A new mass extinction…!
A new mass extinction has been discovered, wiping out life 233 million years ago, and leading to the rise of the dinosaurs
“Most everybody knows that the dinosaurs perished rapidly in a tumultuous extinction, caused by an asteroid strike about 66 million years ago.
But it looks like another extinction prior to the appearance of the dinosaurs paved the way for their long reign.
That extinction took place about 233 million years ago.
And scientists have only now discovered it.
The extinction took place during what’s called the Carnian Pluvial Episode (CPE).
Researchers have examined this period of time before, because they knew the climate changed abruptly then. The climate change was likely caused by copious volcanic activity that created Large Igneous Provinces (LIP).
But now a team of researchers have conducted a thorough review of geologic and paleontological evidence from that time and have concluded that a mass extinction took place.
The title of the new research is “Extinction and dawn of the modern world in the Carnian (Late Triassic).”…
The lead authors are Jacopo Dal Corso of the China University of Geosciences at Wuhan, and Mike Benton of the University of Bristol’s School of Earth Sciences. The new research is published in the journal Science Advances.
“So far, palaeontologists had identified five “big” mass extinctions in the past 500 million yeas of the history of life,” says Jacopo Dal Corso.”

Most of us understand that there was a mass extinction event that terminated the reign of dinosaurs.
Who among us knew that there were at least five extinctions that set and reset the table for human beings to come into existence and ‘dominate’ life on the planet?
This information requires rethinking the notion of ecological dominance by humankind and acknowledgement of the idea that all that has transpired and all that may occur in the evolutionary chain of events that comprise the history of life on this planet is temporary, and by the measure of time and the universe, fleeting.

I knew.
Keep well, Ron.

Nice hearing from you Jon…
I’m happy to know that someone was keeping track….
I stopped counting at two…I figured more would be kind of redundant….
Admittedly, that’s a rather shallow way of looking at it…
However, with things going the way they are re COVID19, another extinction event is a distinct possibility so I started surfing the web on the topic…
If it were left to Trump and his enablers and followers, we’d all be gone within a couple of years, unless of course we acquired a “herd mentality” before the virus could snuff us out…
Glad to know that you’re among those of us who have been able to keep half a step ahead of the ‘hoax’ that has killed more than 200,000 Americans to date…
We’re all supposed to be in this boat together but I’m not so sure I’d remain in it with Trump at the helm…
Stay well and VOTE!

Th e only mass extinction I am concerned about is the one we are in right now. We’re all on a count down timer.

Thanks Ron.
Glad to see Sunday a.m. has brought us a little something different for us to share.

I agree with Alan. We are fleeting in the vast scheme of things but we’d altogether rather not be more fleeting than we’d otherwise be due to our collective shortsightedness. (Wasn’t that a great euphemism?) To us, a great extinction event fifty million years from now (a geological blink of an eye) matters a great deal less than one fifty months from now.

This may be the first time I’ve ever seen something that occurred 233 million years ago as “new.”

Oops. “Referred to as ‘new.’”

It is about negative power — Putin’s incapacity to stand down. Our hate of Hitler. Our innocent suffer. The bold defend. Enuff: this ruble toss. Easter Sunday, Ten (10) Commandments prevail. Deep within rubble. Weather wrong. Tranquility as song.
Eternal question:
WHERE HAVE ALL THE FLOWERS GONE …?
33 degrees, 1:11 PM — an eternity off Friday’s lit sunset — last night’s moon rise — scarlet humanity blood — may we respond first — our concerted deep breath:

Since mass extinctions seem to be a regular occurrence this understanding puts the current inevitable extinction into a permanent event that catches up with evolution’s current progress towards the wiping away of the mass of life on the planet. Eventually, of course, evolution might well develop new life forms that are clever enough to colonize life forms that either live in interplanetary space or can survive on a sterile other planetary body like the Moon or Mars which humanity has almost attained but not quite. The abysmal ignorance and stupidity of current human culture obviously does not yet qualify and the time left for attaining that minimum goal is clearly not at hand. But life itself is incredibly tough and the automatic evolutionary process might still reach that goal within the time left before our planet plunges into the Sun.
