The erf has been such a topsy turvy place with so much going on just since the breakup of Pangea, if in fact it ever happened, it makes every finding just a theory, an interpretation of the evidence.
The geologic evidence is similar to taking the bones from every animal sans flesh, putting them in a massive blender than tasking someone who has never seen any of the animals to sort the bones and tell us what animals were thrown into the blender.
Just about any answer is the equivalent of 10,000 monkeys with typewriters recreating Shakespeare.
I say this and I am an analytical engineer.

You are going to need several billion monkeys and billions of years.
And during the process they will be completing every other work of lessor number of letters, spaces, or numbers
