Marine life quickly recovered after global mass extinction

Mass Extinction Events

Ocean mixing led to recovery

At the same time, there were major changes in ocean chemistry and carbon cycling, the team found. Vertical mixing of oceanic water had stopped during or soon after the mass extinction, causing widespread depletion of oxygen in the oceans. Carbon isotopes in the Majiashan rock layers suggest the oldest marine reptiles appeared just after a return to healthy ocean circulation, which could have prompted the ecosystem recovery, the researchers suggest. The rocks recorded more vigorous mixing of ocean waters, which would have brought nutrient-rich waters to the surface to fuel tiny organisms at the bottom of the ocean's food chain.

Sorry. My graph post wasn’t proper.

Marine life were not on the ark. They survived the flood.

I caught this one last week on a treble hook with silver spinners!

That one may have drifted into a colder climate. LOL

I don’t know about cold, I was sweating like Michael Moore in a sauna when I finally landed it. ;-)

Did it taste like chicken?

Were you casting or trolling? What bait were you using?
If you don't want to share your secrets I'll understand. LOL

I hate to burst your bubble but I caught one so big I had to take two pictures of it to get it all in.

“Global climate change — likely triggered by massive volcanic eruptions — killed off more than 95 percent of all species...”

You can believe it was climate change - these scientists were there and saw it for themselves.

Oh, wait a minute...

No, everybody knows it was those evil SUVs.

My sweat? It tastes a little like BBQ sauce I’ll have to admit.

Oh, the critter! I’m strictly a catch and release guy.

[TigersEye]

Bait? I never use bait I’m a purist. Silver spinners trolling behind a high speed cigarette boat.
Don’t want one of those to catch up to you before it’s tired out.

I’d prove you wrong but I knocked my camera overboard in the fight.

Suppose we hitch our wagon to the hydrocarbon theory and the cause is something completely different and 1000 times more dangerous?

That would probably be a mistake since Most of the last 10,000 years were warmer.

It seems to me that liberals don’t care a whit about good science.
Reason and facts don’t seem to sway them at all.

[TigersEye]

LOL

I used to have a very hard time getting up in the morning. I put my clock radio on a rock station and turned up the volume. I would just fall back asleep with my favorite tunes playing in my dreams.

Then I put my alarm on NPR on normal volume. Within two minutes, guaranteed, I would rocket out of bed angrier than a hornet at the BS I had just heard with no possibility of falling back to sleep again.

Happily I don’t need an alarm anymore.

We only know about these events by their geologic fingerprints. Her money statement is: Vertical mixing of oceanic water had stopped during or soon after the mass extinction, causing widespread depletion of oxygen in the oceans. The restoration of the mixing of the layers of ocean certainly restored a habitat the destruction of which had decimated ocean fauna. Volcanic activity like that which over time created the Siberian Trapps put out plenty of nasty things CO2 is one of them.
