Christopher Scotese on early plate tectonics

[BillTre]

Christopher Scotese has done a lot of plotting out the positions of continents in the past based on a variety of geological clues.
In this video he discusses clues he uses when the more obvious ones are lacking.


I have been interested in this early geology stuff for a couple of reasons:

1. geological situation when the Danios (zebrafish are a member of this taxonomic group). Very complex tectonic movements were going on then (India ramming into Asia).
2. The conditions of the land and oceans at the times when life started. Where there continental masses at early geological times? Was there plate tectonics yet?
