The transition appears to have taken place in the early Cambrian.
There is a fossil record for forms that cross this transition.
References to some of the fossil descriptions and interpretations are
included below:

possible early Cambrian chordate," Nature 377 (1995): 720-722.

chordate," Nature 402 (1999): 518-522.
D-G Shu, et al., "Lower Cambrian vertebrates from south China," Nature
402 (1999): 42-46.
There are some other more recent articles.
This transition is included in my discussion of transitional forms in
my edited book "Perspectives on an Evolving Creation."
