Dinosaurs died off about 33,000 years after an asteroid hit the Earth, much sooner than scientists had believed, and the asteroid may not have been the sole cause of extinction, according to a study released Thursday.
And the 33K years is still dumb,
Is the Tunguska event that happened in 1908 going to be responsible for extinctions 32,982 years from now?
Life recovers quickly, Tunguska for instance, if you go there today, most of the evidence is long gone. Same would have happened with Chixalub, even if it was a meteor, if it didn't kill it out right, whatever survived would rebound and back to normal numbers within a decade or two.
Yes, of course I read the whole thing. The idea that volcanoes played a role was the quirky view of the one guy on the team who was interviewed, so naturally that came out. The volcano alibi (that’s my name for it) was developed to combat the Alvarez theory when it emerged over 30 years ago. The unreconstructed Darwinists have been fighting it tooth and nail. In fact, the earlier “study” that invented the 300K gap was from that very same camp.
Life recovers quickly when it can come in from unaffected areas. The KT event was worldwide in affect, and the lifeforms which wound up making it through into the Tertiary (there’s a clear-cut boundary, that’s why there are paleontological eras in the first place) were some sea life, and species which lived in burrows, and were mostly smaller (food supply and water supply was constrained, probably for years, perhaps for decades).
Life dies quickly, it doesn’t take 33,000 years.
Same would have happened with Chixalub, even if it was a meteor, if it didn’t kill it out right, whatever survived would rebound and back to normal numbers within a decade or two.
The geologic evidence argues against you.
It has taken decades, and it is still being studied, but when Toba erupted, it was as close to a wordless-catastrophe as we can imagine.
Temps globally plunged about ten degrees Celsius for almost a thousand years.
Can we trace extinctions to that event? Perhaps not yet.
But the point being that events that show up on the geological record are MASSIVELY more extreme than “Well, we had a rainy May” type news.
