I am a T-rex fan, its not very original but it he was my first dinosaur love!
It started when my mum took me to see Jurassic Park when I was about 7. She took me to see it another three times in the cinema after that, bless her! (Hi Mum).
Random dinosaur fact: Did you know that we are closer in time to the T-Rex than the T-Rex was to the Stegosaurus? The Stegosaurus was around 150million years ago but the T-Rex was around only 65 million years ago.
