Denying a pole shift is laughable
The problem with the term pole shift is that it is used in many ways that differ from the original meaning as defined by Hancock. A pole shift as originally defined is a change in the orientation of the rotational axes. It is improperly used to indicate a change in the orientation of the magnetic axes. It is also improperly used to describe a magnetic reversal. This has led to a great deal of confusion in many threads.
Pole shifts as originally used by Hancock are not possible. There they are described as rapid events, some occurring within the last 12,000 years. The best understood event of this type was an event 800Ma that took 15My to complete. This is more properly termed a TPW or true polar wander.
Combined paleomagnetic, isotopic, and stratigraphic evidence for true polar wander from the Neoproterozoic Akademikerbreen Group, Svalbard, Norway
Geological studies show no TPWs in the last 200My although there has been a small amount of change during that time, but no single incident.

A proposed event from 84Ma has been disputed and is generally seen as a mistake in the interpretation of the available data.
