As I'm in my final year of a Geology degree, I feel qualified to have a go at this one...
James, come back when you have some physical evidence.
Continental drift/Plate Tectonics is essentially proven. Movement rates have been measured (a swift google image search will supply a plate tectonic map with movement rates marked on). The plates themselves can be seen as bathymetric or topographic features, and align beautifully with earthquakes.
As for fossils inland, it must be noted that the fossils are only found in rocks where you would expect the creatures to have lived. There is no evidence whatsoever for anything carrying shells and what have you inland.
Do you dispute the techniques used to date these fossils? Or perhaps the fact that one can correlate the same rock unit and fossil bed across miles of ocean? Or than one can trace the evolution of a species by moving upward through the rock record?
If dinosaurs had been a civillised society, one would expect to find evidence of their settlements primarily on unconformities in the rock record, rather than scattered throughout.
I've never seen a huge difficulty between tectonic plates and FET, but I suppose that is just me. I would think any Pangea-like construct would be far more damning to RET -- Imagine how the uneven distribution of weight would effect a globular world spinning at some one thousand miles per hour.
Thank you Ski, for some (relative) sanity! A point well made.
Any supercontinent is, inevitably, geologically unstable, and as such they usually don't last too long before they rift apart.
As for the weight balance, I suspect it does have an effect on the Milankovitch cycles (although I've not read any literature to support/refute).
Isostatic readjustment plays a role in equalising the densities of the planet. In simple terms, a big continent squeezes plastic mantle out of the way and sinks a bit. Plus, oceanic crust has a higher density than continental.
(may come back and edit when I've read the rest of this thread...)
