Really?
They have a lot more than a partial skull. This is just one of the three found.
.......and no observation of it being produced by a lesser form and no observation of it changing into a superior form.
It is not a question of "lesser" or "superior".
They have preceding fish "forms", and later amphibian "forms" like Ichthyostega.
Tiktaalik has fins with wrists and simple digits. Fin/legs are a good illustration of transition.
{ABE} Realising that the topic is dating, I'll add that the discoverers of Tiktaalik were deliberately looking for such a creature in rocks that they knew were dated to the right period, demonstrating the validity of the dating.
