as scientists got to grips with the scale of their find, they werejoined by sir david attenborough. he also got a chance to see what this titan of the cretaceous period might have looked like. now the exhibition is complete, the dinosaur is ready for its moment in the spotlight. so, one of the first things you notice is the huge toothy grin with these pencil—like teeth. they are constantly on the move, would have been just feeding machines. constantly using those heads to stuff more and more leaves and twigs and so on into its body just in order to keep it moving around. patagotitan still holds some mysteries. no—one knows why these creatures grew so big or how they came to die out, but their size and their success for millions of years puts our own existence into sharp perspective. rebecca morelle, bbc news.
