I think the volcanoes came in on giant asteroids.

I think the volcanos were giant hemorrhoids...

The depths of the ocean suddenly became starved of oxygen, wiping out swathes of marine life.

Too bad congress wasn't around to pass some laws to prevent the devastation.

So the Earth’s temp was twice the average temps of today, and Mars was probably the temp of Earth now. So why was it so much hotter? Is the sun dying out (slowly of course) or are we moving away from it?

a hothouse where the average temperature was nearly twice that of today.

Twice on which scale? The global average temperature is 58.1°F, 14.5°C or about 288 K. Which do you double? Would it be 116.2°F (average, $(#(#*( that is hot), 29°C (pretty hot, maybe Alaska would be nice), or 576 K (lead would probably melt in the daytime and refreeze at night). Kelvin is the only one of those scales in which you can really talk about doubling the temperature because its zero point is absolute zero.

Press idiots.

93 million years ago Alaska was equatorial, not because of continental drift, which isn’t happening, but because of pole flip. The pole, either north or south, hard to tell, was in what is now the Amazon.

I think the volcanoes came in on giant asteroids.

This theory lacks craterbility.
