Why is coal rare at the beginning of the Triassic? and other questions.

I'm still around!

I came across this very good, but long video on the Permian-Triassic boundary (which is defined by a massive extinction event).

What jumped out to me was the lack of coal early in the Triassic. Interestingly, in the Northern Rivers the first major coal measures don't occur for many millions of years into the Middle Triassic. Those are the Nymboida Coal Measures.

But there is a lot interesting here so it is a recommended video.
