Firstly, though related, the tuatara is not a lizard. It is the sole 
surviving member of a group known as the sphenodonts. Together 
sphenodonts and squamates (lizards and those special legless lizards we 
call snakes) make up a group called the Lepidosauria wich is the sister 
group to the Archosauria. So it is a myth that the tuatara is a direct 
dinosaurian decendant.
