Catastrophe Cycle
Seasmith, you said: What do you think of Carlson's version of the "Cosmic Zodiacal Clock", for a possible sequence of catastrophic events?
I don't see much good evidence for the clock, i.e. for the multi-millennial cycle of catastrophes.
Cataclysms
The so-called Taurus age may be the time when the Great Flood or the Supercontinent Breakup occurred, or both. In the early part of this thread I showed a lot of evidence that the Great Flood occurred over 4,000 years ago and that the Flood was the cause of nearly all sedimentary rock formation, which covers most of the continents to about a mile deep. So it seems unlikely that anything before the Great Flood remains, other than the bedrock itself. All remnants of former civilization would be found mostly under sedimentary rock, just like the fossils. And all of the fossils were of the same time, not thousands or millions of years apart.
Flood
Carlson seems to think the Great Flood was due to sudden melting of huge ice caps. My guess is that he thinks comets or something fell on the ice caps and melted them suddenly. But I think a lot of the evidence of great ice caps may be better evidence of the Great Flood itself, or of smaller floods. So I'm not yet confident that there were great ice caps much bigger than the present ones.
This is the best explanation of the Great Flood that I've read: Noah’s Flood: The Key to Correct Interpretation of Earth History

Halloween Cycle
It's plausible that catastrophic cosmic cycles may exist, but it seems merely theoretical for now. Carlson's Halloween video did make a convincing case that great catastrophes did occur each year around Halloween and in late June or July, because the Earth was moving through the Taurid Meteor Stream twice a year and the stream likely had a lot of larger meteors or asteroids in it initially. So the cycle stopped being catastrophic after several decades apparently. It's possible that the cycle started with a Venus encounter.
