? Walking with Dinosaurs is back to challenge everything you know

I’ve been under work pressure many times before, but nothing has prepared me for this. In Alberta, Canada on a palaeontology dig being filmed for the return of the BBC series Walking with Dinosaurs, I have been allowed to unearth a dinosaur bone.

It has not seen the light of day for about 73m years, and now, armed with just a hammer, awl and brush, I am chipping away at the rock around it to bring it to human eyes for the first time. One tap too hard in the wrong place and the fossilised bone could break.
