In ancient oceans that resembled our own, oxygen loss triggered mass extinction

By: Zachary Boehm | Published: March 27, 2019 | 3:34 pm

Roughly 430 million years ago, during the Earth’s Silurian Period, global oceans were experiencing changes that would seem eerily familiar today. Melting polar ice sheets meant sea levels were steadily rising, and ocean oxygen was falling fast around the world.

At around the same time, a global die-off known among scientists as the Ireviken extinction event devastated scores of ancient species. Eighty percent of conodonts, which resembled small eels, were wiped out, along with half of all trilobites, which scuttled along the seafloor like their distant, modern-day relative the horseshoe crab.

Now, for the first time, a Florida State University team of researchers has uncovered conclusive evidence linking the period’s sea level rise and ocean oxygen depletion to the widespread decimation of marine species. Their work highlights a dramatic story about the urgent threat posed by reduced oxygen conditions to the rich tapestry of ocean life.

The findings from their study were published in the journal Earth and Planetary Science Letters.

1. Wow, Reading This I Wondered If These Things Were Real

Sounds so alien. Trilobites..made me think of tribbles.

3. Trilobites certainly weren't powder puffs

4. I Repeat...Wow

Proetids, Permian, Atdabanian stage, Devonian and so on and so forth

2. Well, that's obviously fake.

It could not have happened. The earth is only 6,000 - 8,000 years old.
