Theropod Ontogeny

["Simon M. Clabby" <dinowight@yahoo.co.uk>]

I'm not sure how to put this question scientifically,
so I'll put it into laymans terms.

Is you were to insert a peg into the top of the skull
of a living theropod dinosaur as soon as it hatched
(without killing it), if you went back to it when
fully grown, would the peg still be in the middle of
it's head, or would it has moved
posteriorly/anteriorly?

Basically, do theropods skulls grow anteriorly or
posteriorly?

I apologise for the slightly primary-school phrasing
of this question. Please feel free to rephrase it
scientifically/criticise.
